ASLR and DEP in Delphi, How to tell? - delphi

From http://blogs.msdn.com/b/michael_howard/archive/2007/04/04/codegear-s-new-delphi-2007-supports-aslr-and-nx.aspx,
I am using {$SETPEOPTFLAGS $140} in my project file right under the program name to get address space layout randomization (ASLR) and DEP.
How can one tell if the flags are set in the PE? PeStudio seems to have the info, but doesn't seem to work.
Thanks.

The easiest way that I know is to use Process Explorer on the running app. Just double-click on the process and read it out of this dialog:

Need to add both header inside the application project file:
{$SETPEOPTFLAGS $140} //add this line
{$SetPEOptFlags $140} //and this line
between begin and end.

How to Auto-Alignment Shortcut Key in Keil uVision?

I want to find Auto-Alignment Shortcut Key in Keil uVision. I tried some shortcut keys but I can not find. In Visual Studio I used to: CTRL + K + D , but in keil uVision I don't know how it is work.
For example :
When you type below ( usually copied from another text file which was not tabified correctly):
Use the shortcut key Auto Alignment with this block of code can auto formatting your code as below :
Stop searching. There is no such feature.
Was able to align in uVision5 with Astyle (http://astyle.sourceforge.net/).
File must be saved so that this tool can do its work.
Instructions :
Copy the Astyle.exe file to the Keil installation directory (e.g. D:/Keil_v5/)
Then open Keil and under the Tools menu, open the Customize Tools Menu option.
Create a new Menu Content, the name can be casual .
Command selects the Astyle.exe file in the keil installation directory.
Fill in Arguments !E
You can add a shortcut key for the operation in Edit.

How to open source file in IDE on a certain line through command line

I'm just wondering if there is some IDE command line parameter which would open a source file on a specified line (in the current view) ?
I know this is probably too much to publish as a command line parameter, but it would be great for my Assert logging system; I would just create a link (label or something) and through this link open the file on the line where the assertion has happened.
The only thing I found is the registry entry (valid for Delphi 2007)
Key:
HKEY_CURRENT_USER\Software\Borland\BDS\5.0\Closed Files\
Value:
TSourceModule,'<FilePath>',0,<PositionX>,<PositionY>,<CursorX>,<CursorY>,0,0,,
Where:
<FilePath> - the full file path
<PositionX> - first visible char in horizontal scope
<PositionY> - first visible char in vertical scope
<CursorX> - cursor position in horizontal scope
<CursorY> - cursor position in vertical scope
The rest of this key value I don't know but it might be enough to create this key and open the file.
Thanks
Following discussion in the comments to the question, it appears that you would be satisfied with writing a small utility to generate a fake .dsk file (desktop file) and possibly a matching fake .dproj file (project file). The .dsk file would contain just enough information to trick the IDE into opening the required file and moving to the desired location within that file.

Delphi .res file changer

I'm looking for a ready-to-use piece of code that would be able to read and modify Delphi .res files. The thing is that I need to create an application that will be compiling many Delphi projects at once (using the dcc32.exe file). However, it is necessary for me to change file version and language before compilation, and as far as I know, I have to modify the .res file to do that.
Have you come across any code that would give me an interface to .res files allowing me to modify the data contained in it? The thing is that I want to change only those two pieces of information keeping the rest unchanged. This is why I can't compile my own .res file based on a script.
An application executed from a command line would also be OK if it allows to be called with parameters and does what I need it to do.
Thank you very in advance!
If all you need is to add file version resource then create appver.rc file, compile it with brcc32 and in one of your app unit (for example appver.pas) add {$R appver.res} (as Marian noticed you must turn off Delphi project option to include version info).
I created command line programs that increase build numbers in .rc file, create new branch/tag in SVN with new version in branch name, compiles .rc to .res, and build application.
My .rc files with such info (Polish language) looks like:
#define IDR_VERSION1 1
IDR_VERSION1 VERSIONINFO LOADONCALL MOVEABLE DISCARDABLE IMPURE
FILEVERSION 7,28,7,17
PRODUCTVERSION 7,28,7,17
FILEFLAGSMASK VS_FFI_FILEFLAGSMASK
FILEFLAGS 0
FILEOS VOS_DOS_WINDOWS32
FILETYPE VFT_DLL
FILESUBTYPE 0
{
BLOCK "StringFileInfo"
{
BLOCK "041504E2"
{
VALUE "CompanyName", "xxx\0"
VALUE "FileDescription", "yyy\0"
VALUE "ProductName", "zzz\0"
VALUE "FileVersion", "7.28.7.17\0"
VALUE "ProductVersion", "7.28.7.17\0"
}
}
BLOCK "VarFileInfo"
{
VALUE "Translation", 0x0415, 1250
}
}
For all things .res, look at Colin Wilson's "XN Resource Editor", for which he provides the source code: http://www.wilsonc.demon.co.uk/d10resourceeditor.htm
And probably all you need is his resource utility library:
http://www.wilsonc.demon.co.uk/d9resourceutils.htm
I haven't used this source, but if I needed it, that's the first place I'd look. His resource editor is very useful, btw.
There is ChangeRes which seems to match your needs.
Check out sources:
http://code.google.com/p/gedemin/source/browse/trunk#trunk/Gedemin/Utility/IncVerRC
It is our utility which reads .RC file with version information and increments build number. We use it inside our build process. Here is an excerpt:
incverrc.exe ..\gedemin\gedemin.rc
"%delphi_path%\brcc32.exe" -fogedemin.res -i..\images gedemin.rc
"%delphi_path%\dcc32.exe" -b gedemin.dpr
The utility uses TIncVerRc class written by Chris Morris.
Check Resource Tuner Console on www.heaventools.com. They position that product for tasks like yours. Also there's a free rcstamp tool on CodeProject.

Opening File paths with spaces in Delphi 5

(Using Delphi 5)
I am attempting to open a log file using the following code:
// The result of this is:
// C:\Program Files\MyProgram\whatever\..\Blah\logs\mylog.log
fileName := ExtractFilePath(Application.ExeName) + '..\Blah\logs\mylog.log';
// The file exists check passes
if (FileExists(fileName)) then
begin
logs := TStringList.Create();
// An exception is thrown here: 'unable to open file'
logs.LoadFromFile(fileName);
end;
If I relocate the log file to C:\mylog.log the code works perfectly. I'm thinking that the spaces in the file path are messing things up. Does anyone know if this is normal behavior for Delphi 5? If it is, is there a function to escape the space or transform the path into a windows 8.3 path?
I'm pretty sure that Delphi 5 handles spaces in filenames ok but it has been a very long time since I have used that specific version. Is the file currently open by another process? It also could be a permissions issue. Can you instead of loading it into a tStringList, try opening it with a tFileStream with the filemode set to "fmOpenRead or fmShareDenyNone".
fStm := tFileStream.Create( filename, fmOpenRead or fmShareDenyNone );
then load your tStringlist from the stream:
Logs.LoadFromStream ( fStm );
Are you sure its not the "..\" thats causing the problem rather than the spaces. Have you tried to see if it works at
c:\My\Path\nospaces\
If so and you are always using the ..\ path, maybe write a simple function to remove the last folder from your application path and create a full correct pathname.
It's odd that Delphi 5 would throw errors about this. I know of an issue with FileExists failing on files with an invalid last-modified-date (since it internally uses FileAge), but it's the opposite here. Instead of using "..\" I would consider risking the current path, and loading from a relative path: LoadFromFile('..\Something\Something.log'); especially for smaller applications, or by calling ExtractFilePath twice: ExtractFilePath(ExtractFilePath(Application.ExeName))
I'm pretty sure Delphi has always handled spaces so I doubt that is the issue.
You don't show the full path. Any chance it is really long? For example I could believe an issue with paths longer than 255 characters.
It's also a bad idea to put log files under Program Files. Often normal users are not given permission to write to anything under Program Files.
Delphi 5 can open files with spaces - that is certainly not the problem. To prove it, try copying it to c:\my log.log- it should open fine.
Is there any more information in the error message you receive? The most likely thing is that someone else (perhaps your own program) is still writing to the log.
The spaces are not a problem. While the '..' could be a problem in Delphi 5, mosts probably the file is locked by the process that writes to it. If you have control of it, make sure it opens the file with fmShareDenyWrite and not fmShareExclusive or fmShareCompat (which is the default).
Also, you can use:
fileName := ExpandFileName(ExtractFilePath(Application.ExeName) + '..\Blah\logs\mylog.log');
to obtain the absolute path from a relative path.
Also, as others have said, it is not good idea to write anything in Program Files. Regular users (that are not Administrators or Power Users) do not have rights to write there (although in Vista is will be virtualized, is is still not a good idea). Use the appropriate Application Data folder for the user (or all users). This folder can be obtained using:
SHGetFolderPath(0,folder,0,SHGFP_TYPE_CURRENT,#path[0])
where folder is either CSIDL_COMMON_APPDATA or CSIDL_LOCAL_APPDATA. See this delphi.about.com article for an example.
Simple :
// if log file = "C:\Program files\mylog.log"
// you'll get :
// »»»»» fileName = 'C:\Program files..\Blah\logs\mylog.log'
// if log file = "C:\mylog.log"
// you'll get :
// »»»»» fileName = 'C:..\Blah\logs\mylog.log'
Try this code instead, I'm pretty sure it will fit your needs :
fileName := IncludeTrailingPathDelimiter(ExtractFilePath(Application.ExeName))
+ '..\Blah\logs\mylog.log';

Delphi 5 has never had a problem opening files with spaces and I am still using it since it is uber stable and works great for older XP apps. You need to check your code closely.

Delphi: EReadError with message 'Property Persistence does Not Exist'

My program written with Delphi 7 compiles OK, but when I run it it gives me the error message:
Project1.Exe raised exception class EReadError with Message 'Property Persistence does Not Exist'. Process Stopped.
This only started after I installed the TMS Component Pack to use with this project. Thanks for any help.
Open the Form in Delphi IDE
Use Alt + F12 to edit the .DFM source
Search the "Persistence" property
Delete the line with "Persistence" property
DFM example:
SomeComponent1 = TSomeComponent
OtherProperty = OtherValue
Persistence = True
AnotherProperty = AnotherValue
end
Also you can use the great DFMCheck 1.4 tool, by Andreas Hausladen. To check any other missing property like that:
http://andy.jgknet.de/blog/?page_id=177
This is most likely caused by the compiled & installed package being out of sync with the actual .pas file. If you have source code then rebuilding the packages will probably fix it.
Set a breakpoint(F5) and step the program(F7/F8).Get to the location where you get that exception and then give us more information about it(show some code).
This error means that it's trying to load something (usually a form) from a DFM resource and it comes up with a value for a property that the component it's creating doesn't have.
If it only happened when you started using TMS components, the solution is simple: don't use them. Send as much information as you can about the error and the project that caused it to the authors and see if they can find a way to fix it. Until then, use something else.
If you're using text DFMs (right click on the form, check "Text DFM", save), you can use Search|Find in Files to find all instances of Persistence in your DFM files. Just set the search string to "Persistence" (I usually tell it to ignore case), the file mask to "*.dfm", and check the "All files in project" checkbox.
If you're not already using text DFMs and don't want to manually open all forms and check the box and then resave them, you can use CONVERT.EXE (in the ($DELPHI)\Bin folder) to convert them en-masse. Run CONVERT with no parameters from any command prompt to see the options. By default, CONVERT will save .DFM as .txt, but you can have it work in-place (rewriting the binary .DFM as the text .DFM) by using the -i switch. (I usually back up the .DFMs to a different folder first, then convert them. If no errors are reported, I can then delete the backed up .DFMs later.)
I had similar problem with TMS when I upgraded to a new version:
If you think that some particular component is causing the problem,
delete it , compile project without it, place it on the form/frame again.
If that doesn't work for you:
Things you need to do in order to fix the problem , so you can use Designer and new properties, because that's what you really want , don't you ? :-) :
Uninstall TMS Component Pack ( or whatever you're using )
Re-Install TMS Component Pack
Build & Install the packages
Add appropriate TMS .lib files to your Application Project ( I'm using C++ Builder )
Add appropriate TMS .pas files to your Application Project . For example I had a problem with TAdvSmoothCalendar component , so I've added the AdvSmoothCalender.pas to my project.
Cheers!
I hope it works for everyone with a similar problem :)
I had similar problem with nuiGui Delphi Framework,
To Solve this, create a include file with some properties and use it in your class.
/// include class 'Basic.inc'
private
function GetWidth: Integer;
published
property ClientHeight : Integer Read FHeight Write FHeight;
//property ClientWidth : Integer Read FWidth Write FWidth;
//property OldCreateOrder : Boolean Read FOldCreateOrder Write FOldCreateOrder;
end;
...
/// main class like this
TuMemoFrame = class(TUniFrame)
UniMemo1: TUniMemo;
UniMemo2: TUniMemo;
UniButton1: TUniButton;
procedure UniButton1Click(Sender: TObject);
private
public
{$Include Basic.inc } // <---
end;
