What is dclsmpedit? - delphi

What is dclsmpedit package (Embarcadero Editor Script Enhancements)?
Do I need it?
I am not sure what 'Editor Script Enhancements' does.

It's a sample of adding key bindings (your own code editor keyboard assignments), the ability to save keyboard macros (keystrokes recorded for playback), and an edit buffer list to the IDE using the ToolsAPI. You only need it if you want to use it 's functionality. The source is useful if you want to extend the IDE via the parts of the ToolsAPI that they demonstrate. The key binding functionality in BufferList.pas implements the New IDE Classic key mapping in the IDE itself (as pointed out by #LURD in the comment below).
If you're using Delphi 2007, you can find the source in the Delphi Demos folder (by default on Windows 7 in C:\Users\Public\Documents\RAD Studio\5.0\Demos\DelphiWin32\VCLWin32\ToolsAPI\Edit Keybinding), and more easily found with the Start->CodeGear RAD Studio->Samples menu item. The source for the added functionality is there as well, so you can see what they do and how they are implemented.
In XE3, the source code can be found in C:\Users\Public\Documents\RAD Studio\10.0\Samples\Delphi\VCL\ToolsAPI\Editor KeyBinding, or via Start->All Programs->Embarcadero RAD Studio XE->Samples.

Cannot add TMS async components to win32 firemonkey program

I have a firemonkey app targeted only at win32. I want to add the tms async serial communications component. When I do so and try to build it gets upset trying to compile the tms source code. It is non-trivial to change the tms source code.
Where is it picking up the library path to the source code? If I remove that path will it use the existing .dcu files and work? Is there any other suggestions?
What was catching me is that even though I had removed the directories from the options search path,, I had one of the tms rtl files still open in the ide. As a precaution, I also went and moved the tms source files elsewhere...
The form compiled and the components work.

delphi integrate custom file editor into IDE

I have deveoped a custom file type, together with a custom editor (basically a tree with several data pages attached and a few extra buttons). OK, I can run it stand alone and that is fine, and even add it to the tools menu, but I would like to integrate it into the Delphi IDE so that my custom editor (or a similar new version) appears in the IDE, rather like a DFM file has a custom editor. I can find references to most extensions in the Delphi IDE, but not this one. Any guiding hands? Note that this is not a property or component editor (the file type has nothing to do with either of these) nor is it simply syntax highlighting of a text file.
AFAIK it currently isn't possible to reliably integrate a custom editor into the Delphi IDE. The required API simply isn't there. See QC89028 Custom Module support.
During the Delphi 2010 and XE betas I spent most my spare time trying to get a resource editor integrated. Although the effort had the official blessing of Embarcadero and got some, half hearted, support from the IDE engineer, I was never able to get them to deliver on their promises and surface the module API. I eventually abandoned the project.
Update: I've now checked my old correspondence regarding this and it turns out part of the problem was that IOTAModuleCreator (used to implement File|New for custom file types) and IOTAEditorContent (used to transfer data to/from the custom module) only supports text data. Binary data gets mangled.
You can probably do this via an IDE plugin that uses the ToolsAPI (see ToolsAPI.pas in the IDE's source folder (e.g. Program Files (x86)\Embarcadero\Studio\source\ToolsAPI\ToolsAPI.pas.)
For information on writing a plugin in general, see David G Hoyle's excellent blog. Once you know the basics - i.e., write a 'wizard' and get it to do something - you will need to work on integrating your editor.
I have never done this, and so I can't guarantee it is possible. However, some interfaces that look worth investigating and implementing are INTACustomEditorView, which represents a 'view' (file tab when that file is open - think the code editor, Welcome view, type library editor, etc) and IOTAEditorViewServices, to register your custom view. I do not know how you associate a view type with a file type, sorry - possibly something to do with the personality interfaces. You might also be interested in INTACustomEditorSubView which is what creates a tab on the bottom of a file.
Good luck, and if you find a solution please write here so that other people can learn too!

Delphi unit for msctf.h header file (from Platform SDK)?

Is there any Delphi unit available corresponding msctf.h header file from Platform SDK?
I have checked Delphi 2010 source folder, but it seems Delphi doesn't come with that.
Thanks in advance for your time!
You can use Visual Studio's MIDL to generate a type library (.tlb) from the .idl file and then use Delphi's tlibimp.exe to generate the Delphi interface unit.
The problem with the original .idl is that it doesn't contain a library statement so I added it manually (otherwise MIDL wouldn't generate the .tlb).
See if the result helps you (you may still need to fix some parts by hand).

Code templates - unit name clash between Delphi versions

Different Delphi versions (in my case 2007, XE and XE2) seem to use the same code-template repository, such as ..\Documents\RAD Studio\code_templates. Since XE2 uses namespaced units, this causes problems when one have to use a unit name in a template.
For instance I have a template when I write winbeep which completes to windows.Beep(300, 100); and selects and stops on frequency etc.. This does not compile on XE2 unless I remove the Winapi. part of the Windows unit in the uses clause (or of course add the prefix manually). I have to have the unit name because otherwise SysUtils.Beep gets referred.
I couldn't find an option entry or a registry key or an environment variable specifying the place of the templates. It is not even related to BDSUSERDIR, in fact I don't even have a directory in my computer having the path of BDSUSERDIR (which is ..\Documents\RAD Studio\9.0). Is this my oversight and in fact there's an option to relocate code templates? If not, is it possible to make the IDE use unit aliases in uses clause for new forms?
edit:
Here it is stated that (emphasis by me) "Templates that you create (and templates provided by third party add-ins) are saved by default in the \My Documents\RAD Studio\code templates\ directory." That would imply there should be way to save them in a non-default place. But the article does not mention how.
You can put your templates in "Delphi installation folder"\ObjRepos\en\Code_Templates to make them visible only on one Delphi version.
Edit
As Sertac points out in the comments, Template libraries are related to project templates, not code templates. Leaving this answer in place because it may help people looking for ways to structure / share / split their project template repositories.
In Delphi XE2 you have a "Template libraries" option under the "Tools" menu. When you open that, you get this dialog:
The "Add" button allows you to add a folder, the "Properties" button allows you to view and manage the contents of that repository.
So it would seem to me that you can simply copy the template library, change it XE2 specific stuff, and then point XE2 to its own repository. Or you could do that only for the templates that require specific XE2 unit handling.

how to show the files thumbnails like windows explorer in delphi?

I use the TFileListBox control to show lists of files. But I wonder how to show the file thumbnails in the same way that Windows Explorer does?
You should try using the ShellControls components included in Delphi. (Note that David Heffernan sort of mentioned, and TLama made the initial specific suggestion in the first two comments to your question.) They're not installed by default in recent versions, so you'll have to install them yourself.
These instructions are for the version of Delphi you've indicated you're using (Delphi 2010) - they're the same basically for XE/XE2, except they're in the Samples\Delphi\VCL\ShellControls folder instead (and the Start entry contains XE or XE2 instead of 2010, of course).
Use Start->All Programs, navigate to the Embarcadero RAD Studio or Embarcadero Delphi 2010 item, expand it, and choose Demos. It's in the Win32 folder under DelphiWin32\VCLWin32\ShellControls. Open and build the vclshlctrls.dproj first, and then build and install the dclshlctrls.dproj. You'll need to add the folder above to your Project->Options in the search path for the compiler to be able to find them.
To install the components after building the second package, right-click on the project in the 'Project Manager' and choose 'Install' from the popup (context) menu. The 'Project Manager' in the default configuration is the area on the right edge of the screen that displays the files in the project. Remember, you need to build vclshlctrls first, and then install dclshlctrls, which is the design-time package.
You should then find the TShellListView, TShellTreeView, TShellComboBox, and TShellChangeNotifier components on your palette in the Samples category.
.thumb files are ordinary png files, just with a different file suffix.
Knowing this one can display them in a TImage.
First the .thumb extension needs to be registered as new file format.
For this include PngImage in your uses and call this:
MyImage.Picture.RegisterFileFormat('thumb', 'PNG based thumbnails', TPngImage);
Later you can display the thumb file you like like this:
MyImage.Picture.LoadFromFile('d:\Pictures\Pictures.thumb');
