Hey I've been trying to add this custom made indicator into my code but the problem is I can't find the indicator's parameters.
Here's what I've been trying to do:
void OnTick()
{
int RMI_Value1 = iCustom(NULL,0,"RMI",14,5);
Print(RMI_Value1);
}
Yet the output is always 0.
This link below is the source code of RMI.
https://pastebin.com/dJjvDZ7y
The indicators binds external parameters using SetIndexBuffer(), so it's going to be:
SetIndexBuffer(0,RMIBuffer);
SetIndexBuffer(1,PosBuffer);
SetIndexBuffer(2,NegBuffer);
The number of parameters is specified by IndicatorBuffers(). And its label is set by SetIndexLabel().

I am learning about fluid dynamics (and Haxe) and have come across this awesome project and thought I would try to extend to it to help me learn. A demo of the original project in action can be seen here.
So far, I have created a side menu of items containing different shapes. When the user clicks on one of the shapes, then, clicks onto the canvas, the image selected should be imprinted onto the dye. The user will then move the mouse and explore the art etc.
To try and achieve this I did the following:
import js.html.webgl.RenderingContext;
function imageSelection(): Void{
document.querySelector('.myscrollbar1').addEventListener('click', function() {
// twilight image clicked
closeNav();
reset();
var image:js.html.ImageElement = cast document.querySelector('img[src="images/twilight.jpg"]');
gl.current_context.texSubImage2D(cast fluid.dyeRenderTarget.writeToTexture, 0, Math.round(mouse.x), Math.round(mouse.y), RenderingContext.RGB, RenderingContext.UNSIGNED_BYTE, image);
TWILIGHT = true;
});
After this call, inside the update function, I have the following:
override function update( dt:Float ){
time = haxe.Timer.stamp() - initTime;
performanceMonitor.recordFrameTime(dt);
//Smaller number creates a bigger ripple, was 0.016
dt = 0.090;//#!
//Physics
//interaction
updateDyeShader.isMouseDown.set(isMouseDown && lastMousePointKnown);
mouseForceShader.isMouseDown.set(isMouseDown && lastMousePointKnown);
//step physics
fluid.step(dt);
particles.flowVelocityField = fluid.velocityRenderTarget.readFromTexture;
if(renderParticlesEnabled){
particles.step(dt);
}
//Below handles the cycling of colours once the mouse is moved and then the image should be disrupted into the set dye colours.
}
However, although the project builds, I can't seem to get the image imprinted onto the canvas. I have checked the console log and I can see the following error:
WebGL: INVALID_ENUM: texSubImage2D: invalid texture target
Is it safe to assume that my cast for the first param is not allowed?
I have read that the texture target is the first parameter and INVALID_ENUM in particular means that one of the gl.XXX parameters are just flat out wrong for that particular function.
Looking through to the file writeToTexture is declared as so: public var writeToTexture (default, null):GLTexture;. WriteToTexture is a wrapper around a regular webgl handle.
I am using Haxe version 3.2.1 and using Snow to build the project. WriteToTexture is defined inside HaxeToolkit\haxe\lib\gltoolbox\git\gltoolbox\render
writeToTexture in gltoolbox is a GLTexture. With snow and snow_web, this is defined in snow.modules.opengl.GL as:
typedef GLTexture = js.html.webgl.Texture;
So we're simply dealing with a js.html.webgl.Texture here, or WebGLTexture in native JS.
Which means that yes, this is definitely not a valid value for texSubImage2D()'s target, which is specified to take one of the gl.TEXTURE_* constants.
A GLenum specifying the binding point (target) of the active texture.
From this description it's obvious that the parameter isn't actually for the texture itself - it merely gives some info on how the active texture should be used.
The question then becomes how the "active" texture can be set. bindTexture() can be used for this.
I want to get the real "Trading Volume" for a specific Bar but the return value of volume function and iRealVolume function are both quiet different from what i am seeing on the chart when clicking the indicators of volume in the main page.
for example volume[0] should show the data of 290000000 but it shows 13000000 instead.
here is what i am doing to get the real volume of a bar.
double a = volume[0];
double b = iRealVolume(Symbol(), Period(),0);
i would like to know if any of you guys have a solution for my problem and your consideration is highly appreciated.
If I'm not mistaken, iRealVolume is indexed by a time series to do the same with volume call ArraySetAsSeries:
ArraySetAsSeries(volume, true);
I am using LoadRunner version 12.02 - Build 2739
Looking at an old, yet correct 'guide' shows that I have used the statements correctly (3rd Point, around 1/3rd of the way down the page, inside the code block - the atoi statement).
But I am still unable to convert the _count parameter to an int-Variable.
In the script, before the call is made;
web_reg_save_param(
"ParamName=rotaPeople",
"LB=someText",
"RB=\")",
"Ord=ALL",
LAST);
After the web call the save_param function is placed before, the output log shows;
Notify: Saving Parameter "ParamName=rotaPeople_count = 21".
Inside the script, after the call is made, and the count has been totaled;
lr_output_message("RP_C:%d",lr_eval_string("{rotaPeople_count}"));
lr_output_message("RP_C:%s",lr_eval_string("{rotaPeople_count}"));
peoplesCount = atoi(lr_eval_string("{rotaPeople_count}"));
lr_output_message("PC:%d",peoplesCount);
In the logs after the above executions are made;
Warning: The string 'rotaPeople_count' with parameter delimiters is not a parameter.
RP_C:110826864
Warning: The string 'rotaPeople_count' with parameter delimiters is not a parameter.
RP_C:{rotaPeople_count}
Warning: The string 'rotaPeople_count' with parameter delimiters is not a parameter.
PC:0
Anyone have any ideas?
Note: The Warning messages are expected
Note: Workaround: Used web_reg_save_param_regex() and created a regular expression. Using the returned _count parameter within a for-loop worked. Keeping question open, as the original problem still persists
The problem is that you use a soon to be deprecated API web_reg_save_param which does not support the ParamName syntax. In this API the second parameter is always the parameter name and therefore the correct use would be:
web_reg_save_param(
"rotaPeople",
"LB=someText",
"RB=\")",
"Ord=ALL",
LAST);
The proper API to use is web_reg_save_param_ex which does support the syntax you used so the call should look like:
web_reg_save_param_ex(
"ParamName=rotaPeople",
"LB=someText",
"RB=\")",
"Ord=ALL",
LAST);
Then the rest of your code should work properly.
I am not sure what you are doing but you might want to take a look at the somewhat unknown API lr_paramarr_random which will automatically pull a random value from the parameters array.
This should help you
web_reg_save_param(
"rotaPeople",
"LB=someText",
"RB=\")",
"Ord=ALL",
LAST);
lr_output_message("PC:%d",atoi(lr_eval_string("{rotaPeople_count}")));
You are using ord=all,see the run time data which value you want to capture,If you want to capture the 10th value please use ord=10,automatically this warning will remove from output log.
Example for capturing an array of dynamic values:
Action()
{
int i;
int ncount;
char ParamName[100];
web_set_sockets_option("SSL_VERSION", "TLS");
web_reg_save_param("trackingno","LB=;","RB= (NTN 0430)","search=All","ord=all",LAST);
web_submit_data("barcode.pl",
"Action=http://qtetools.rmtc.fedex.com/barcode/cgi-bin/barcode.pl",
"Method=POST",
"TargetFrame=",
"RecContentType=text/html",
"Referer=http://qtetools.rmtc.fedex.com/barcode/html/barcode.shtml",
"Snapshot=t2.inf",
"Mode=HTML",
ITEMDATA,
"Name=formcode", "Value=0430", ENDITEM,
"Name=count", "Value=10", ENDITEM,
"Name=narrow", "Value=2", ENDITEM,
LAST);
ncount= atoi(lr_eval_string("{trackingno_count}"));
for (i =1;i <= ncount;i++)
{
sprintf(ParamName, "{trackingno_%d}", i);
lr_output_message("Value of %s: %s",ParamName,lr_eval_string(ParamName));
}
return 0;
}
I want to call cv::integral() function, located at sumpixels.cpp .
I'm not using the integral image calculated for the square sum (3d argument - OutputArray _sqsum) , and would like to disable its calculation in order to save run time.
I'm not TOO familiar with the opencv environment.
Tried to call cv::integral() function with NULL as the 3d param - didn't work.
I entered the function (at sumpixels.cpp) and I saw there is this line:
if( _sqsum.needed() )
{
...
}
So I guess I can modify it manually to skip that if condition, but what would be the consequences of that? I see later the use of the parameter sqsum when calling IntegralFunc func method, what should I send to it then instead of that sqsum?
Thanks alot!
Eyal
Could you detail more precisely what didn't work when you set the 3d parameter as NULL ?
I debugged the code using OpenCV 2.4.2 and when the 3rd param is set to NULL _sqsum.needed() returns false which prevents the computation of the sqsum.
i have two volumes (.nrrd) of different qualities. the user can browse through the layers. if a key is pressed
i want to load the slice of the volume with better quality.
my volume is similar to this one: lesson 10 xtk
i've found:
volume.children[2].children[0].children[0].texture.file = "http://path/to/file.ext";
but if i apply some kind of file (.jpg, .dcm) nothing happens.
is this the right approach to change the slice to go inside the children and change the texture?
or shall i load the selected slice seperate as an object and apply it to the "lower-quality-volume" somehow?
edit:
this is what i tried so far (i get errors with dcms but not with jpgs):
if (event.keyCode == 83) { // "s"-button
volume.children[2].children[0].children[0].texture.file = "http://localhost:3000/112.jpg";
volume.children[2].children[0].children[0].modified();
r.render();
}
edit2: this is whats in my r.onShowtime = function() {}
volume.children[2].children[0].texture.file = 'http://localhost:3000/112.jpg';
volume.children[2].children[0].visible = true; // to activate the first layer
volume.children[2].children[0].modified();
console.log(volume.children[2].children[0].visible +" "+ volume.children[2].children[0].texture.file);
it outputs "true hostname/112.jpg"
when i inspect the .jpg in firebug the header is ok but the answer is "null"
when i inspect console.log(volume.children[2].children[0]); with firebug
.texture.file is set to hostname/112.jpg
when i go to "network" the .jpg has been transfered successfully
please notice that 112.jpg and level.jpg are the same. the first one is getting loaded in r.onShowtime and the other one is loaded at a keypressed event.
EDIT 3: volume.children[2].children[0] is of the type "X.slice", isn't it?
here is my approach: jsFiddle
and this is my actual issue and still not working: jsFiddle
Mhh..
I think a call to object.modified() is missing in the file setter (and in others setters from inject classes). Let's see when Haehn will come if he wants to change something internaly, but for the moment could you try to call it by yourself ?
You can try to add after the modification of texture :
volume.children[2].children[0].children[0].modified();
And if it doesn't work, in addition :
renderer.render();
Edit :
It's strange, I did a similar code and it did something. Can you please try something like that with opening your javascript console (Firefox, Chrome,... has one) and tell me the error you get ?
renderer.onShowtime = {
for (var i=0 ; i< volume.children[2].children.length ; i++) {
volume.children[2].children[i].texture.file="myimage.jpeg";
volume.children[2].children[i].modified();
}
}
It is important you call it in the onShowtime, because before the volume is not loaded, and so slicesX, slicesY... don't exist.
Edit2 :
Hey,
Thanks to the informations you added I think I've got the point ! In the render() method of our renderer3D there is a test on texture._dirty flag, that you cannot change from outside the framework. In addition the 1st rendering with a texture make that flag false, and loading a new texture doesn't seem to set that flag back to true in the current XTK. So, I think, we have to add it in the loader.load(texture, object) method. I'll make an issue on Github and see what Haehn thinks of it !
