What are you trying to do ? Please, post some relevant code. Did you try debugging to see what is going on ?

Actually in my project I use 6 dialog. In one of my dialog I need to place CTreeCtrl. I created variable name for the control and when I run the program in debug mode, it shows Debug Assertion error like the above.
When I try to debug further, I just got struck up at the first line of the DoDataExchange and this is very strange to me.
If I debug further it shows error in the dlgdata.cpp file and m_hWnd is showing that "expression cannot be evaluated". I found that the error is occured when I set (true) the properties "Has Lines", "Has Buttons" and "Lines at root" of CTreeCtrl. Please help me.

I created the variable using the wizard. When I try to show the dialog the error occurs.

How are you trying to do that ? Please post some usefull code (using the "code block" tag).

You probably deleted a control after having created a control variable for it? May be DDX is trying to operate on a control that doesn't exist. Have you tried disabling that first line and compiling?

If I comment then it shows on the next line.

Why don't you try to analyse the problem? Have you verified that ALL the IDs that are listed in the DDX function actually exist?

This is an indicator that you have a call to DDX_Control() for a non-existant control. Why not comment them all out and note the result?

The debugger is not working?

When I run a project, it shows exception. If I debug using F11 or F10, I can't go beyond that line where it shows exception. I can't see Disassembly also. What to do? Here is the code:
void TestAI::EnableShaders()
{
dtCore::ShaderManager& sm = dtCore::ShaderManager::GetInstance();
dtCore::ShaderProgram* sp = sm.FindShaderPrototype("TestShader", "TestShader");
if(sp != NULL)
{
sm.AssignShaderFromPrototype(*sp, *m_Obj->GetOSGNode());
mEnabled = true;
}
}
Exception occurs at the following line:
sm.AssignShaderFromPrototype(*sp, *m_Obj->GetOSGNode());
Here is the contents of Output Window.
First-chance exception at 0x00407336 in GUI.exe: 0xC0000005: Access violation reading location 0x00000020.
Unhandled exception at 0x00407336 in GUI.exe: 0xC0000005: Access violation reading location 0x00000020.
How to resolve these exception?

Do you check if your pointers are properly initialized. BTW what happens inside GetOSGNode function. Did you try to get into this while debugging?
Somethings seem HARD to do, until we know how to do them.

Yes. There's the problem. If I press F11 or F10, I can't go beyond that line(Exception Dialog is shown). What to do?
|
|
|
|
|
Did you use a debugger to see if everything is correct ? What is the value of m_Obj ?
|
|
|
|
|
Yes. It contains a meaningful value. It contains the following:
osg::ref_ptr<dtCore::Object> {_ptr=0x018285f8 } osg::ref_ptr<dtCore::Object>

Setting a breakpoint on that line, what is the value of sm, sp, and m_Obj?

Is there any function to do the following operation in CPP?
Round(3.4) = 3
Round(3.5) = 4
|
|
|
|
|
ceil() function?
ceil( 3.4 + 0.5 ) = 3;<br />
ceil( 3.5 + 0.5 ) = 4;
