Are you sure the font in the edit control has these characters? You can use the charmap utility to check.
Also guessing, did you create the control using CreateWindowW? Maybe the control is being all ASCII-y ?
Try making your project UNICODE (which you should anyway) and see if the problem goes away?

Hi,
first thanks for answer!
I create a dialog with the designer of VS and the CListCtrl i added from a toolbox!
And project is in unicode, other languages are showed normal!
"Are you sure the font in the edit control has these characters? You can use the charmap utility to check"
This can be a reason tor my problem, i use Tahoma as font for all my dialogs and i can't find any chinese character in charmap utility!!

I want to change the image of the toolbar button, that is, When I cilcked one tool bar button then I want to change the image of the button. So I have used the following code, but it saying some runtime error.
CToolBarCtrl &ctrl = m_wndToolBar.GetToolBarCtrl();
ctrl.AddBitmap(3,IDB_BITMAP3);
Pls provide me some solution,
|
|
|
|
|
try using LoadImages(). and what is this AddBitmap?

This function is used to add bitmap to imagelist associated with toolbar control.
Look at function SetImageList, and use it according to your need.
Images on toolbar shown according to imagelist associated with that toolbar control.

Hi,
You can set cold and hot images for the toolbar.
This is the sample code.
CImageList img;
img.Create(IDB_HOTTOOLBARS, 22, 0, RGB(128, 128, 128));
m_wndToolBars.GetToolBarCtrl().SetHotImageList(&img);
img.Detach();
img.Create(IDB_COLDTOOLBAR, 22, 0, RGB(255, 255, 255));
m_wndToolBars.GetToolBarCtrl().SetImageList(&img);
img.Detach();
Here m_wndToolBars is the CToolBar object.And IDB_HOTTOOLBARS and IDB_COLDTOOLBAR are the Bitmap imges in the resourse editor.

I am working on a 64 bit system (windows XP).I have a problem in launching an MFC dialog, that contains an active-x control (MSFlex Grid control).My project builds successfully without any errors.But when i try to launch this dialog, i get an error "Debug Assertion Failed".My Msflxgrd.ocx file is registered successfully.I don't understand where the problem is.Do let me know where the problem is.Please help me out ......
Thnx in advance.

|

|

This problem can arise if the dialog application is build for x64 and the flex grid is a 32 bit activeX.

Firstly, thnx for the reply.
I have a question, though...if i am working on a 64bit machine, then the active x control (Msflxgrd.ocx) will be for 64bit right?How is it possible that i can built a dialog for 64bit with 32 bit active x control?Is there anything else that is required to be done on my project settings or any other file that i am suppose to use or download.Please do lemme know. Thnk You.

It is not necessary that the flex grid is also 64 bit.
Even though the OS is 64 bit, you can create 32 bit binaries.
Basically a 64 bit binary cannot load any 32 bit modules (.dll, .ocx etc.)
Similarily 32 bit binaries cannot load 64 bit modules.
So make sure the dialog app and flexgrid have the same bitness.

I have checked my dialog app and flexgrid.Both are 64bit.
I don't just understand what the problem is.Please do let me know.

If you can give me the stack trace and the code in you InitDialog function I could try and find out.

I would like to see the code where the actual crash happens.
I'm guessing this is the code where the dialog or form view is being initialized.

Hi.....
Thnx for the reply.I have pasted the code below from dlgcore.cpp.The code fails at function CreateDlgIndirect.Do have a look.
If possible plse create an MFC Application in VS 2005 and insert an active x control (MS FLEX GRD) and execute it.i think you might get the error "Debug Assertion failed", while executing the dialog.to remind, my system is a 64bit system .Thnx once again.Please do let me know if you get to know the problem.
thnx.

Hello,
I have two programs that run well independently. One controls motion, the other is for viewing with a webcam. Each is intended for a human operator.
I have c++ source code for the camera program.
I do not have source code for the motion controller but I do have c++ source code for a dll plugin for the motion controller. The plugin has the necessary functions.
I would like to add a feature to the camera program so that it calls a function in the motion controller plugin and gets the returned value.
How can I define a function in the motion controller plugin so that it is callable from the camera program?
What is this scenario called and what keywords will help me search for information or examples?

Presuming you're using Visual C++...
You want to use __declspec(dllexport) to define functions that are exported from the DLL and are thus callable from any other program (including the camera program). The best way to use it is like this:
- Declare the DLL's exported functions in a header file (note - replace THIS_FILE_H with some text representing the headers actual filename - THIS_FILE_H represents 'ThisFile.h'):
#ifndef __THIS_FILE_H__
#define __THIS_FILE_H__
#ifndef PLUGIN_API
#define PLUGIN_API __declspec(dllimport)
#endif
PLUGIN_API int DoSomething(int aParameter);
#endif // __THIS_FILE_H__
- Add a .cpp file to the plugin DLL project which defines the functions (
DoSomething in this case) you've exported. You need the following two lines in that file, BEFORE you define any of the functions (note: replace 'ThisFile.h' with whatever you called the header file in the previous step):
#define PLUGIN_API __declspec(dllexport)
#include "ThisFile.h" - In the camera program,
#include the header in the .cpp file where you want to call the plugin's functions. You also need to link the plugin's export library (a .lib file) to the camera program.
This page[^] has several useful links.

Hello Stuart,
I posted a reply about half an hour ago and it has not shown up on the forum. So I am experimenting to see if I used the wrong procedure to reply.

Hello Stuart,
Well, I guess my first reply to you is lost in cyberspace. I'll try again.
BTW, I am using c++ in Visual Studio 2003.
The procedure that you suggest makes sense to me. I also used some of the keywords to find help topics. These also agreed. However, as you well know, the devil is in the details.
I am getting two warnings and cannot figure out why. Below are my brief header and cpp files and the warnings. What am I missing? Ignore the third warning.
I would not normally worry about a couple of warnings but I am also having errors compiling the calling program. So I am wondering what I need to specify to create the library here and how to import it at the calling end.
