Hi all!
i have created a button control activeX MFC, and created property 'Text' , it same 'caption' of basic button.
however, after i compile, use on VB.net, that ok. But C++ application MFC, caption not change now, but when i move it on design dialog, it changed.
i do not understand it.
plz help me !!!
i debug with tstcont.exe, apss form (VB.net), C++ MFC (: error)
what solution for it!
thanks so much!!!

C++

BSTR CButtonViewCtrl::GetTex(void)
{
     AFX_MANAGA_STATE(AfxGetStaticModuleState());
     CString strResult;
     _buttonView.GetWindowText(strResult);
    return strResult.AllocSysString();
}

voidCButtonViewCtrl::SetTex(LPCTSTR newVal)
{
     AFX_MANAGA_STATE(AfxGetStaticModuleState());
     _buttonView.SetWindowText(newVal);
    SetModifiedFlag();
}

it's difficult to know, so code is normal
it's worked normal on VB.net/ testContainer,apps win form...
but, on application MFC... it will be change caption when we move button on design dialog

Nobody can help without to see your source code - please show what you have tried as far ...

dev C plus 22-Apr-13 5:26am

code is normal!
i also only do not understand, why is not working now with application MFC, while it's good with vb.net and test container

BSTR CButtonViewCtrl::GetTex(void)
{
AFX_MANAGA_STATE(AfxGetStaticModuleState());
CString strResult;
_buttonView.GetWindowText(strResult);
return strResult.AllocSysString();
}

voidCButtonViewCtrl::SetTex(LPCTSTR newVal)
{
AFX_MANAGA_STATE(AfxGetStaticModuleState());
_buttonView.SetWindowText(newVal);
SetModifiedFlag();
}

Solution 1

use different texts so you will see, that you see a different text value than, you want to see.

Check that you are using the right handle. Check the result and read the docs:

thanks you for this!
i have review on msdn and many forum... so much
so, i try it with more solution and bug is not yet fix

seperate the "layers" ie objects and code segments til you get a working skeleton. On that way you will find your bug.

oh! thanks for it
But, this a same code normal, and the problem is difficult to understand
now, i'm not yet fix it
is bored

KarstenK 23-Apr-13 3:13am

I am convinced that you have 2 or more texts, which are overlapping. So I use the keyword "layer". You need to fizzle it in separete parts....

dev C plus 23-Apr-13 3:58am

i don't think same to you
because, my project is started and i only had a object button inherit Class CButton
just, i have created one variable _mButton, and one property for it
so... to change Caption for it, i use API Get/SetWindowText() for function Get/Set
if any thing as you talk about with me... also, on vb.net, test container, it can't compile good also as now
thanks for help me
