Do you mean it was written using managed code? Then no, you can't use VC 6.
If you mean it was written in native code using VS.NET, then you'll have to change the code so it doesn't use classes that were added after VC 6.

The CBitmapButton has a SizeToContent method which resizes the button to fit the size of the bitmap, I am looking for a way to resize a CButton to fit the size of the label.
Thanks

I know how to display a CFormView object by calling it from another view. I need, however, to display a form from an "empty" MDI main frame. The application also contains other types of views.
For example, I would like the user to start the application and then open a data file. The data will then be displayed graphically and used to populate a form.
What is the best way to show a form from the main frame window?
Thanks in advance for your help.

See the second question here.

No to both.

Not sure if Gdiplus has this feature but i would like to zoom or have an appearance of zooming. I have an MFC application that views .jpg images. When the image appears on my screen i place a cross bar reticle like

I am attempting to do two things.
1. Zoom on the area in the middle of the above reticle
2. Based on a mouse click of any area, magnify or zoom that spot
Anyone with any experience in this area?

Besides the fact that strcpy is win32 and StrCpy is MFC, what would vary the use of one over the other?
I have an MFC dialog application and if i use StrCpy, it says undeclared. If i use strcpy, i have no problems...
Can anyone shed some light on the uses of the two. Am i maybe missing an include file?
|
|
|
|
|
StrCpy is declared in shlwapi.h
Why is common sense not common?
Never argue with an idiot. They will drag you down to their level where they are an expert.

Hi,
I would say look at this link -

strcpy is a CRT function. StrCpy is a Win32 API function.

If you are writing an app that doesn't use the MS CRT (such as an ATL project built with _ATL_MIN_CRT) then the shlwapi version is a suitable replacement for the CRT version.

Why is one better than the other?
One is MFC. If you use MFC Code throughout, yo can hope that when MFC64 is fully ported, that your code will recompile with minimum fuss at 64 bit level. That hope would not be nescessarily there if you use win32 Code. conversely, if you use win32 code throughout, you may hope that it will sucessfully compile to 32 bit code on a 64 bit compiler, you have no hope of that if you use MFC Code. In Short, it is all a matter of what you hope for the future. The worst case scenario is of course what all of us do most of the time, and that is mixing up the calls. Doing that means that our code will fail to compile as sooa as the compiler changes.
The question is NOT as foolish as the first respondent would make us believe. Let him throw the First Stone...

 I write a application in form "Dialog" using Menus:
Option
* TurnMusic
I want that : when user click left mouse on "TurnMusic" menu,
a checked sign is displayed on that.
I write this code :
void CMenusDlg::OnUpdateOptionTurnMusic(CCmdUI* pCmdUI)
{
// TODO: Add your command update UI handler code here
pCmdUI->SetCheck(TRUE);
MessageBox("Checked !","Try Menus",MB_OK);
}
but:
when the program is runned, the checked sign is not displayed and MessageBox is excuted ofcourse!
If i write that Application in form SDI then checked sign is displayed normally.
this is occured similarly when i using hotkey in menu
(or is called : Accelerator)
Why ???
now, i want to write my Application in form "Dialog"
How must i do ?
Could you help me, please !!!

Hello,
I am a C#/VB programmer. I am trying to fix something that someone else wrote. There is a variable of type _variant_t. I need to take that value, and split it into 2 smaller variants. I am having problems doing this. If anyone can point me in the right direction, I would appreciate it. Here is the variable, "v", that I need to split into 2 variants.
//--------------------------------------------------------
// "m_pResponseBuf->BufPtr()" is a pointer to the text in
// a Response object.
//--------------------------------------------------------
_variant_t v( m_pResponseBuf->BufPtr() );
m_Response->Write( v );
How would I take a portion of "v" and put the results into another variant?
Thanks
Danny

A portion of v, from what you said, would then be a part of a string. To do string operations you can transfer the string into some more usable string object, do the operation you want then transfer the result into a variant.
Usually a string contained in a variant is of type _bstr_t, so you can do:
CString myString = (LPCTSTR)(_bstr_t)v;
//Do operation on myString
//Back into variant.
_variant_t v2( (LPCTSTR)myString );

Hello and thanks for the response. Is CString only for MFC apps? I read that somewhere. This dll I am working on is does not use MFC. I'll see if I can do something similar to this, which probably doesn't work, but I'll give it a shot.
std::string myString = (_bstr_t)v;
myString = myString.substr(0,1000);
_variant_t v2( (_bstr_t)myString );
Thanks!!
