On the picture control ,I mean to move the rectangle through the mousemove.
how to make it? the picture control contains a picture and a small rectangle is on it.

If you use of CStatic you can derived your class of it and then declare WM_MOUSEMONE on it or you cna do it of your main class.

with this code all is blocked if i remove the item "Progress->SetPos(percent);" all go ok but without progress bar moving.

You need to put your lenghty processing in a separate thread. Here[^] is an excellent article that will get you started about threading.

Hi i have created a Dialog which contains the two buttons OK and CANCEL . But when i resize the dialog these button stick to their original position and does not change . I want these buttons to be on Botton Right Corner of my dialog . In my code i have done this
.
AddAnchor (IDC_HPCR_WO_OK ,BOTTOM_CENTER );
AddAnchor (IDC_HPCR_WO_CANCEL ,BOTTOM_LEFT );
Please provide any comments on this
|
|
|
|
|
Which library are you using, because there's no such support as AddAnchor in the MFC ?
|
|
|
|

Are you using CResizableDialog[^]? You could use the message board at the bottom of the article to ask your query. The author of the class himself may respond to you in that case.

Hi ,
Yes I am using CResizingDialog . Now what i did is i have writte a message handler
MESSAGE_HANDLER( WM_SIZE, OnSize )
but i didnt provide its implementation. My class is derived from CResizingDialog . Now buttons are changing their position as i required. But still not understood how it is working. Is it calling CResizingDialog :: OnSize () in this case ..?

Hi All
How can i set dialog size at the run time?Plz help me
|

If you plan to have controls on your dialog and resize or move them based on the size of the dialog you may want to use a layout library like this one: CResizableDialog[^]

Have you looked at SetWindowPos() or MoveWindow()?

I've got an old project writetd in vc++ on VS 7.1. When I opened it on Visual Studio 2008 it was correctly converted and worked. Now i needed to use a part of this old code in the new project created on VS2008. Everything work exepct a part of old code:
int CDGabinetDlg::DefineGrammar(const char* fn)
{
int rc;
SM_MSG reply;
TCHAR lpBuffer[256];
GetCurrentDirectory(256, lpBuffer);
string filename(lpBuffer);
filename+="\\";
filename+=fn;
return rc;
}
I've get an error in this part:
string filename(lpBuffer);
This is an error what i get.
error C2664: 'std::basic_string<_Elem,_Traits,_Ax>::basic_string(const std::allocator<_Ty> &)' : cannot convert parameter 1 from 'TCHAR [256]' to 'const std::allocator<_Ty>

The difference between VC7 and VC8 (related to your error I mean) is that in VC2008, UNICODE is defined by default. If you want to better understand what that means, I suggest this article[^].
In your code snippet, you are not being consistent neither: sometimes you are using a char arrays, sometimes a TCHAR array. So, either you do not care at all about unicode and only use char array, or you care about UNICODE and use TCHAR arrays everywhere. But using both is ugly.
On the other hand, std::string do not support wide characters, so that's why you have the compilation error. For that part, if you want to support unicode builds, I suggest you define your own type:
#if defined _UNICODE || defined UNICODE
typedef std::wstring TMyString;
#else
typedef std::string TMyString;
#endif
This way, you'll be independant of the unicode settings.

Hey, I wanted to know that whether it is safe to use ADO in a DLL? The reason I'm asking this is that, to use ADO we need to initialize COM right? So calling CoInitialize in a DLL, is it okay?

Ahmed Manzoor wrote: we need to initialize COM right? So calling CoInitialize in a DLL, is it okay?
Yes. You do it and the matching uninitialize in DLLMain for every Process and Thread attach/detach message.
From the documentation:
Because there is no way to control the order in which in-process servers are loaded or unloaded, do not call CoInitialize, CoInitializeEx, or CoUninitialize from the DllMain function.

What do you mean? Is it safe? Will there be any malfunction?

Ahmed Manzoor wrote: Will there be any malfunction?
That depends on you, your analysis of your scenario and developing a correct solution. Make sure you read the documentation I provided a link to.
The best scenario is the host process has already handled COM initialization. If that isn't happening then you have a less than perfect scenario. Make sure you understand the ramifications and develop the proper error handling code for the potential scenarios that could occur based on your hosting scenario.
My fault, I should have mentioned that your scenario can also call for dealing with the initialization in other exports of your DLL rather than DLLMain. The problem with that is you need to account for the messages you get passed in DLLMain so that you know which event is happening. It's really up to you to figure all this out based on your project details.

Well now, I guess I would have to use another solution.
Thanks anyways

GetDlgItemText(id)->EnableWindow(FALSE) is not working in windows vista OS when user admin is off.I want to disable a groupbox in vista OS.
|
|
|
|
|
Do you want to disable the group box window? Why? After all its a static control
Or the controls within it?
You need to google first, if you have "It's urgent please" mentioned in your question.

You may perform the processing in a worker thread while displaying the wait message in the main (GUI) one, see [^].
