I think you missed completemy the principle of object oriented programming and classes. I suggest you buy a good book or find a good tutorial (sorry, don't have any link) that will explain you what a class is and how to use it.
I don't want to sound offensive but I think you lack quite a lot of necessary informations about that subject and it is something too large to explain here.

The standard solution to this problem is to use "Double Buffering". There are heaps of articles on the subject.

Try using double buffering by drawing directly into memory.
After you finish drawing into memory you can transfer the contents of memdc back to your drawing area.
For this you will have to follow the following steps:
Just a sample...
CDC dc;
dc.Attach(this->GetDC()->m_hDC);
CDC memDC;
memDC.CreateCompatibleDC(&dc);
CBitmap memBmp;
memBmp.CreateCompatibleBitmap(&dc, 100, 100);
CBitmap *oldBmp = memDC.SelectObject(&memBmp);
dc.BitBlt(0, 0, 100, 100, &memDC, 0, 0, SRCCOPY);
memDC.SelectObject(oldBmp);
dc.Detach();
This is just a sample of double buffering. This will prevent flickering.
Happy programming

Hello.
Include the GDI+ headers in your source file mahadlgDlg.cpp
(AFTER #include <stdafx.h>)
I.e:
using namespace Gdiplus;
#include "GdiPlusBitmap.h"
#include "GdiPlusHeaders.h"
And
#pragma comment(lib, "gdiplus.lib")
That should do the trick.

yes!, why not

Since above class are defined under namespace Gdiplus, so you have to make call for

Hi,

What event should i handle? How to do this?

you have to associate the file extention with your program... for that you have to change entry in HKEY_CLASSES_ROOT in registry

Hi,
once i associate the the file extension, which function will be called if i open the file in explorer?
I mean, for example, my program is Program.exe, and the file is file.zzz. I associate the files *.zzz to my program, and if i open it in explorer, which function in my program will it be called?? OnOpen() etc?? Do i have to add an event handler?
THanks,
Usman

To complete the answer of Alok, in fact what really happen is that your program is called with the name of the file passed as command line argument. But, like Alok said, if it is a SDI or MDI app, the framework will handle all the job for you (it will call automatically the serialize methods thus loading the file). But of course, you have to implement the loading,saving of data in the serialize handlers.

hi,every one!
i want to change the companyname in my .exe file dynamicly,how to do?
there is a sample at http://www.codeproject.com/samples/UpdateVersion.asp, but it
does not deal with it.who can help me?thanks a lot!
|

I didn't get your question exactly. if you are trying to change the title of the application take the handle of the dialog and using SetWindowText() function you can change the name of the exe.
give me some more information about your problem.

The sample u mentioned has got complete code for changing the CompanyName. I have used this code myself. You just need to understand it fully before using and yes, dont forget to compile your application as unicode to do this. It wont work without that. I am just pasting a snippet of code here from the same article which does this.
CString strSubBlock;
LPTSTR pValueBuffer;
strSubBlock.Format(_T("\\StringFileInfo\\%04x%04x\\CompanyName"),
lpTranslate->wLanguage,
lpTranslate->wCodePage);
VerQueryValue(lpBuffer, (LPTSTR) ((LPCTSTR) strSubBlock),
(LPVOID *) &pValueBuffer, &uTemp);
ZeroMemory(pValueBuffer, _tcslen(pValueBuffer) * sizeof(TCHAR));
_tcscpy(pValueBuffer, _T("My Company, Inc."));
And yes, this Article is by one of the most respected members here. Mr. David Crow![Rose | [Rose]](https://codeproject.global.ssl.fastly.net/script/Forums/Images/rose.gif)

Thank you,Aamir Butt!
Yes,i use like that you write, but how can i use UpdateResource function whit the variable 'pValueBuffer'?
This is my code:
CString strSubBlock;
LPTSTR pValueBuffer;
strSubBlock.Format(_T("\\StringFileInfo\\%04x%04x\\FileDescription"),
lpTranslate->wLanguage,lpTranslate->wCodePage);
VerQueryValue(lpBuffer, (LPTSTR) ((LPCTSTR) strSubBlock),
(LPVOID *) &pValueBuffer, &uTemp);
ZeroMemory(pValueBuffer, _tcslen(pValueBuffer) * sizeof(TCHAR));
_tcscpy(pValueBuffer, _T("My Company, Inc."));
if (UpdateResource(hResource, RT_VERSION, MAKEINTRESOURCE(VS_VERSION_INFO), lpTranslate->wLanguage, lpBuffer, dwSize) != FALSE)
{
if (EndUpdateResource(hResource, FALSE) == FALSE)
dwResult = GetLastError();
}
else
dwResult = GetLastError();
But it does not replace the original companyname with "My Company, Inc." finally,perhaps where is wrong, can you help me? thanks a lot!
