Line 1120 of wingdi.h is
ASSERT(m_hObject == NULL); That means you are trying to load a second bitmap into a CBitmap object. You have to detach and delete the existing image before you can load a new one.
DeleteObject(MyBitmap.Detach());
MyBitmap.LoadBitmap(IDB_BITMAP);

Everybody knows the Microsoft forms 2.0 image control. I'm getting nuts with this.
I need to set the image file dynamically...but look at this.
m_imagecontrol.SetPicture(LPDISPATCH newValue);
I have a file dialog to browse the image, the question is:
how can I set the CFileDialog.GetFilename() in m_imagecontrol.SetPicture(LPDISPATCH newValue);
CFileDialog.GetFilename() is a CString, if there's a function to do this, please tell me before I kill myself.
thanks in advance pals

Try to look for IPicture usage. I think the LPDISPATCH param is a IPicture interface.

I'm attempting to add a gradient background to my applications main menu bar
to match what I've done to the toolbars. I've got as far as creating a
pattern brush from a bitmap and setting it as the menus background using
SetMenuInfo() but it is not being rendered correctly. The colour should go
from dark at the top to light at the bottom but what I've ended up with is
the darker half at the bottom going from dark to light and the lighter half
at the top going from dark to light. Its as if the origin for the brush has
negative coordinates. Can anybody suggest how to correct the origin of the
brush?

Hi 2 all,

As i m a student of Undergrad and got a project in VC++.Our peoject is about  multiLingual Translator.The basic objective is to take an input from the user and then translate it to someother language.So this is only done by Unicode. Since i donot have any exposure to Unicode  so i want ur help.How should this be carried out .I dont know how to store Unicode in Database ?
So anybody who knows this solution please contace me on my Yahoo id i.e luckylaeeq4u@yahoo.com. Thanx for reading my problem  . Hope some positive response from you Guys.
Bye and Take Care.

I want to do something like this, however wsprintf throws a compiler error. Is there another format function that I should use instead to do this?
BSTR path = NULL;
int num = 1;
path = SysAllocString(L"//errors/error[@id='%i']");
wsprintf(path, num);

int num = 1;

I realize that. I need to use a BSTR for the rest of what I am working on. Any other suggestions?

Do all formatting using LPTSTRs, then use the T2BSTR conversion macro to get your BSTR type.

Ummm, there is a problem ...
Aside from the BSTR != wchar_t*, what do you expect wsprintf to do ?
I mean it's used to take a format string (path) and create a result - you haven't specified a result string. Are you expecting it to modify path in place (it won't even with correct types) ?
From MSDN :
typedef OLECHAR * BSTR;
These strings are zero-terminated, and in most cases they can be treated just like OLECHAR* strings. However, you can query a BSTR for its length rather than scan it, so it can contain embedded null characters. The length is stored as a 32-bit integer at the memory location preceding the data in the string.
The 32-bit is placed before the BSTR value so you don't need to worry about it, just cast the BSTR to a wchar_t*.
e.g. (without error checking)
wchar_t res[500];
BSTR path = NULL;
int num = 1;
path = SysAllocString(L"//errors/error[@id='%i']");
wsprintf(res, (wchar_t*)path, num);
...cmk

You're misusing the BSTR. wsprintf() prints into a TCHAR array, but a BSTR is not an array.
BSTR path = NULL;
CString s;
int num = 1;
s.Format ( _T("//errors/error[@id='%i']"), num );
path = s.AllocSysString();If you can't/don't want to use CString, alloc a TCHAR buffer instead and make sure it's big enough, then use the T2BSTR conversion macro to convert it to a BSTR.
Check out this article[^] if you need more details on converting between string types.

I am working on a SDI project that calls a function SetModifiedFlag(), in my document file, if any value in my document file changes. That function is not part of my projects document file but seems to be a call to a function that exists in CDocument...(CDocument::SetModifiedFlag()). Can someone tell me what this function is? The function contains a boolean value, bModified. How can I access this value for reading, and resettng. Is this a typical way to test to see if any of your doc values have changed, etc. I am just not familiar with this and someone else developed this piece of code.
Thank You.
Jerry

In a straighforward MFC implementation, you can call SetModified() and the variable you mention is set to a 'true' value indicating data has changed. The framework would use that, or you would, when the user 'closes' your application and you would ordinarily pop up a warning that the document has changed, and ask user if he wants to save it before exiting your program. In an SDI instance, I think you would do the same thing on File|New or File|Open if the data had changed, so user does not lose data changes prior to loading a new document. When the document is saved, then the modified flag is reset to a 'false' value.

Hi All,
Now that MS VCToolkit (compiler and libraries from VC++ 7.x) is available as a free download from Microsoft, a natural question would be - is it possible at all to use it with DevStudio 6? It would be nice to be able to use the build environment... How about debug info compatibility and command line options compatibility? Did anybody try?
thanks!

Yes. Just set the paths to the new compiler before the paths to the VC6 compiler in the Executables section of the Directories tab in the Options.
yurig wrote:

The command line is compatible, so no problems there. Unfortunately, the VC6 debugger can't understand the VC7 debugging information, so you won't be able to debug any apps generated with it under VC6 - you'll need to use the new debugging tools.

Thanks Ryan! I was able to compile my project, and this is basically all I need at this point - just make sure it will compile.

MFC.
I do a skinning for a winapp written in mfc.
I have to change totally the bkcolor

Toolbar separators,
Static frames and 3D edit controls shadows which are still

P.S
Just Dont tell me I have to handle them on WM_PAINT

Hello,
I downloaded JBSocketServer1.zip and tried to compile it, however I got the following errors coming from mswsock.h and winsock2.h
Would you know why?
Thanks in advance.

Try including winsock2 before mswsock

No including winsock2 before mswsock did not help...
