Does anybody know how to create custom form sizes under Win9x. Under NT based versions of windows you can use the function Win32 API function AddForm().
Also does anybody know the correct way to retrieve the handle to a printer that you pass to AddForm(). At the moment I enumerate the available printers and then open the first one retrieved. This works but it seems like a bit of a bodge. Alternatively you can use AddPrinter() to get a handle but you need to know the name of an installed printer driver eg. Generic / Text Only will only work if already installed on the machine.
Thanks in advance for any help you can give.

Hi guys:
We are using COleDataSource for drag&drop between two CTreeView. That's ok.
Problem is multiple selection of items. How can we do this?
Thanx 4 all.

I'm currently writing a very simple HTML colour highlighting Rich Edit control extension (inheriting from CRichEditCtrl).
The control works perfectly in a debug build, behaving exactly as designed. However, in a release build no colourising takes place.
As a background the following code is used to get a particular line of text from the control to parse it:
CString strLineText;
int nRead = GetLine(nLineIndex, strLineText.GetBuffer(1024));
strLineText.ReleaseBuffer(nRead);
The line index is specified a sa parameter to the function. In the debug build this works fine. But in the release build, for some reason, GetLine returns 0 and strLineText is empty  This means that the rest of the code has no text to work on and so nothing is colourised.
In case you were wondering, yes the text is actually there, it's just that GetLine isn't supplying it.
The text has been added using a CString member variable i.e.:
m_strHtml = _T("Some really long html file that runs over several lines");
UpdateData(FALSE);
m_ctrlRichEdit.ParseAllLines();
I have also tried using ReplaceSel, SetWindowText, and I've even tried using the clipboard. All approaches have the same effect.
Any thoughts?

That is a funny one.
Is your GetLine method overridden? If so, check for obvious things like the method not being wrapped in #ifdef _DEBUG statements. Otherwise, try stepping into the statement (F11) to see exactly whats going on.
Failing that, I dunno, try using EM_GETLINE ??

I haven't overridden GetLine. The only things it handles are ENM_CHANGE (registered using SetEventMask in PresubclassWindow and OnCreate) and WM_CHAR.
Whilst trying to debug the problem I added several OutputDebugString calls in the OnChange handler. Bizarely enough if I output the window text in this call, the colourising succeeds becuase GetLine returns the correct text. I tried outputing smaller amounts of text thinking it may be timing related and found that it wouldn't work with anything less than half of the control text.
Even more bizarrely, following on from the timing thoughts, using Sleep or SetTimer to reparse the text after a specified time interval didn't work either. Even waiting for as long as 5 seconds.
It's really weird

I did a colorized java editor using a CRichEditCtrl a while back. It is of course just a dirty ol' hack , but if you want to have a look at it I can mail it to you.

You probably won't want to hear this... but I would advise you not to use the rich edit control for something complex like this (if it's part of a serious product that is).
We based our software product around this control and live to reget it.
It is quite buggy and as it is a part of the OS you don't have total control for distributing it with you App.

Hi all,
running my application under debug sometimes I receive this message "User Breakpoint called from code at 0x77f9f9df". When I run the application without debug the message is "...unknown software exception (0x0000003) in application at 0x77f9f9df".
The same error occurs when I press F12 running my application under debug.
My environment is Win2000.
Anyone know what it means, there is a solution?! Helpme please!
thanks and sorry for my poor english.

A 'user breakpoint' is an exception of your application. Probably, your exception should be an inconsistent pointer reference.
Debug your application, and concentrate your attention to your pointer values.

If I try to debug my application the error doesn't occurs!

Hi all,
From an exe called "whatever.exe" I call loadlibrary like this
HMODULE h_mod = LoadLibrary("mttool32.dll")
I receive a NULL value in h_mod. This is strange because whatever.exe resides in the same location as mttool32.dll and according to the docs LoadLibrary should search in the working/current directory.
I works fine calling it with an absolute path but I don't want to restrain my users to a specific location.
Any ideas why this is?

are you running your app from the dev environment (in debug or release mode) ? if you are the directory isnt what you think it is
just a thought

Hi Lauren,
In what way is the directory not what I think...? I tried to use LoadLibrary("mttool32.dll") both in Dubeg and Release mode and none of them works. But in both Debug and Release mode it works when supplying an absolute path... how come the directory is interpreted correctly just because the path is absolute?
I really need the relative path to function properly since people can install my software where ever they like... and having a hard coded path in my app is not a good thing... Well, good is mild; disaster I would call it.

Try pasting your DLL to the parent directory of both the Debug and the Release dirs.

Hi Tommy,
The working directory will not always be the directory where the exe exists. When you run it from Visual Studio, the working directory will be the parent directory of the debug/release directories.
Use GetModuleFileName to get the path of your exe, remove the filename, add your dll name and voila, everything is fine again

So I can't have the dll in the same directory as the exe calling the dll without using GetModuleFileName? Strange...
Thx for your help AI bot!

How can I get the following SQL statement to take a string value after FROM.
SqlString = "SELECT * "
"FROM ?????";
The string name is strFolderOpen and this will hold the name of the Access database to open.
Thanks, Aoife
|
|
|
|
|
assuming SqlString is a CString:
SqlString.Format("SELECT * FROM %s",strFolderOpen);
or have i misunderstood the question?

The proper way to close your application would be to sendmessage WM_CLOSE to the dialog.
Sorry to dissapoint you all with my lack of a witty or poignant signature.

Hi,
How can i Modify the "common" List Box text font size to a custom size ?
Thank's.

You just need to create a new font for the control. For example:
LOGFONT lf ;
CFont *pFont = GetDlgItem(IDC_LISTCONTROL)->GetFont() ;
if (pFont != NULL)
{
pFont->GetLogFont(&lf) ;
lf.lfHeight += 2 ;
}
else
{
}
m_Font.CreateFontIndirect(&lf) ;
GetDlgItem(IDC_LISTCONTROL)->SetFont(&m_Font) ;
