Override the dialog's WM_ERASEBKGND so that the dialog background is not draw, and then in OnPaint draw the background you want.
Email me for more help.

I would so appreciate someone telling me what I'm failing to do in implementing splitter windows in an SDI app. A boiled down version of my program--default MFC SDI
app created with MSVS 6 app wizard, accepting all the defaults. Using ClassWizard, I add a new view class derived from CEditView. I then add a public CSplitterWnd
object to CMainFrame, and override the OnCreateClient() function with the following code (this code is taken more or less verbatim from the MFC sample DaoView):
BOOL CMainFrame::OnCreateClient(LPCREATESTRUCT lpcs, CCreateContext* pContext) {
if (!m_Splitter.CreateStatic(this, 1, 2)) {/*error handling*/}
if (!m_Splitter.CreateView(0, 0,
pContext->m_pNewViewClass, CSize(100, 50), pContext)) {/*error handling*/}
if (!m_Splitter.CreateView(0, 1,
RUNTIME_CLASS(CSplitEditView), CSize(0,0), pContext)) {/*error handling*/}
SetActiveView((CView*)m_Splitter.GetPane(0, 1));
return CFrameWnd::OnCreateClient(lpcs, pContext);
}
Program compiles fine, runs fine, but with no splitters. What am I leaving out? TIA

I just went through the same thing but as soon as I stopped calling the CFrameWnd::OnCreateClient function.
So instead of this:
return CFrameWnd::OnCreateClient(lpcs, pContext);
just try:
return TRUE;

Anyone have any suggestions on a simple, efficient way to remotely execute a program on another Windows NT machine from a local program and then have that program wait until the remote program finishes executing before continuing?
Thanks.

Can anyone here help me? I have gotten no response on the microsoft newsgroups. I want to use Working Set Tuner to optimize the rebasing of a number of DLLs, but I cannot find the WST tools on either the Sept. 1999 or the January 2000 Platform SDK (as far as I can tell, the Working Set Tuner is still supposed to be part of the PSDK---it's listed in the documentation). Can anyone tell me where to look?
Thanks,
Jonathan

Utilities like VADUMP and others are in the Platform SDK. Try searching on "Tuning the Working Set of Your Application" in the MSDN library or online. Look under "Performance Utilities" if you get that far.

I find documentation in the PSDK documentation, but I installed the whole PSDK and cannot find the executables WST.DLL, WSTUNE.EXE, WSTCAT.EXE, and WSTDUMP.EXE that the documentation refers to anywhere on my disk. Where do you find the executables?

I just received the following note from Robin Caron at MS Developer Support:
Hi Jonathan,
The release notes failed to indicate the the working set tuner is not
included with the Platform SDK because it did meet expectation for quality
and stability set for Windows 2000. If you have specific needs that were
answered by WST, please let me know and I'll do my best to find you
alternatives.
At a future time tools like working set tuner may get added back into the
Platform SDK.
Thank you for using the Platform SDK.

Hitting the ESC key calls CDialog::OnCancel() which closes the dialog. You just have to override OnCancel() and make the handler empty (don't call the base class OnCancel)
As for the static controls, add a handler for WM_CTLCOLOR, and when nCtlColor is CTLCOLOR_STATIC, return a null brush.

I'm using SHBrowseForFolder to create a browse dialog. The problem is when I change the
CD the CD volume label on the dialog is not refreshed. Even if I cancel out of the dialog and
then put in a new CD the label in the dialog still reflects the old CD.

I have a dialog derived from CFileDialog. I override OnLBSelChangedNotify. According to Microsoft documentation this should get called every time the selection changes, but it doesn't.
Any ideas or workarounds?

The following code will convert CR to a TAB for
jumping to the next control and only when the
OK button has focus CR will close the dialog.
void CMyDlg:: OnOK()
{
CWnd *pWnd = GetFocus();
ASSERT (pWnd);
if (IDOK == pWnd ->GetDlgCtrlID())
{
CDialog::OnOK();
}
else
{
NextDlgCtrl();
}
}

I think there may be difficulty in sending control characters to a dot matrix printer using the standard windows printing system, so I'm not sure you can just send character 15 to the printer....
Troy in our office mentioned that Windows supports a "plain text" printer driver that has limited capabilities (ie, might not support networkable connections etc.) but does allow you to send control codes.
I'm sure I read an article in MSDN about this topic, when reviewing material on how to write a printer driver (we flirted with writing a fax printer driver years and years ago), and remember reading a passage about this.
Sorry I don't have a more specific solution.

Your opinion please.
I want to create a menu system. In addition to starting and stopping apps, I want the menu to display what view each app is on.
In this example http://www.codeproject.com/threads/sendmsg.asp, Martin-Pierre Frenette shows how to pass data from one app to another. He uses the WM_COPYDATA.
In this example http://www.codeproject.com/dll/data_seg_share.asp, Phil Mcgahan shows how to do a similar thing using PostMessage and a shared data segment.
I have a lot of C experience, but only a few months of Visual C++. If you have experience in these types of matters, would you please express the pros and cons of each to me.
The basic question is WM_COPYDATA verses Shared Data Segment.
Thank you.
