How can you stop the Tab key acting as an Enter key during text entry into a Edit Box.

If I enter text into the Edit Box and press the Tab key, then the program acts as if the Enter key was actioned.

I think the tab key was overrided for switching between controls in CWnd.

You could use CTRL D to see the sequence of tab sequence.

My opinion will be override the OnKeyUp of your CWnd for VK_TAB.

But probably there are simpler way to do.

See Michael Dunn's C++ FAQ on this site. It outlines a good method.

I am trying to create a program using the CreateProcessWithLogonW. I am working on a Windows 2000 Professional. The program compiles fine but when it tries to link it, it gives the following errors:

Linking...
CreateProcess.obj : error LNK2001: unresolved external symbol __imp__CreateProcessWithLogonW@44
Debug/CreateProcess.exe : fatal error LNK1120: 1 unresolved externals
Error executing link.exe.
Creating browse info file...

CreateProcess.exe - 2 error(s), 0 warning(s)

The code that I am trying to compile is as follows:

#define UNICODE
#define _WIN32_WINNT 0x0500
#define WINVER 0x0500

#include <windows.h>

#pragma comment(lib, "Advapi32")

int main(int argc, char* argv[])
{
STARTUPINFO si;
si.cb = sizeof(STARTUPINFO);

PROCESS_INFORMATION pi;

if (CreateProcessWithLogonW(L"UserName", L"Domain", L"password", LOGON_WITH_PROFILE, NULL, L"\"full file path\"", CREATE_DEFAULT_ERROR_MODE, NULL, L"\"current directory\"", (LPSTARTUPINFO)&si, (LPPROCESS_INFORMATION)&pi)) {
CloseHandle(pi.hThread);
CloseHandle(pi.hProcess);
}

return 0;
}

Changing Size Font and Vertical Scroll Bar

Hey all,

I got 2 questions.

1st one is how do you change the size of a CString? I have tired and I couldn't get it, here is what I have tried.

<br />
CFont font;<br />
   font.CreatePointFont(480, "Arial", &dc);<br />
<br />
<br />
   CString str("DEP");<br />
<br />
   CSize size = dc.GetTextExtent(str);<br />
<br />
	dc.DrawText(str, printArea, DT_NOPREFIX | DT_WORDBREAK);<br />
<br />

2nd question is how do you get a Veritcal Scroll Bar to work? I know how to add it to a Dialog, but can't get it to scroll.

Thanks for the help

Before a call to the device context functions, you need to select the graphics object(s) you need to work with; in your case, a CFont object. Write the following statements before and after a call to the DrawText(...) function respectively:

Before
CFont *pOldFont = dc.SelectObject(&font);

After
dc.SelectObject(pOldFont);

Using Excel data in VC++ 6.0

I am trying to access an Excel spreadheet in Visual C++ 6.0. I am using the XL5EN32.OLB library. However I keep getting errors, one of which is:

error C2440: 'type cast' : cannot convert from 'class Sheets' to 'class COleVariant'

I just wanted to be able to pull data out of a spreadsheet and use it in my program. There are problems with Ole. I thought you could define a sheet from the workbook object. However it does not allow me to do this. You have do get sheets from a workbook and a workbook from a file. But I can not do this, the return types don't match. I looked at MSDN article 179706

http://support.microsoft.com/default.aspx?scid=kb;EN-US;179706

It doesn't seem to work that way though. I don't know how they got the return types to match.

COleVariant fn;
CString f;
Application app;
Workbooks books;
Workbook book;
Range pRange;
Sheets sheets;
double Result;
COleVariant
covTrue((short)TRUE),
covFalse((short)FALSE),
covOptional((long)DISP_E_PARAMNOTFOUND, VT_ERROR);

app.CreateDispatch("Excel.Application");

app.SetVisible(covTrue);

books.Open(fn, covOptional, covOptional, covOptional, covOptional,
covOptional, covOptional, covOptional, covOptional,
covOptional, covOptional, covOptional);

sheets = book.Sheets(COleVariant((short)(1)));

There are some internal logic that you need to handle.

The way to correct this is.

LPDISPATCH lpDisp;
lpDisp = book.Sheets(COleVariant((short)(1)));

 ASSERT(lpDisp); //some checking
 sheets.AttachDispatch(lpDisp);

I have not tested it but it should be that kind of style down the road using AttachDispatch(...)

Try

//I am sure there are some elegant ways to do these

//have a test environment off hand for this. 

 LPVARIANT lpVar = (book.Sheets(COleVariant((short)(1)))).operator LPVARIANT( ); 

LPDISPATCH lpDispatch;

if(lpVar->vt == VT_DISPATCH)
{
 lpDispatch = lpVar->ppdispVal;
}
else
{
 //error
 ASSERT(NULL); 
}

sheets.AttachDispatch(lpDisp);

EndModalDialog?? Any Ideas

I have a modal dialog box that I would like to go modaless if a button is clicked on and then back to a modal state after the buttons action has ended.

I have tried EndModalDialog but with no success, does anyone know a command that can help me?

Re: EndModalDialog?? Any Ideas

Just call yourDialog.DoModal() for modal dialog.

and yourDialog.Show() for modeless.

There are plenty of tutorials on modeless dialog in codeproject.

I want the Dialog Box to be modal unless the button is clicked.

If they never click the button then the dialog box should just be
modal the entire time.

What I am trying to do is: if a user clicks on a button then it opens a doc/view window where they can make a choice that sends them back to the dialog box which would return to its modal state.

Thanks

I think Gary R. Wheeler suggestion is implementable.

Like

((YourParentDlg*)this->GetParent())->EnableWindow(FALSE);

Anyway, I think the logic behind is and should lie under you.

Probably the easiest way to do this is to have the dialog be modeless all of the time, and then simulate modality by having the dialog disable/enable the parent window as necessary.
