I need a ComboBox smaller than the standard minimum size that VC7 offers. Is this possible with CComboBox?

Can you not edit the .RC file manually, bypassing the resource editor?

Yes, but if I change the size there the list of the combo is resized. I need a combo with the edit control very small (hight very small).

You could try making it variable-height owner-draw, and implementing the measure item stuff, although of course you might also need to change the font it's using.

Hi,
in case this is still relevant:
i encountered the same problem and wish to trade my solution in return to your advice;).
to control the edit box height, i simply changed the combobox font size. e.g. (12==font height in points):
<code>CFont font;
LOGFONT lf;
font.CreateFont(12, 0, 0, 0, FW_NORMAL, FALSE,
FALSE, 0, ANSI_CHARSET, OUT_DEFAULT_PRECIS, CLIP_DEFAULT_PRECIS,
DEFAULT_QUALITY,
DEFAULT_PITCH | FF_SWISS, "Arial");
font.GetLogFont(&lf);
m_newFont.CreateFontIndirect(&lf);
m_ccombobox.Create(WS_CHILD | WS_VSCROLL |CBS_DROPDOWN
, rect, this, 0);
m_ccombobox.SetFont(&m_newFont); </code>
and now for my question: how do you get the size the rectangle wrapping the edit box + the arrow box?
thank you.

Thankyou for the solution but I already found something else to do. Unfortunately, both my solution and yours have the following problem: If the size is smaller than 12 the text in the combo is no longer entierly visible.
As for your question...I am not sure that I understand well but a quick solution would be GetClientRect(&rect).

Shalom,
sorry for insisting, but the text size is fully visible (i tried 10pt, 8 pt. hell even 6pt.), though at some point a microscope should be attached to the application. you may have some fixed list box style still present at your app.
as for your suggestion: though it is this which is self-evident that is frequently ignored, that is not the case this time. the problem is that i keep on getting the same combo client size, no matter what the actual visible client size is.
Thank you for your quick reply.

i used the following and got stuck after the recset.GetFieldValue("Address ID",sID);
recset.GetFieldValue("Last Name",sLastname);
coz nt sure how to make my edit box display the data of Address ID and Last name.
the code goes:
void CAccessdbDlg::OnButton2()
{
CDatabase database;
CString SqlString;
CString sID, sLastname;
CString sDriver = "MICROSOFT ACCESS DRIVER (*.mdb)";
CString sDsn;
CString sFile = "e:\\fyp_2003\\database_sample.mdb";
// Build ODBC connection string
sDsn.Format("ODBC;DRIVER={%s};DSN='';DBQ=%s",sDriver,sFile);
TRY
{
// Open the database
database.Open(NULL,false,false,sDsn);
// Allocate the recordset
CRecordset recset( &database );
// Build the SQL statement
SqlString = "SELECT Address ID, Last Name "
"FROM Categories";
// Execute the query
recset.Open(CRecordset::forwardOnly,SqlString,CRecordset::readOnly);
// Copy each column into a variable
recset.GetFieldValue("Address ID",sID);
recset.GetFieldValue("Last Name",sLastname);
????????????
database.Close();
}
CATCH(CDBException, e)
{
// If a database exception occured, show error msg
AfxMessageBox("Database error: "+e->m_strError);
}
END_CATCH;
}
and is this code correct?

Now you simply need to call the SetWindowText(sLastname) method of one of the edit control variables.

like this:m_str_lastname.SetWindowText(sLastname);?

Yes, assuming m_str_lastname is a CEdit variable.

Database error: Syntex error (missing operator)in query expression "Address ID"
and erm I din add code in Oninit dialog. Thanx for ur help!

That's why it is considered a bad idea to embed spaces into field names.
SqlString = "SELECT [Address ID], [Last Name] FROM Categories";

Is there an easy way to modify the VS_VERSIONINFO resource in a Win32 EXE. We currently open the file, search for the unicode string VS_VERSIONINFO, assume thats the start of the resource in the EXE and overwrite the required fields. This method seems a bit flakey as you need to reserve the correct number of characters for each string (file version, file description etc.) when the resource is defined. Also the structure seems to change according to the length of the strings which I think is due to 32bit boundaries. Can anybody recommend better method?

you can use some resource editor tools for doing this activity.
I would recomment 'ResHack'. Search and download. A very handy tool.

No can do. The programs are stamped with the current version number as part of our product generation procedure which involves updating 400+ programs. I was hoping there were API calls available or that someone had written a class to do it. Thanks for trying...

Forgive if I am failing to understand the situation properly but hacking the win32 executable seems like dangerous way of adjusting the VS_VERSIONINFO. Would it not be better remove all the existing VS_VERSIONINFO resources from your source code, and then have a separate .rc file that only contains your up-to-date VS_VERSIONINFO. Each compoenent can then be compiled with the same instance of the VS_VERSIONINFO resource and the need to hack the executables has gone.

Is there a way to delete a complete folder (short of finding all files, deleting them individually, then delete the folder)?
I can assume that I have Delete access, and the files are no longer used, and that there are no sub folders.

RemoveDirectory() deletes a folder, but the folder has to be empty. This code should do the trick :
void DeleteFolder(const CString & strFolder)
{
CFileFind finder;
if (finder.FindFile())
{
while (finder.FindNextFile())
{
if (!finder.IsDots())
{
if (finder.IsDirectory())
{
// Folder - recursively delete it
DeleteFolder(finder.GetFilePath());
}
else
{
// File - delete it
DeleteFile(finder.GetFilePath());
}
}
}
}
// And delete the folder
RemoveDirectory(strFolder);
}

Hi,
It's possible to use a WebService as a client from a Visual C++ 6.0 application ? Or I'm force to make the client install the .net framework and make an .net COM Component that will communicate with the old VC++ application ?

Hi I have the following situation:
SetWindowLong(hWnd,GWL_WNDPROC,(LONG)MyOwnWndProc);
MyOwnWndProc is a member function of a class I've made. Now I was wondering if it's possible to somehow convert a pointer to the function or something to a LONG. In its current state this won't compile. I've already tried making a class member pointer, and tried to convert that to a LONG, but alas no go.
And no, I don't want to use a non-class function. I really need to know if it's possible with a class function.
Many thanks in advance,
DanglingDude

Its possible with class member functions.
Try this
LRESULT CALLBACK YourClass::MyOwnWndProc(HWND hWnd, UINT msg,
WPARAM wParam,
LPARAM lParam)
{
}
and then use
SetWindowLong(hWnd,GWL_WNDPROC,(LONG)MyOwnWndProc);
