In OnChar, the first parameter is a UINT. If you declare a char to be equal to that value, you can test for any key you like:
<br />
void CTestView::OnChar(UINT nChar, UINT nRepCnt, UINT nFlags)<br />
{<br />
char c = nChar;<br />
CString s(c);<br />
AfxMessageBox(s);<br />
}<br />
This will bring up any key you press in a message box.
The conversion from int to char is implicit.

I'll likely take a stab using OnKeyDown
WM_KEYDOWN sends a VK code, but WM_CHAR sends the actual char, from what I can tell. I am using MFC7 ( and that means adding message handlers manually BTW  ), but I think the wParam value in WM_CHAR will work the same as the UINT in my code sample.

I am sure WM_CHAR will work easily. I always try to avoid PreTranslateMessage if I can.

Nope... I am supposed to have my CD's back for my enterprise/architect back tomorrow by 4 pm. Had to have my brother overnight it to me Saturday. I'm looking forward to, it been rough not being able to do certain things on this SE version. Been challenging though.

The VK code for '6' is the same as the ASCII char value; to check for the Shift key being pressed you could GetKeyState() function (GetKeyState(VK_SHIFT)).

I am just trying to launch a simple thread. Code compiled with no error but the thread function is simply NOT invoked for some reason!
And i checked the thread handle - hThread - It's NOT NULL!! I cant see why it doesnt invoke the thread function!
Here's the code fragment:
// TryThreading.cpp : Defines the entry point for the console application.
//
#include "stdafx.h"
#include <iostream.h>
#include <windows.h>
DWORD WINAPI SomeThreadFunc(void* pParam)
{
DWORD dwRetCode;
cout << "Thread Func invoked!" << endl;
if(pParam!=NULL)
{
cout << "nNum= " << * (int*) pParam << endl;
}
return dwRetCode;
}
int main(int argc, char* argv[])
{
HANDLE hThread = NULL;
int nNum = 0;
unsigned long nID = 0;
hThread = ::CreateThread(
NULL,
0,
(LPTHREAD_START_ROUTINE) SomeThreadFunc,
(void*) &nNum,
0,
&nID
);
CloseHandle(hThread);
return 0;
}
HelP!

Your primary thread returns from main() right away, and that makes the whole process close. The thread is being started, the app just closes right away so you never see the output from the thread.

I don't know if it is possible in ADO, you need to get the IJetCompact interface and call its Compact method. It is dead easy using OLE DB:
<br />
CDataSource src;<br />
<br />
CComPtr<IJetCompact> spCompact;<br />
hr = src.m_spInit->QueryInterface(IID_IJetCompact, (void **) &spCompact);<br />
<br />
CDBPropSet init(DBPROPSET_DBINIT);<br />
init.AddProperty(DBPROP_INIT_DATASOURCE, "compacted.mdb");<br />
<br />
hr = spCompact->Compact(1, &init);<br />

You can use CDaoDatabase from MFC to do it easily enough. Not sure about ADO though

This is probably a stupid question (I haven't had much sleep in the past 3 days).
How can I tell Visual C++ to perform an extra step when compiling each .cpp file. What I want to do is basically what BoundsChecker does when you perform a compile. You see "compiling something.cpp" followed by a line reading "instrumenting something.cpp".
I know about custom build steps but I can't seem to get this to do what I want???

Hi All.. I have a global variable CArray < struct, struct&> a; declared in the same place as theApp global variable get declared.
I know if I want to use the global variable include in the other .cpp files, I have to call that global in such way
extern CArray<struct,struct&> a;
Then I Rebuild the project, Iand got linking error...
[code]
error LNK2001: unresolved external symbol "class CArray<struct dishinfo,struct="" dishinfo="" &=""> theMenu" (?theMenu@@3V?$CArray@UDishInfo@@AAU1@@@A)
Debug/ResturantSystem.exe : fatal error LNK1120: 1 unresolved externals
[/code]
why do i get error??

First of all, to fix this problem, declare the variable extern in your stdafx.h, and declare it in stdafx.cpp. Voila, visible everywhere.
Secondly, DON'T do this. Global variables are a terrible idea. If you must, then at least put them in a namespace. It's far better to make them members of your main window and access them that way.
Finally, you should investigate std::vector, check out the STL articles here on CP. CArray is really a terrible product, and is generally used by people who either don't know about the STL, or are put off by the awful docs in the MSDN. I've solved problem a, and the articles on this site will fix problem b. I think you'll be surprised how much nicer/powerful it is than the stuff that MFC ships.

whats wrong with my string?
I am trying to find a record in a database where one parameter is partially given ( LIKE 'm_val'). I don't get any database errors, but no info either.
CString m_cat, m_val;
// Build the SQL statement
SqlString = "SELECT * "
"FROM new WHERE cat='";
SqlString += m_cat;
SqlString += "' AND filename LIKE '";
SqlString += m_val;
SqlString += "*'";
Any helps really appreciated

I believe the wildcard character is %, that is, I know % works, but I've never tried *. Do your values start with m_val, the ones you expect to find ? Are they in the table called 'new', and in the 'filename' column ?
I find the best way to isolate this sort of problem is to build the query. Do a select *, a select cat, a select * where cat equals a known to be present value, etc.
