Can a VC++ 6 Custom AppWizard produce multiple sets of output files?

If your query was something like SELECT name,address,phone FROM table WHERE name LIKE 'TER*' then you can simply change it to SELECT COUNT(*) FROM table WHERE name LIKE 'TER*' to get the number of rows returned. Is that anywhere near what you are after?

Re: Need ODBC help

Perhaps a solution, but not really the one I was looking for. I'm also a PHP coder, and I'm used to work with MySQL, which has an Api called mysql_num_rows, which also returns the SELECT row count. There is a function for ODBC, too, called odbc_num_rows, but this one does only work with some ODBC drivers (the Microsft Access Driver for example doesn't support this, -1 will be returned).
I am currently working on a simple COM server to make ODBC access easier, and for that reason a function like SQLRowCount, working for SELECT requests, would be very useful, because changing the SQL request by using string operations will make the code much slower, more difficult to code and there may also be much more errors.

Any other solutions?

Don't try it, just do it! Wink | ;-)

As far as i know there is no reliable way to do this across all drivers.

As i understand things (YMMV) :

When you call SQLExecute*() many drivers will return before the complete result set is built - that is they work async. This is not the same as using SQLSetStmtAttr(SQL_ATTR_ASYNC_ENABLE). This is more likely for static forward-only cursors.

The idea is that they can keep chugging away at building the result set as you pull results out of the set via SQLFetch*().

The upshot is that the total number of rows may not be known at the time SQLExecute*() returns.

There are ways to force the issue, but they all introduce significant overhead.

I've built a custom appwizard that creates an ActiveX Component project in the way I want it to, but I'd like to add functionality to it so that it can create projects that are more complex. The wizard presently creates files for a simple class structure, but I'd like it to be able to create a class hierarchy, requesting the number of and the names of the derived classes, and I'd like it use the same template files for creating each derived class (with different value(s) placed into the m_Dictionary variable). Is this possible?

Hi Friends, Wink | ;)

I have some set of problems. Please help me in solving these problems.

if(mPrintDialog.GetDefaults())
{
CDC dc;
dc.Attach(mPrintDialog.m_pd.hDC);
this->PrintClient(&dc, PRF_CLIENT);
}
But this did not worked. Please help me with this problem.
2) I am using MDI application. I tried to handle WM_KEYDOWN of CMainFrame class inorder to capture ESC key.
But it did not worked. Actually when ever ESC is pressed I want to close the application.
3) My another problem is I want to make my application Full Screen. Like I want my view to be of Full screen. When ever user double clicks on the view. I have to make the view a Full Screen. I don't want to see the Background Frame Window. I want my application View to be screen occupyieng whole Monitor screen.

Which means nothing useful. What did not work about it? Was there a compiler/linker error? Did an assertion fire? Was an exception thrown? Did you single-step through the code to see what condition might have cause it to "not work?" What type of object is this?

Child Window in other thread as parent

Kenny Moens21-Sep-04 7:49

Hi,

I'm writing a Flight Simulator DLL, the DLL creates a thread that runs a UI that runs as a child of FS.

Now not any problem in FS window mode, but when I switch to full screen mode and click on the UI (which is shown on top of FS in full screen), windows deactivates the flight simulator by minimizing it and also minimizing the UI.

Without a thread it was working, but I wanted a sep thread for the UI since code behind the UI is doing expensive work.

I create the dialog as follows:

// initialise enumerator class
MyEnumWindowsProcCls Cls;
Cls.dwProcessId = GetCurrentProcessId();
Cls.hWnd = 0;
Cls.dwThreadId = 0;
	
// search for FS Window
EnumWindows(EnumWindowsProc,(LPARAM)&Cls);

fsWnd_ = new CWnd();
fsWnd_->Attach(Cls.hWnd);

dlg->Create(IDD_MAIN, fsWnd_);

The EnumWindowsProc catches the FS window:

BOOL CALLBACK EnumWindowsProc(HWND hWnd,LPARAM lParam)
{
	static MyEnumWindowsProcCls* pCls=(MyEnumWindowsProcCls*) lParam;
	DWORD dwProcessId;
	DWORD dwThreadId;
	dwThreadId=GetWindowThreadProcessId(hWnd,&dwProcessId);
	if (dwProcessId==pCls->dwProcessId)
	{
		char clas[512];
		GetClassName(hWnd,clas,sizeof(clas));
		HWND hWndParent=(HWND)GetWindowLong(hWnd,GWL_HWNDPARENT);
		if (hWndParent==NULL)
			if (strcmp(clas,"FS98MAIN")==0)
			{
				pCls->hWnd = hWnd;
				pCls->dwThreadId = dwThreadId;
				return FALSE;
			}
	}
	return TRUE;
}

Anybody an idea of what I'm doing wrong? Is it possible at all to create a child window in another thread?

Thx
Kenny

Yes, but the secondary thread will need its own message pump. Check out this article for more detail.

Are you only accessing the window from within the thread that creates it? If not you are likely to have problems as Thread Local Storage is used extensively in windows.

Hi all,

I am working on converting some images into BMP format and the given images are in *.LL1 and *.LT1 formats. After converting them into BMP I have to display them in an interface that I am goin to build. (i.e when I select an Image file of any of those two formats fromt he 'open' menu item then it should display the image on a seperate window after doing all the process of changing the format into BMP. ( I am having the header information of the other two formats, but i don't know if it helps)

Anybody having ideas or suggestions of how to convert an image format in VC++, plz lemme know and I appreciate ur help.

I hope I am clear in problem description.

thanks in advance,
Pavan.

I have an options dialog in an app I'm building (an intranet bug reporter/tracker). I would like to be able to put an option in for the user to select whether or not they want the app to run at startup. How can I programmatically create a shortcut and place it in the user's startup folder if they choose this option? Thanks in advance
