Hi,
I work with Visual C++6.0 SP5 under Windows 2000 SP2
I have theis following problem to compile my project in visual c++6.0
I want to connect to a data source (sqlserver or db2). If i attemp to compile my project, the following error message is display :
------------------------------------------------------------------------------
f:\progra~1\sqllib\include\sqlext.h(1676) : error C2146: syntax error : missing ';' before identifier 'SQL_API'
f:\progra~1\sqllib\include\sqlext.h(1676) : error C2501: 'SQLRETURN' : missing storage-class or type specifiers
f:\progra~1\sqllib\include\sqlext.h(1676) : fatal error C1004: unexpected end of file found

Can anybody help me ?
Thanks in advance

It probably is part of your project, you just can't see it. Check your include files it is being added by some other file. You may need to change the order of your includes.

You should make sure Sql.h and Sqltypes.h are included whereever you are trying to use ODBC

In my application I'm accessing to several database servers through ODBC (oracle, sql-server, sybase, ...) and I need to access to some system tables, that's the reason what I need to know in which of those systems I'm connected.
I can try to access to a specific table with a "try ... catch" but it's not a "pretty" solution.
Any idea?
Thanks.

Is can I to return a parameter in the program termination in exe file ?
|
|
|
|
|
look in help for main, wmain etc. - they return int
t!
|
|
|
|
|
Can you explain your answer ???
|
|
|
|
|
your program can look like this:
int main(void)
{
return 7;
}
calling .bat can work with it:
program.exe
if errorlevel 7 goto END
also you can do this:
void main(void)
{
exit(7);
}
it is better now?
t!

I have recently moved away from MFC, and focussed on Win32 programming instead. But I am having problems with safe drawing of DCs, particularly the SelectObject() and DeleteObject() functions. I know that whenever you create an object and select it, you must get the old object so you can put it back when your finished. I found some source code for this and it went something like this:
HBRUSH hbrNew = CreateSolidBrush(RGB(255, 0, 0));
HBRUSH hbrOld = SelectObject(HDC, hbrNew);
// Drawing Stuff...
SelectObject(HDC, hbrOld);
DeleteObject(hbrNew);
But this doesn't work with the compiler. It has a problem with the hbrOld being a HBRUSH. If anyone can help or tell me how to do it properly, it would be greatly appreciated.

SelectObject returns HGDIOBJ - you have to cast the return value to HBRUSH --or-- declare hbrOld as HGDIOBJ.

Correct. Either way you will have to use a cast:
method 1:
HBRUSH hMyBrush = CreateSolidBrush(RGB(255,255,255));
HBRUSH hBrushOld = (HBRUSH) SelectObject(myDC,hMyBrush);
//Draw Here
SelectObject(myDC,hBrushOld);
DeleteObject(hMyBrush);
method 2:
HBRUSH hMyBrush = CreateSolidBrush(RGB(255,255,255));
HGDIOBJ hBrushOld = SelectObject(myDC,hMyBrush);
//Draw Here
SelectObject(myDC,(HBRUSH)hBrushOld);
DeleteObject(hMyBrush);

Not true. Version 2 doesn't need a cast to HBRUSH
HBRUSH hMyBrush = CreateSolidBrush(RGB(255,255,255));
HGDIOBJ hBrushOld = SelectObject(myDC, hMyBrush);
SelectObject(myDC, hBrushOld);
DeleteObject(hMyBrush);

Hi all,
I want to use of use of two table in only one CDaoRecordset object ...

You can use a join as: "SELECT * from table_one,table_two where table_one.column=table_two.column"
Therefore Overload the GetDefaultSQL() function of CDaoRecordset and return "table_one,table_two"

Hi,
I'm having a rather weird problem here and I thought that maybe, if I described it, it would ring some bells with the experts. I haven't a clue!
Anyway, here's the situation:
We have an in-house developed database-access layer with all kinds of specific goodies in it and for reasons of deployment and ease of upgrade, we isolated it in an MFC extention DLL.
This all worked fine for a couple of months. I can integrate it easily in existing programs and everything works fine... that is, as long as I integrate it in an exe!
The database-access layer in the DLL has a feature which displays a tray-icon. You can see what the layer is doing by looking at the tray-icon's color or by calling a dialog, hidden in the tray-icon's context menu. Of course the dialog and tray-icons are all located in the resource of the extention dll...
As long as I integrate the extention dll in a stand-alone application (.exe), everything works fine, tray-icon included. But when I integrate the dll in an activeX-component (complete with clsid and interface) the tray-icon's icon cannot be loaded from the resource! In release build this results in a tray-icon without an icon (just an empty space) which isn't THAT bad, but when I try to bring up the dialog it fails completely (which you might expect). In debug build I get all sorts of assert-failures saying that the icon HANDLE is invalid...
So how come everything works fine in a stand-alone application and it fails in an ActiveX component?

use AFX_MANAGE_STATE(AfxGetStaticModuleState()) in your DLL.
see MFC technical note 058 for more info
if it doesn't help, you can set the resource handle manually in the DLL
HINSTANCE hResPrev=AfxGetResourceHandle ();
AfxSetResourceHandle (GetModuleHandle (_T("CT.DLL")));
...
AfxSetResourceHandle (hResPrev);

MFC Extension DLL will work correctly only if your exe is also MFC app linking dynamically to MFC. With ActiveX, your .exe is a container - you can't expect all apps hosting your ActiveX to be MFC apps.

I'm trying to write a dll that when fed a process ID, displays the UDP ports the process is using/resources process is consuming.
How can I do this? any articles/code, links would be useful.
TIA.

Hi all,
I've got one question here about the installshield.
How do I know what dll should I insert into my installshield program??
Now I try to create one installshield for my application. I copied all the
dlls needed but I'm not really sure whether they are correct or not. When I
try to install the application it works fine but it automatically dispose
the dialog box. This is happen when I install in a new pc ( with no visual c++). However, when I
tested on my pc ( which got visual c++), the application works fine. My
application is a dialog based application which using thread.
Thanks in advance. 
Regards,
Farah

If you are asking what files you need to run your program then you can use the program Depends which comes with VC++. It will show you which files your program requries.
If you're asking what files you need to run install shield then read the documentation. There's a section on distributing your install program.
When you say "automatically dispose the dialog box" do you mean it closes automatically right after you start it? If that's the case then there could be lots of reasons it's failing. I suggest running a debug version of your app on your other system.

Say I have DialogX with its code compiled into xstuff.dll. How would I open this dialog from an application such as getx.dll.
Thanks

Opps. I forgot to say I am working with MFC in both.

You would need to export a function in the dll to display the dialog, then use it.
One method (not actual code):
LoadLibrary(getx.dll)
GetProcAddress(DispalyDialog)
Call method to display dialog
