Dear:
yes, because I did before in same function this bulk of code :
[Code]
//Get the header informaion
BOOL bStatus = pfc->GetServerVariable("ALL_HTTP",Buffer,&BuffSize);
CStdioFile file("C:\\log.txt",CFile::modeWrite | CFile::modeRead);
file.WriteString(Buffer);
file.WriteString("\n--------------------\n");
SetFilePointer(file.m_hFile,0,0,FILE_END);
file.Close();
then i see the Header contents in log.txt without any problems.
but when add the code the relates to Database IIS Crashed!!!!
I dont know why?
The page i have done in .NET (user.aspx) has 3 images 2 buttons and two textboxes ,so for each one the page will do request to IIS ,does that cause the problem? because on each request i open,retrieve information ,and close the database connection.
Thanks

Dear:
Moreover i tried to debug the ISAPI DLL , the unhandled exception occured at this statement
dbConnection.Open("ODBC;DSN=MyDSN;UID=sa;PWD=;database=Users");
the Message Flaged after excuting above statement
**************************************************
Unhandled exception at 0x7c57e592 in inetinfo.exe: Microsoft C++ exception: CDBException @ 0x00dae950.
Why this happened?
Thanks

Is MyDSN a user DSN or a system DSN? I suspect that CDatabase::Open is throwing an exception. Should should be catching that, and seeing what the error is.

|

Dear :
MyDSN is found in User DSN and File DSN, and after debugging the exception raised is:
Unhandled exception at 0x7c57e592 in inetinfo.exe: Microsoft C++ exception:
CDBException @ 0x00dae950.
this occured after Open() is executed for database connection.

I am design a program's interface,now I want to make the background of CListCtrl transparent,but I dont know how to implement it,please help me!

On Win2K and above you can use SetLayeredWindowAttributes()
This link might help

NOTE: You can apply this to any window. Including the CListCtrl.

i want to write a windows service.
i tried to tried one. there is 2 .cpp file and 1 .h file. the exe is created but there is runtime error. actually i opened a WIN32 Application project and then added the files to the project and then created the executable.
what is the correct way to create a windows service app.
please send some links?

Hi,
Why dont you use the App Wizard to create a new ATL COM AppWizard and from the list select Service(EXE). The AppWizard handles all the interface with the Service Control Manager. All that you need to do is add code in the Run() function.
Hope this helps you.

HI,
Wt is the difference between Static link library and Dynamic link library.
and how can we create them.
thanx
Regards.
|
|
|
|

Hi,
Static libraries are included at compile time, and dynamic libraries are loaded at run time. Dynamic libraries are the .dll files you see around windows directories.
To create the libraries in VC6 use the AppWizard. Static libraries are the easiest to use, just create a dependancy on the workspace that needs to use the library. The workspace will take care of including the library code, etc.
Dynamic libraries are a bit harder to use, but once you have used them for a while they become easier. You can either create MFC dll's or Win32 dll's. Creating them through the AppWizard will give some eg code on how to use them.
I hope this helps 
cheers,
Rich

# 1
Static libraries are linked at compile time. Dynamic
libraries are linked at runtime
# 2
static library is faster than dynamic library
# 3
above answer is correct and..
the excutable exe size will be larger when we build exe
with static library compared to dynamic library
# 4
Above answers are correct. In case of Dynamic Library your
executable will look up for the code at run time. E.g. when
running some exe it looks for help from some .dll files
provided by windows operating system. So we call this
dynamic linking.
# 5
The static linked library causes the corresponding information from libraries to be included in the executable DLL on the other hand inserts virtual address of memory. Thus the size of static linked file is larger than a static linked file. If we use dynamic linking the updates in library will also be effect the behavior of the file while not in static linking. Due to this reason dll is better but it can also sometimes make the program faulty due to library update.

Suppose i have a string like
CString csPath = "c:\\windows\\test.exe -parm1"
or
CString csPath = "c:\\windows\\test.exe /parm1"
now to test whether test.exe exists or not
i can't just use csPath and call GetFileAttributes that will fail because of the commandline arguments
i will have to extract the application path from the full command line which will be tedious(the examples above are easy but there are more complex ones like:
C:\WINDOWS\ISUNINST.EXE -f"C:\Program Files\Adobe\Photoshop 5.5\Uninst.isu" -c"C:\Program Files\Adobe\Photoshop 5.5\Uninst.dll")
any help suggestions are welcome

Why not use:
TCHAR szDrive[_MAX_DRIVE];
TCHAR szDir[_MAX_DIR];
TCHAR szFname[_MAX_FNAME];
TCHAR szExt[_MAX_EXT];
::_tsplitpath(csPath, szDrive, szDir, szFname, szExt);
Then, just check to see if you have the filename and extension in szFname and szExt.

if i want to access value of the textboxes in previous dialog (for both modal and modeless) into the new dialog
veda

use SendMessage with ur parameters as wparam/lparam.

thanks first,,
what mean CFileException::accessDenied (m_cause is 5 ) ?
msdn just says "The file could not be accessed."
|
|
|
|
|
That's what it means. It means the file is not there, or you can't do what you were trying to do to it ( for example, open a file for writing if it's on a CD, or is read only )

Is it possible to inspect or print out either the typeid of a pointer to a c++ class, or the actual value typecast e.g. if I have 'class parent {}' and 'class child : public parent {}', and in the routine I want to debug I have a 'parent*' that I'm pretty sure is actually of type 'child', is there a way I can bring that up? I've tried the command window, in both command mode and immediate mode, but I can't figure out the right syntax to use.

Looks like the RTTI to me.
To print out, check codes below (from MSDN)
Makesure, you have your project RTTI enabled.
// expre_typeid_Operator.cpp
// compile with: /GR /EHsc
#include <iostream>
#include <typeinfo.h>
class Base {
public:
virtual void vvfunc() {}
};
class Derived : public Base {};
using namespace std;
int main()
{
Derived* pd = new Derived;
Base* pb = pd;
cout << typeid( pb ).name() << endl; //prints "class Base *"
cout << typeid( *pb ).name() << endl; //prints "class Derived"
cout << typeid( pd ).name() << endl; //prints "class Derived *"
cout << typeid( *pd ).name() << endl; //prints "class Derived"
delete pd;
}

In my multithreaded dialog-based app, I'm popping up two modal dialogs at the same time (in seperate ON_FOO_MSG handlers). When one closes, I'd like focus to return to the other, but right now it returns to the main dialog instead. Calling SetActiveWindow() or SetFocus() or SetForegroundWindow() on the remaining dialog brings it to the foreground, but the dialog still won't accept any keyboard input (somehow, ESC still closes it, though).

This is not a good design. Only one thread should be controlling the user interface.
In MFC, only one window can be inside a modal loop at any time. As soon as the dialog closes, modality returns to the dialog that was previously modal. There's nothing you can do about it without closing your main dialog. If you want to go from one to the other, you'll have to show the first one (and not the second one), and then show the second one when the first one closes.
