Close VC++
go and delete the "NameOfProject.clw" in the Projects directory..
then open VC++
open the project
open ClassWizard it will ask you if you want to rebuild the "NameOfProject.clw"
just do it and it will give you what you want

 Hi all,
I developed an application with MFC using SQL server datatbse.. This appliaction runs fine on my machine having windows 2000 Pro.. I am getting an error while running the same applicaiton on any fresh machine...The error i am getting is
Specified SQL server not found
ConnectionOpen (CreatFile())...as far as i can guess this is the problem because there is no SQL server driver installed on fresh machines..what should i do to make it run any machine...i mean is there any way out so that i dont have to install anything else then to run my applicaiton on client side..and it does all.. any help or pointers are highly appreciated..
thanks a lot in advance..
regards,
Himanshu

You've not shown the actual code that is in error so help is going to be minimal, if at all.
Is the application using ODBC?
|
|
|
|

 hi,
thanks for the reply...yes i am using ODBC in my application...I am trying to install MDAC with the application..now it seems to work fine on other machines where it already doesn't have MDAC..if it has it shows an error again..is there any solution to it???
Please reply???it's very urgent...thanks a lot in advance..
regards
Himanshu

Well, I was going to suggest updating the SQL ODBC drivers but that may not do it. If your program works fine on machines without MDAC installed and produces an error on machines with MDAC installed, I'm at a loss.

hi,
thanks for ur reply...now it doesnt show any error..i am confused however..it was showing the error..but when i built the same setup on my machine(win2000 pro) with installshield..it works fine..and installs the application...and does the work..I am installing MDAC 2.7 ..
thanks a lot anyway..

I have some codes which I don't know how to continue writing. The code goes like this:
HRSRC hrSrc = FindResource(AfxGetResourceHandle(), MAKEINTRESOURCE(IDR_LOCKUP_EXE), "Exe");
HGLOBAL hGlobal = LoadResource(AfxGetResourceHandle(), hrSrc);
LPVOID lpExe = LockResource(hGlobal);
CFile file;
file.Open("C:\Testing.exe", CFile::modeCreate | CFile::modeWrite | CFile::shareDenyNone);
file.Write(lpExe, (UINT)SizeofResource(AfxGetResourceHandle(), hrSrc));
file.Close();
HANDLE hExe = LoadLibrary("C:\Testing.exe");
HRSRC hrSrc2 = FindResource(hExe, MAKEINTRESOURCE(IDR_LOCK_FILE), "LOCKFILE");
HGLOBAL hGlobal2 = LoadResource(hExe, hrSrc2);
LPVOID lpExe2 = LockResource(hGlobal2);
LPBYTE sExe2 = (LPBYTE)lpExe2;
LPTSTR sExe3 = (LPTSTR)sExe2;
CFile file2;
file2.Open("C:\Program Files\Adobe\Acrobat 6.0\Reader\AcroRd32.exe", CFile::typeBinary | CFile::modeRead | CFile::shareDenyNone);
CFile file3;
file3.Open(sExe3, CFile::modeWrite | CFile::shareDenyNone);
file3.Write(???);
file3.Close;
For the ???, what should I put in there so that I can insert the AcroRd32.exe as a binary resource into Testing.exe (I don't want to add in the resource manually)? Or should I rewrite some parts of the code?

|
|
|
|
|
I understand that. But how can I use the UpdateResource function to transform a file into a resource and update the resource of my program?
|
|
|
|
|
Did you look at the "Updating Resources" example on MSDN?
|
|
|
|
|
Yes. But I am not sure how to create a pointer to point to my file that I want to include as a resource and insert into the UpdateResource function. You know how can I do that?
|
|
|
|
|
HANDLE hInputFile = CreateFile("AcroRd32.exe", GENERIC_READ, FILE_SHARE_READ, NULL, OPEN_EXISTING, FILE_ATTRIBUTE_NORMAL, NULL);<br />
DWORD dwFileSize = GetFileSize(hInputFile, NULL), dwBytesRead;<br />
LPBYTE pBuffer = new BYTE[dwFileSize];<br />
ReadFile(hInputFile, pBuffer, dwFileSize, &dwBytesRead, NULL);<br />
CloseHandle(hInputFile);<br />
HANDLE hUpdateResource = BeginUpdateResource("Testing.exe", FALSE);<br />
UpdateResource(hUpdateResource, RT_RCDATA, "Acro", MAKELANGID(LANG_NEUTRAL, SUBLANG_NEUTRAL), pBuffer, dwFileSize);<br />
EndUpdateResource(hUpdateResource, FALSE);<br />
delete [] pBuffer;

Thanks for the help. But when I run the program, it gives me this error when I press the OK button:
Debug Error:
Program:..sktop\LockupApplication\LockupBuilder\Debug\LockupBuilder.exe
Invalid Allocation size: 4294967295 bytes
What's wrong? Please help me.

You cannot allocate that much memory! The absolute maximum that you could allocate is 3GB (and that's only on the advanced flavors of Windows), but that assumes that such a contiguous block exists after everything else is loaded. In reality, the most you could probably get would be little more than 2GB.
|
|
|
|
|
ok. so is there any way to solve this problem ('cause i got this error when I added the code that you have given me into my program)?

What about the suggestion(s) in this thread?

Thanks for the reference. I have seen the thread. But, how can I allocate an amount of memory first so that I will not get the allocation problem when I run the program?
My code is now like this:
HRSRC hrSrc = FindResource(AfxGetResourceHandle(), MAKEINTRESOURCE(IDR_LOCKUP_EXE), "Exe");
HGLOBAL hGlobal = LoadResource(AfxGetResourceHandle(), hrSrc);
LPVOID lpExe = LockResource(hGlobal);
CFile file;
file.Open("C:\Testing.EXE", CFile::modeCreate | CFile::modeWrite | CFile::shareDenyNone);
file.Write(lpExe, (UINT)SizeofResource(AfxGetResourceHandle(), hrSrc));
file.Close();
HANDLE hInputFile = CreateFile("C:\Documents and Settings\Administrator\My Documents\Testing.txt", GENERIC_READ, FILE_SHARE_READ, NULL, OPEN_EXISTING, FILE_ATTRIBUTE_NORMAL, NULL);
DWORD dwFileSize = GetFileSize(hInputFile, NULL), dwBytesRead;
LPBYTE pBuffer = new BYTE[dwFileSize];
ReadFile(hInputFile, pBuffer, dwFileSize, dwBytesRead, NULL);
CloseHandle(hInputFile);
HANDLE hUpdateResource = BeginUpdateResource("C:\Testing.exe", FALSE);
UpdateResource(hUpdateResource, "LOCKFILE", "IDR_LOCK_FILE", MAKELANGID(LANG_NEUTRAL, SUBLANG_NEUTRAL), pBuffer, dwFileSize);
EndUpdateResource(hUpdateResource, FALSE);
delete [] pBuffer;

Hello All
I have a small DialogApp(mfc). when I compiled it with vc7, the exe runs fine on NT4, Win2k and XP, but when trying to run it on Win98, Win98 kept saying that the exe image is corrupted. I wonder if anyone've seen the problem and know why?
PS. mfc and CRT is statically linked into the exe.

|

normally its the other way round.. but 98 suxx indeed
Don't try it, just do it!

Are u compiling your program in Unicode ? if u are, then it will not run in legacy windows (WinME, Win98, Win95).

Hey,
My prog is supposed to communicate with an external device with the serial port.I ve got some trouble trying to get it working...
If I don t run the hyperterminal before using my software, the communication doesn t work.I ve tried to use overlapped and nonoverlapped communication.I ve tried to use a couple of activex controls and different classes.But it's still the same.Moreover, I am almost sure that my initializiation parameters are OK.
Has somebody already had this kind of bug?
What does the hyperterminal do that my prog doesn t?
I tried to use a sniffer to find out what s going on in my communication, but everything looks find as well.
If you have any ideas, please feel free to share ur thought....
I ve been trying to debug my softare for 2 weeks now...
Thanks for ur precious help.

You can use PortMon[^] to compare the settings of the terminal program with those of your application.

Cable
If hyperteminal works then it should be OK
Data
You are using a sniffer, have you tried using 2 PCs with your prog on #1 and hypertermial on #2? Or use 1 PC with two serial ports?
CreateFile
CreateFile can be used to send serial data, search MSDN for "Configuring a Communications Resource" try this and send a test string to another PC that has hypertermial running, e.g. send "hello world". This should prove out your line settings baud rate, stop bits, parity etc. I assume this is where you problem is.
With serial comms I always found is easiest to buy a comms library, the last one I used was COMM-DRV.
Generally the problems are caused by the cable, handshaking, or not setting the DCB block in SetCommState
A favourite problem is using XON/XOFF protocol and sending XOFF, also some devices/computers will conver a LF to CR/LF unless line characteristics are set to raw mode.
So do a simple test to prove it works sending to hypertermial, that will elinate the receiving prog/device.
It is amazing what you can accomplish if you do not care who gets the credit. - Harry S Truman
