I'm making a small utility app that uses ReadDirectoryChangesW(). Everything works fine while the directory I'm watching is on my local machine. But when I try to monitor a network folder, I get the error "An unexpected network error occurred." everytime a file is added (or any other type of file operation in that folder). Does anyone know what's going on? I have complete rights to the folder, so I would guess my app does too, but I may be wrong about that.

Check GetLastError() after ReadDirectoryChangesW(). That should tell you what's wrong.
I'm not sure that you can use ReadDirectoryChanges on drives other than a local drive. Check the docs. I certainly can't see it working on non-Windows drives.

GetLastError() returns "An unexpected network error occurred.". I've gotten it to work on network drives, but I suspect that it's because the folder is not actually a windows directory that something is crashing. It's actually a Unix machine mapped into our network to look like a regular windows folder.

I would be surprised if it worked on Unix drives so this makes sense.

It works fine when I compile under VC 6.0 but when I convert the project to a VC .NET "solution", the following line will return a NULL pointer:
Code:
CWnd* pWnd = GetParent()->GetDlgItem(edt1);
Any helps?

Please advise MFC libraries for drawing diagrams/charts. As tried I couldn't find anything suitable for me.

There are none, just the wrappers on the core GDI stuff that lets you draw lines, etc. There is no fully fledged chart drawing code in MFC. You have to write it.

I really like the Smart Tag control in Office XP. Have anyone an idea how to make such a control in your own program?

hello,
The program that I am making needs to allow the user to upload a file from his harddisk by pushing a button just like he would normally do on a php page.
The file must be uploaded via php on remote server of course.
I am trying a trick I saw on a website since php no longer supports just plain uploading without the user pressing some kind of button I have beet trying to simulate a button pushing like this:
<br />
<br />
strcpy(lpContentLength, "Content-Length: %d\r\n"); <br />
strcpy(lpContentType, "Content-Type: multipart/form-data; ");<br />
strcpy(lpPOST, "POST");<br />
strcpy(lpMimeHeader,<br />
"-----------------------------7d414e351603fa\r\n"<br />
"Content-Disposition: form-data; name=\"upload\"; filename=\"%s\"\r\n"<br />
"Content-Type: application/octet-stream\r\n"<br />
"\r\n"); <br />
strcpy(lpMimeTail,<br />
"\r\n-----------------------------7d414e351603fa\r\n"<br />
"Content-Disposition: form-data; name=\"submit\"\r\n\r\n"<br />
"Upload Files\r\n"<br />
"-----------------------------7d414e351603fa--\r\n");<br />
strcpy(lpUserAgent, "Mozilla/4.0 (compatible; MSIE 6.0; Win32)"); <br />
<br />
sprintf(szMimeHeader, lpMimeHeader, lpFilename); <br />
sprintf(szMimeTail, lpMimeTail);<br />
MessageBox(0, szMimeHeader, "ada", MB_OK);<br />
MessageBox(0, szMimeTail, "ada", MB_OK);<br />
dwMimeHeaderLen = strlen(szMimeHeader);<br />
dwMimeTailLen = strlen(szMimeTail);<br />
then of course I read the file, stick the MIME at the end of it and use win32 internet functions to get the data to the php waiting on the other side but it doesn't work, anyone know why? Is the mime header wrong?
I could provide the rest of the code also if you think there might be something wrong with it.

Hello Everybody
I am using VC++ and trying to insert records into an Excel 2003 sheet using ODBC.
The table has been created and the ranges named but it is only inserting one record and then I am getting rhe "cannot expand named range" error.
Now when I change the range definition I am getting a "spreadsheet is full" error.
I am not sure what is going wrong and any help would be greatly appreciated.
Here is my code for inserting:
CDatabase db1;<br />
if(!db1.IsOpen())<br />
db1.Open(NULL,FALSE,FALSE,_T("ODBC;Driver={Microsoft Excel Driver (*.xls)};DSN='';DBQ=TT_Database.XLS;ReadOnly=False"),TRUE);<br />
<br />
strSQL1 = "INSERT INTO tbl_AllCaptured(TickerSymbol,FIELD_PRICE, FIELD_VOLUME, DateOfCapture) VALUES('GE',25.57,45,#10/10/2000#)";<br />
<br />
db1.ExecuteSQL(strSQL1);<br />
db1.Close();
Thanks & Regards

Hi,
Everybody. Do any one know how to write flash programming in VC++. Means how to parse SWF files and and how to run it ... etc...
Thanks in advance.

There's a flash SDK for creating swf's. If you want to view them, I'd say you want to embedd IE in your app.

Yep, but embedding the Flash OCX control is a lot easier

Maybe the macromedia Flash SWF SDK can help

I'm attempting to write a managed wrapper interface to a native C++ class such that I can access it from within my C# code.
I'm using Visual Studio .NET 2003 on Windows 2000.
I started a new solution: Visual C++ Projects > Class Library (.NET)
My Stdafx.h file has the following in it:
#pragma once
#define WIN32_LEAN_AND_MEAN
#include <windows.h>
#include <iostream>
using std::cout; using std::endl;
In the Solution Explorer, under Source Files I have the following:
1. AssemblyInfo.cpp
2. BiquadCode.cpp (native C++ code)
3. DSPWrap.cpp (the wrapper code)
4. Stdafx.cpp
Under Header Files, I have:
1. BiquadCode.h
2. DSPWrap.h
3. resource.h
4. Stdafx.h
I've "included" the Stdafx.h file in the first statement of DSPWrap.cpp.
On a build attempt, the code generated a C1010 error. For the files BiquadCode.cpp and BiquadCode.h, I've now set the precompiled header option as "Not using precompiled headers".
However, this throws a C1034 error
<path>\DSPWrap\DSPWrap\Stdafx.h(9): fatal error C1034: windows.h: no include path set
My questions are as follows:
1. How do I get this code to compile?
2. Where exactly do I need to "include" the Stdafx.h file? Do I need to do it only once in the wrapper code file?
Thanks in advance!

Hi,
In my application, I draw in a dialog with OnPaint() member function.
It is functionning well when the dialog is created and displayed.
In the dialog, I can change the dimension of the drawing. But I am not able to update the drawing unless I quit hte dialog and I come back.
How can I update my dialog on the fly ?
Thanks,
Claude

|
|
what do you mean "change the dimension of the drawing" ? by resizing the dialog ? or by setting the size manually with some numerical values ?
are your sure you're not computing some sizes in the OnInitDialog and never in the OnPaint ?
You could Invalidate the dialog....

I wrote a COM Server using ATL wizard, so i made a DLL, and want to use it on another machine - but, when i try to register my server using regsvr32 i have next message:
"LoadLibrary("the way to my dll") failed. The specified module could not be found".
Where the problem is???
|

|
|

is it a COM DLL ? or ordinary one ?

Does the path/file specified in the call to LoadLibrary() exist? Are you using an absolute or relative path name?

Assuming you have specified the path to your DLL correctly then your module is probably dependent on another module that is not present on the second machine. Check you are using a release version, or have installed the relevant debug libraries to the second machine. Try using the depends utility to see what modules your DLL is dependent on.
