I am looking for a "unmanaged" implementation of the .NET DataSet and its
associated objects that is written in Visual C++ (with source if possible).
I need an implementation that does not rely on the .NET FrameWork, yet is
compatible with the .NET DataSet's so I can share the XML form of the
DataSet between unmanaged clients (.NET is not installed on the clients) and
a .NET web service. We will be using the DataSet's as our universal
datapacket to pass data between the client and server.
I am trying to put off having to implement a solution myself in ATL so I am
doing some research first.
Thanks in advanced for any information or assistance.

Hi,
I'm tying to implement a FORTRAN application (that i've gradually written over the last 12 or so years) in windows. I'm getting the hang of VC, but need some advice...
My plan is to implement all the "work" of the application (a lot of complex maths) in fortran, in a Fortran Powerstation 32 compiled DLL, and then use VC to create the WIndows UI of my application.
The input for the application is a matrix of numbers. The obvious, ideal UI implementation of a way of getting this input data is to implement something with a Microsoft Excel style grid. It would need 5 columns, and n rows (ie. user would be able to insert new rows).
Anyway, I've been hunting down methods of doing this by trawling through MSDN. The only way I've found is to use the MSFlexGrid Object. But this doesn't really appeal: it seems to be a bit of an over-the-top approach, and it's programming interface is a bit awkward.
So, my question is: Is there a better way to implement a simple, excel style grid? and where can I find out about it.
Thanks in advance for your help

There's a MFC-based grid right here at CodeProject; go to Controls/Misc section. I think it has all the features you need.
And if you want to spare some money, there are at least two commercial packages: Objective Grid from Stingray and Ultimate Grid from Dundas.

I feel a right fool now... I just found that grid myself!
Thanks for your help anyway!
I eyed up that DUndas software one, but I can't really afford it since this is just a pet project and not associated with work at all.
And the software won't be commercial anyway: how many people would want an application which plots grapic natural harmonics of turbines? not very many.
Thanks again
Richard

search for Grid on the home page, Chris Maunder (site administrator) has written a grid for VC.

Does anyone know how to prevent the really annoying compiler
warning C4768 ('identifier' : identifier was truncated to 'number' characters in the debug information)? (normal when working with STL)
I want to use warning level 4 and the
#pragma warning(disable: 4768) doesn't work, or not everytime.
thanks
 zack

The #pragma works, at least for me. You just have to put it before #including STL headers. Usually, I place it at the top of stdafx.h

Now I rebuilded the app putting the
#pragma warning(disable : 4786)
before everything, and it seems to work.
thanks you Tomasz

I have a number of COM components (all written with VC++) that are used on an internal web page. I have been accessing the data to use by defining a http url in the PARAM tags within the OBJECT tag that loads the component, which then makes its own request. I would like the option of just including the associated data (it is all XML) via data islands (the XML tag) and then letting the embedded component access its data from there.
However I have not found the link, call, whatever to access this data from the comonent. getting the PARAM data was straight forward but I just am not searching for the right key words etc to go on.
Any pointers to the correct steps to take are appreciated. Just key words to the MSDN lib search would be helpful or of course a code snippet would not be refused.
Below is a sample of the html page: I have tried various options for the data source definition but all tries have only returned a NULL string (or pointer) to my control.

It is working fine on a win98 system.
But its not working on winNT server.
Please help me... 
Here is the code, I used...
////////////////////////////////////////////////////////////////
RASDIALPARAMS RASParams;
RASParams.dwSize = sizeof(RASDIALPARAMS);
sprintf(RASParams.szEntryName,"%s","My ISP");
sprintf(RASParams.szPhoneNumber,"%s","");
sprintf(RASParams.szCallbackNumber,"%s","");
sprintf(RASParams.szUserName,"%s","");
sprintf(RASParams.szPassword,"%s","");
sprintf(RASParams.szDomain,"%s","");
HRASCONN m_hRas = NULL;
// For connecting
if(RasDial(NULL,"C:\\WinNt\\System32\\ras\\RasPhone.pbk",&RASParams,NULL,NULL,&m_hRas) != 0)
{
::MessageBox(NULL,"Error: RasDial","",MB_OK);
}
// For Disconnecting
if(m_hRas)
{
RasHangUp(m_hRas);
Sleep(3000);
}

Hello,
How to create a new line in Edit control?
Thanks.
|

It doesn't work.
In my example i try this
For(int i = 0; i < 10;i++)
{
m_edMyEdit.SetWindowText((LPCTSTR) "text");
}
VC++ write "text" in place of the old text.
Even if i write "text\n" or "text\r" the problem persists.

SetWindowText sets the entire text of the window.
if you want to add text, you have to use SetSel and ReplaceSel:
m_edit.SetWindowText("text\r\n");
CString t; m_editGetWindowText(t);
m_edit.SetSel(t.GetLength(), t.GetLength());
m_editReplaceSel("Text\r\n", false);
-c

Hi
how can I get a full list of all interfaces like "IActiveDesktop", "IPersistFile" and their methods?
Of course I could browse the shlobj.h file, but thats a lot of work and not understandable at a glance
|
|
|
|
|
Use OleView that comes with the Platform SDK / Visual Studio.

thanks
But I can't view the methods of interfaces like "IActiveDesktop", the button "View Type Info" is disabled But IActiveDesktop definately has some methods like getwallpaper

I'm writing a multi-threaded FTP searching program under Win 2k. But sometimes I got error message like "memory 'XXXXXXXXX' cannot be 'written'" from WININET.DLL and sometimes I got "Unhandled exception" from NTDLL.DLL when I call SetCurrentDirectory() to get into the child directory. The child directory actually exists, and MSDN said these functions don't throw exceptions! I was completely confused. What cause this error? Could anyone give me some suggestions? Thanks a lot.

With eVC++ Version 3.0 for PocketPC I've tried to export a CDialog-based class and then use it in an application. DoModal() always fails. I have stepped through the DoModal() method and it fails because it cannot find the resource. The only way I have been able to get this to work is to use a wrapper function in the dll then call the wraper function from my application. I've tried several things, such as changing the dialog ID to make sure it is unique. Anyone know of a solution to this problem?

I have a strange problem.
I use Visual C++ 6.0 and it woks well,
but today, I install the Microsoft Global IME (Japanese) for reading Japanese on my IE5 and Outlook, then My Visual C++ has problem after i use Debug functions (step into, go...).
The problem is when i enter debug mode to debug my source and stop to make modify my source. The second time i want to enter the debug mode, the VC failed and show a dialog box says MSDev is going to close.
I remove the Global IME but this problem still happend...

Reinstall the last service pack for Visual Studio, maybe that will do.
