Re: Grids Tomasz Sowinski3-Oct-01 4:37 Tomasz Sowinski 3-Oct-01 4:37  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. Tomasz Sowinski -- http://www.shooltz.com Re: Grids 3-Oct-01 4:41 3-Oct-01 4:41  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 Re: Grids NormDroid3-Oct-01 4:46 NormDroid 3-Oct-01 4:46  search for Grid on the home page, Chris Maunder (site administrator) has written a grid for VC. Norm Almond Chief Technical Architect FS Walker Hughes Limited warning C4786: zack3-Oct-01 3:10 zack 3-Oct-01 3:10  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 Re: warning C4786: Tomasz Sowinski3-Oct-01 4:40 Tomasz Sowinski 3-Oct-01 4:40  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 Tomasz Sowinski -- http://www.shooltz.com Re: warning C4786: zack3-Oct-01 4:57 zack 3-Oct-01 4:57  Now I rebuilded the app putting the #pragma warning(disable : 4786) before everything, and it seems to work. thanks you Tomasz Re: warning C4786: John M.

Accessing Data Islands from a COM component on a HTML page Michael A Barnhart3-Oct-01 3:08 Michael A Barnhart 3-Oct-01 3:08  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. <title>Untitled Hello All <xml id="MyData"> <mydata> <object id="Viewer Control" ="" classid="CLSID:6E7B198C-106F-11D4-BAA0" width="820 " height="550 "> <param name="DataSource" datasrc="#MyData" /> <param name="WebName" value="Item" /> <param name="WebAddress" value="Address" /> <param name="WebPort" value="80" /> End Hello Michael A Barnhart mabtech@swbell.net RAS Dial Firoz3-Oct-01 2:38 Firoz 3-Oct-01 2:38  I have one problem regarding RAS...

Thanks. Re: CEdit 3-Oct-01 1:41 3-Oct-01 1:41  try \r\n Re: CEdit 3-Oct-01 1:58 3-Oct-01 1:58  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. Re: CEdit Chris Losinger3-Oct-01 2:02 Chris Losinger 3-Oct-01 2:02  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 ------------------------------ Smaller Animals Software, Inc. http://www.smalleranimals.com Re: CEdit 3-Oct-01 2:46 3-Oct-01 2:46  Thanks for help,it works. Get list of all COM-Objects 3-Oct-01 1:32 3-Oct-01 1:32  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 Re: Get list of all COM-Objects Michael P Butler3-Oct-01 1:53 Michael P Butler 3-Oct-01 1:53  Use OleView that comes with the Platform SDK / Visual Studio. Michael Re: Get list of all COM-Objects 3-Oct-01 2:27 3-Oct-01 2:27  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 Re: Get list of all COM-Objects Michael P Butler3-Oct-01 2:57 Michael P Butler 3-Oct-01 2:57  You can view IActiveDesktop methods here http://msdn.microsoft.com/library/default.asp?url=/library/en-us/shellcc/platform/shell/IFaces/IActiveDesktop/IActiveDesktop.asp Michael Why did I get a error message on the call to CFtpConnection's SetCurrentDirectory()? Chaos Lawful3-Oct-01 1:17 Chaos Lawful 3-Oct-01 1:17  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.

CDialog in a dll 3-Oct-01 1:14 3-Oct-01 1:14  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? VC++ 6.0 Fail... 3-Oct-01 1:12 3-Oct-01 1:12  I have a strange problem.
