• Visual Basic DLL sending message to vb aplication

  From my VC++ DLL how can i send a message to my vb application please help me!!!!!!!!!!!!! You will need to be more specific for someone to be able to help you. In the meantime, you can create an ActiveX control in VC++ that sends the event. On the VB .Net side you can add the control to your form (withevents) and add the appropriate handler.

• Visual FoxPro MySQL and VFP

  Hi experts. I have a MySQL database. I operate with them using syntax like SQL(sqlhandle, "select * from...") I copy them into cursor and than operate with a cursor. Is there a simplier way how to work with them Thanks in an advice. >> I understand but I have asked whether the problem may be that I am using free MySQL database, whether this speed isue can be one of the database limits. And the answer, as I have told you at least twice, is that My SQL is used by thousands of people all over the world and speed does NOT seem to be an issue for any of them. I am sorry but I do not NOT use MySQL (I have enough problems dealing with SQL Server 2000, SQL Server 2005 and Oracle i ...Show All

• Visual Studio 2008 (Pre-release) sending 30 MB from a WCF server to many clients

  I need to create a solution for this scenario: A lot of clients all over the world (winforms) should play media files that a server sends them. The server has a playlist of media files for each of those client. Whenever a playlist is changed on the server the client should 'know' about it and download the media files. the size of the files could be around 30 MB. Should I use WCF to send the files to the client or should I use FTP instead What is the diference between WCF and FTP in terms of speed , security and scalability >>What is the diference between WCF and FTP in terms of speed , security and scalability Speed - FTP probably is going to give you better perfomance.

• Windows Forms ClickOnce Fails with "Value does not fall within the expected range."

  I have a ClickOnce-deployed application installed in offline mode across a range of Windows 2000/XP machines on my network. I now receive an 'Application cannot be started. Contact the application vendor.' error message when I attempt to run the application on my development machine. (It works still on the production machines.) I've run mage -cc, and renamed the '2.0' directory to '2.0x' to ignore its presence. Add/Remove Programs still shows it, and clicking Change/Remove pops up a window for a moment, but otherwise does nothing apparent. I've changed the installation path to be a network path instead of a website, and it still fails. The following is the error log: PLATFORM VERSION INFO Windows : 5.1.2600.131072 (Win32NT) Comm ...Show All

• SQL Server How to orginize MDX Scripting development? Best practices are wanted!

  Hi MDX Gurus, Could you please give me a properly advice. I make a lot of MDX scripting development. Today I made script changes in BI Studio, then deploy cube (changes) to the server, then test it with MDX queries from Sql Management studio. Both tools take some hundreds MB RAM and aren't quite fleetly. Do anybody have some hints to better shape this process Darren Gosbell wrote some great code for being able to deploy the calc script from Visual Studio: http://www.codeplex.com/bidshelper/Wiki/View.aspx title=Deploy%20MDX%20Script&referringTitle=Home It's VERY fast and VERY lightweight. No cube processing involved. It uses the Alter statement under the covers. ...Show All

• Windows Live Developer Forums MSN Messenger is still the best!

  The saddest part of upgrades is the process of working glitches out of the software. I have learned how to hide the "shared folder" from being seen in "My Computer", but the "shared folder" in "My Documents" is another mystery yet to be explained. Great the people want to share their files, but for those of us who don't want a "shared folder" and like to transfer our files by zipping them first and using MSN Messenger, I still find that MSN Messenger 7.5 is superior. It also loads faster, it has enough bells and whistles to please most of us, and the video/voice chat works great! If someone can tell me the real way to disable all appearances of "shared folders", perhaps I ...Show All

• Windows Live Developer Forums Windows Live Search API (Needs to be Simplified)

  I was pretty disappointed with the amount of code it takes to return search results from the Windows Live MSN Search API. Why should I have to maintain three separate class and 60+ lines of code to return a simple list of related search items. My recommendation would be something like. '--------Return a simple list of results-------------------- Dim objMSNSearch as New com.msnSearch.www Dim strXML as string objMSNSearch.Results = 3 objMSNSearch.KeywordSearchText = txtKeyword.text objMSNSearch.AppID = "ABCDEFG" objMSNSearch.DisplayCache = True strXML = objMSNSearch.WriteSearchResultsXML 'This would return...... <MSN> <SearchResult> <SearchTitle>Star Wars: Welcome to the Official Site</SearchTitl ...Show All

• Smart Device Development BYTE and WCHAR types

  Hi! My code reads data from file on pocket pc emlator into the &buffer variable.

• Software Development for Windows Vista DragDrop operation behaviour is changed in Vista

  Hi, In Vista dragdrop operation cannot be set to move. (i.e. DROPEFFECT_MOVE ) when UAC (user account control) is set to "on" If I set the drag drop operation to move then the drag drop operation prompts me stating "You will net to provide admnistrative permissions" and when accepted it confirms the action and I see a progress bar, but even after that the dragdrop operation is not succesful. If I set the dragdrop operation to copy everything works fine. Can someone tell me how to go forward. Thanks, Arun can you explain more about the origin of the drag operation, for example what process is originating this, is that process running at an elevated privlage le ...Show All
