• Visual C++ Microsoft Dynamic Link Libraries (dlls) - What ones must be given to the end user?

  Compiler: Visual Studio.NET 2002 Hi everyone, You will probably think I am a bit dim for asking this question but it is one that does confuse me. How do I know what standard Microsoft dlls (Dynamic Link Libraries) must be sent out with my software so Windows users (even the previous Windows release users) can use my programs I was going to link statically (as I got the impression that doing so would automatically put the dll in the final executable). Then I got some errors which got resolved when I linked dynamically instead. So even though the optimal answer would be to link statically, please answer assuming I link dynamica ...Show All

• Software Development for Windows Vista play a stream

  Hi,i have the following problem: My computer(client)is connected to a server using a socket.The server sends an avi stream through the socket.How can the client play this avi stream....without saving it on the harddisk Any ideas....sample codes....anything.Thanks You'll need to write a source filter to read the data from the socket and deliver it to the decoder filters. You'll probably want a push-mode source filter (modelled on something like the ball sample), that splits the audio and video and delivers them to the decoders on separate output streams.

• Windows Forms Updating files with mage.exe doesn't work

  I'm running a batch file to create a deployment with the following commands, between version's of my .exe I copy trailblz.exe into my \bin and 1 in 5.0.0.1\trailblz.exe.deploy, when I run the following batch everything appears to be fine, except when deploying, I get errors because the trailblz.exe.manfest still contains the old version of the .exe.

• Visual C++ Region Resource leaks in C++ MFC project developed using VC7, Dotnet framework 1.1

  I am facing some resource leak problems with my application. During investigation i found that the app was leaking a lot of regions. I was suprised since we did not explicitely use any regions in the app. So just to find out more I built a sample wizard generated VC7 C++ MFC project, Dotnet framework 1.1 on Windows XP After invoking the application, Opening and closing the document window introduces approximately 6 GDI object(Region) leaks each time.  Even more puzzling is the fact that the same application run on Windows 2K does not leak at all. I have not been able to understand the reason for these leaks or how to circumvent the ...Show All

• Windows Forms Invalid Operation Exception while installing from CD

  Visual Basic 2005 Express Edition: My app works fine on my computer. I published it to a CD using ClickOnce, specifying that the prerequisites be downloaded from the internet. I attempted to install it on another computer. It immediately aborted with an Invalid Operation Exception in my app. I installed it on my computer from the CD, and it ran fine.

• Visual Studio 2008 (Pre-release) XBAP and default browser

  Hi, I got the following problem since I uninstalled the February CTP and installed the May CTP instead: When I press Ctrl-F5 in Visual Studio for a XBAP application, Firefox is started instead of IE. Since Firefox doesn't understand XBAP, I cannot run or debug the application as easily as before. I know how to change the default browser for a HTML application, but I didn't find such a setting for XBAP applications. Any hint welcomed! Greetings, Laurent In your explorer, go to the .xbap file and rigth clic on it. Select Open With and choose IE. Check the checkbox "Always open ..." I think it will do the trick: I ...Show All

• Visual Studio Express Editions Reference Dataset in Another Form

• Visual Basic Cross thread call error

  I am using VB.NET 2005 I have the following application structure: UI form, a middle layer and a low level layer. They are all running in the same thread. The low-level object creates a serial port (the .NET one): New SerialPort(port, 57600, Parity.None, 8, StopBits.One) and handle its events. Some of these event handlers throw events that are handled by the middle layer that in turn throw events that are handled by the UI. The serial port is running on a different thread than the application and hence the event handlers are not running within the low level's thread. The end result of the chain of events mentioned a ...Show All

• Software Development for Windows Vista Architectural question about WWF

  Hi there, I'm just investigation the possibility to use WWF in an Orderrouting System. The system has relatively huge number of different routing objects (orders and group of orders) (about 100k objects). The system works in PUSH mode, means every workflow state transition is forced by event (like insert, update, delete of objects). My question is. What is the best use of the WWF components in this case 1. Having a stand-alone Workflow server, listening for user events. In this case, middle-tier will notify Workflow server that an order is changed and force workflow to continue. Is it possible to have 100K workflow instances ( ...Show All

• Windows Forms Binding to RichTextBox

  Using VS 2005 Beta 2, VB, SQL Server 2000 I have an existing SQL table with a field 'Comments' of SQL datatype 'text'.  The data stored in the field was created using the RichTextBox under VB6. I use a Data Source/Data Set and set the Comments field to RichTextBox.  When I drag the control onto the form a RichTextBox is created but the control displays the existing RTF as text. I expected a RTF under DataBindings but did find it there.
