• Visual Studio Express Editions Background task (daemon)

  How do you write a program that does not open a console window or a win32 window In other words, a program that runs without displaying anything on the screen I know how to do it with VC++ 6.0, but I can't figure out how with Express. Best regards, Jive Alternatively, you could create a Windows application where instead of having int main(void) as your entry point you use: int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int nCmdShow) { return 0; } This function is usually used to create a window. In this case, we're not bothering to create a window. ...Show All

• Software Development for Windows Vista ListenAcitivty won't work with custom Activity

  I created a custom Activity that has a callExternalMethod then a handleExternalEvent Activity. I would like to use this custom Activity in the ListenActivity but the validator is preventing me from adding it. How should I approach this 1.) subclass ListenActivity and override the Validator 2.) Create a new compositeActivity that behaves like ListenActivity(more work,leads to more questions) 3.) I have implemented that as a second control as a stopgap. however, I want to make it easy for other developers to add another branch.We may have 3,4,or 5 branches and I don't want the other developers worrying on how to modify/create an activity.I'm turning over my solution to another team and I think it ...Show All

• Software Development for Windows Vista Project type is not supported by this installation

  I have been struggling with this the entire day. I just installed for the first time: WinFX Visual Studio 2005 Extensions for Windows Workflow Foundation Beta 2_2 Windows Workflow Foundation Runtime Components Beta 2_2(EN) for x86 WorkflowTemplates - 2006-03-07 If I try to create any WWF project based on the new templates, I receive an error stating that "the project type is not supported by this installation".

  Has anyone here worked with the Metastorm workflow product I'm trying to get some information on Metastorm vs. WWF (or SharePoint 2007 workflow).

• Smart Device Development .NET CF Sockets using ActiveSync

  Hi, I have big troubles trying to use .NET sockets between a c#.net desktop application and a c#.net cf application. When I use the VS emulator the sockets do work without problems, but when I use a real device (using ActiveSync) I get the error : "Socket error Resource-assembly could not be found". I know I didn't make any "coding" errors because I use the exsisting program "Desktop Signature" which uses sockets between a desktop server app and a clientside pocketpc app... So I think it has something to do with my settings of my PDA or settings of VS.NET... I searched the internet to solve the "resource-assembly" error, I found I was missing the language cab to print the error... I did not ...Show All

• Visual Studio Express Editions Form Resize

  Hi I downloaded the SmartResize dll (written in .NET 2.0). I added a Flowlayout panel and added multiple RichTextBoxes dynamically depending on the data I have. When I resize the window I use ContentResized event of RichTextBox to calculate the minimum height of the richtextbox, which works great. But unfortunately when resizing the form window sometimes one or more richtextboxes do not rtesize properly. Any idea why this happens I see that richtextbox1.Width = new_width is not taking the new value. Is it possible that the control is busy and not ready to accept new values If so how to fix this problem. Thanks a lot. ...Show All

• Visual C++ Windows Live Messenger requiring msvcr80.dll!

  I'm using Windows XP Professional with Service Pack 2 (Swedish). I guess you have an old version of that dll in the directory where your live messenger is installed so that is loaded before the correct installed by vcredist can be found. Do you know in which directory the live messenger is installed If you find a msvcr80.dll in that directory, rename the dll. Call it msvcr80.dl_ Restart the live messenger. If you do not know the path, get process explorer( http://www.microsoft.com/technet/sysinternals/Utilities/ProcessExplorer.mspx ), find the live messenger exe in the list, move the mouse of that entry, wait for a tooltip showing the path. -- SvenC ...Show All

• Commerce Server Free Items Issue

  Hello, I have an issue that I am trying to resolve with our Commerce Server 2007 site and was hoping I could get some guidance. We would like to be able to add free items to our shopping cart, but would like to avoid having to add a new discount in Marketing Manager per product with free items since there are thousands of products in our catalog that fit this criterion. This could make prioritizing discounts painful with such a large number. Some additional shopping cart logic was added by one of our developers to use the product relationships table for free items, search the table when a product is added to the cart, and add any associated free items to the cart as well. The problem with this is that the items get added t ...Show All

• Visual Studio 2008 (Pre-release) plug in model

  Its documented that Wpf doesnt support the plugin architecture. So is there an alternative. our team is currently planning to develop a prod which would involve third party plug ins. We would appreciate if some code is provided to see how feasible it is to our requirements. There are a few blog postings that discuss creating a plugin architecture for a WPF application. One developer even combined the Composite UI Application Block with WPF . I haven't looked at it myself, but the implications are phenomenal. Another place to look is the Rioterdecker's blog . I believe they have some interesting posts on plugin-based WPF applications. ...Show All

• SQL Server OLE DB Source using table name variable

  I have a package-level variable [User::viewName], type = string, containing a view name. I want to setup an OLE DB source to use this variable value as the source, so Data access mode = "Table name or view name variable". The Variable name dropdown contains [User:viewName], so I select it. When I click OK to leave the edit dialog I get the error: The variable User::viewName is required to be of type "VT_BSTR". Only variables of type String occur in the Variable name dropdown; if I try changing it to a type other than string it doesn't occur in the dropdown. What is VT_BSTR and how can I change the variable type to it This error can occur if you assign NULL to a string variable, f ...Show All

• .NET Development Iterate Network connections list in c#

  Is it possible to read through the list of existing dial-up and vpn connections in windows xp with c# I would like to have a script that would create a set of default connections for remote users.
