• .NET Development problem of callback function call C# to C++

  Hello, My problem is the following : - I have a DLL in C++ which is called by my application in C#, a callback function pointer is passed to this DLL in order to be called later for progress purpose. - It seems to be OK but when the C++ DLL call back the C# application using the callback function pointer, an error is raised.

• .NET Development How do you copy in a newer version of the current exe?

  I am running my app on a LAN. When I produce an upgrade, it is not feasable to run the upgrade on all the PC's, so I am wanting to check the version of each file I am using on statup, and compare to a central folder. Any file that has been changed in the central folder will automatically get copied. I then close the app, so the user will restart with the new versions. This all works fine, except I cannot copy in the new exe, as it is being used. Is there any easy way to copy this file in, either on exit, or on startup Also http://www.microsoft.com/downloads/details.aspx familyid=C6C09314-E222-4AF2-9395-1E0BD7060786&displaylang=en ...Show All

• Visual Basic while inputbox

  Hi, i'm using vb 2005. my question is: i have this code: Dim x As String = "" While IsNumeric(x) = False x = InputBox( "Enter a number" , "New Value" , "0" ) End While How can i exit a while statement if the user pressed the cancel button in the inputbox Thanks... Personally, I wouldnt use the input box for a number of reasons 1. Its not easy to determine between a blank string returned or cancel being pressed. 2. It doesnt permit you to validate the input prior to clicking closing the form. So I prefer to create my own dialog forms - which are very easy to create with a return property. I can call this dialog which is easy to ...Show All

• Windows Forms ClickOnce Deployment Issue - File Has Different Computed Hash Than Specified In Manifest - Urgent!

  Hello, originally posted this in the VB General forum - didn't get much response, so I thought I would post it here.

• Windows Forms Merging MenuStrips

  How are you supposed to create merge menus using the MenuStrip control in VS2005 Beta 2 I can't successfully get MDI child forms merge with the MDI parent using the merge index, and I'm not sure if I'm just not doing it right or if it is a bug. Can someone please point me in the right direction Merging with ToolStrips in significantly different than previous versions. Here are some guidelines... In the case of an activated MDChild, we automatically merge toolstrips to the MDIParent. You need to create the source strip control that contains the items you'd like to merge into the parent. There are two aspects of the source strip - it needs to contain the items to be merged and the structure to "match" ...Show All
