• Visual Basic Calling forms/content across projects in multi project solution vb2005ee

  I built the whole project as seperate project files. Now i have to call forms from the menu of a master project form. HELP! regs, ehmer Hi, Take each EXE file out of each PROJECT's BIN folder and call them from your menu as follows.>> Just remember to put the full path to each file in each MENU Sub. Or you could just put the FULL PATH string in for each PROJECT's executable ( exe ) file. Private Sub MenuItem1_Click( ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MenuItem1.Click Process.Start("C:\Graphics-Demo.exe") End Sub   You may wish to put a copy of each EXE file in one common folder like into your MASTER project's fo ...Show All

• Visual Studio 2008 (Pre-release) Listener won't accept new channel after first one is finished

  Hey, I posted regarding my custom transport, and the including of security the other day. I solved that problem but it seems like the adding of security caused some more trouble. This is on the server side, where a ServiceHost is used. Without security this was what usually happened (using reliable messaging though): In the Listener, OnBeginAcceptChannel() is called, and an async setup of communication is done. When ready OnEndAccept() is called, and a ReplyChannel is returned. On this channel ReceiveRequest() is called and a RequestContext is returned. Using the RequestContext.Reply() a reply is sent. Back to (1), where a new channel is created for the next message... Now, with security, BeginReceiveRequest ...Show All

• Visual Basic How can you set variables to Nothing when using Return?

  Here's a hum dinger.... It's my understanding that it's good programming practice to set variables to nothing when you are done using them, however, how are you supposed to do this when a return statement is involved.  It's a catch 22... you cannot set the variable to nothing before you return it, and you cannot set the variable to nothing after you return it because no statements after "return" run. e.g. Public Function ReturnSomeCrap() As Crapola Dim SomeCrap As Crapola SomeCrap = New Crapola("100 lbs") Return SomeCrap End Function So, where and how do I set SomeCrap = Nothing, since I have to have it to return, and I cannot do it after the return Actually, in your example, you are not done with it: ...Show All

• Visual C++ Different behaviour of MainFrame on different computers!!!

  In my windows profile Windows Classic style is set. My application has no scroll control here. But when it is run on computers with XP style windows, it gets a big vertical scroll to move my View up/down. I really don't want no scrollbar on my application. First thing I did was to set FALSE parameter in View's InitInstance here:  GetParentFrame()->RecalcLayout(FALSE);  ResizeParentToFit(); ... but, it did nothing to remove my unwanted scroll! Then I tried this piece of code:  CRect r;  GetClientRect(r);  SetScaleToFitSize(CSize(r.right, r.bottom));   .. and that removes the scroll, but now left side of the mainframe is empty, and there is just about enough space left ...Show All

• Visual Studio Team System TFS SP1 and problem with get latest version

  Hello, I have installed TFS SP1 and have got the problem with VersionItems table. When I try to do "Get Latest Version" operation the error occures in rpc_Get stored procedure. It says that there is a collation conflict (SQL_Latin1 and "normal" Latin1). The stored procedure is encrypted so I cannot know what it tries to do. All other operations (check in, change workitems, etc) seem to work notmally. Can anyone help me and explain how to fix the problem Thank you. I have discovered that all the TFS databases are in "Latin1_General_CI_AS" but tempdb is in "SQL_Latin1_General_CP1_CI_AS" So when temp table #versionedItems is created in tempdb it is in default for tempdb collate: "SQL_Latin1_ ...Show All

• Windows Live Developer Forums Determine if Pushpin Exists

  Can someone share with me the correct way to determine if a pushpin exists before adding it I see that there is a "pushpins" class that has an "exists" property, but it is always returning false for me. I am looking to do something like the following: if(map.pushpins.exists(myPushpin)) { //its already on map, do nothing... } else { //code to add it... map.AddPushpin(myPushpin) } Thanks a million! What exactly are you trying to do overwrite an existing pushpin Why not just remove the pushpin at that location, and then put the one you are trying to insert I'm not aware of this exists property for pushpins, sounds like something that hasn't been released yet. ...Show All
