• Windows Forms If designer with new control crashes -what to do?

  I modified control, that was already instantiated on the form. After rebuild solution, form designer can not open form - due to exception that it cannot deserialize control. how to handle this situation thanks To avoid losing work, you obviously need to find out what is wrong with the new control that causes the designer to crash. AFAIK, normal Windows controls persist in the CodeDOM generated code, not resources. I wouldn't know about the custom control that crashes of course. Deleting any reference to the control in the designer file should work. There's usually a line at the top of InitializeComponents to create the control and several lines below it to set its properties. Plus a Friend d ...Show All

• Visual Basic Coerce a byte string to a structure?

  I have a file that contains a series of packets. I've created a set of structures that map the elements of the packets. My question... Is there a technique in VB to map the string of bytes read from the file to the structures In 'C' this would be simple. In VB.NET I don't know. Suggestions are appreciated. Thanks, Johnny Johnny,  there is something in the Interopservices that you may be able to use. I'm not sure what the overhead will be compared to just bitconverting the values out. Also, having arrays in your structure will be a problem / unknown length Anyways, this technique copies your managed bytes back to unmanaged memory and marshals them back into a managed structure. That goes something like this: Imports ...Show All

• SQL Server Cannot install SQL Server Express

  My system had a beta version of Visual Studio 2005 Express on it which I uninstalled. Apparently not correctly, as I can not install SQL Server 2005 Express. I have tried to removal procedures which either give me an error message or I cannot find the items in the Add/Remove program list that are requested. That is, it looks like the system should accept SQL Server 2005 Express, but it does not. I have successfully installed Visual C++ 2005 Express. I have no clue as to what to do next and there is no documentation on what to do. I have looked at the various postings here, tried several of them, to no avail. When I search the registry there are some 70 entries that have the string “SQLEXPRESS” in the entry. I am u ...Show All

• Visual Studio Team System Application Verifier with Unit Test projects

  I find the Application Verfifer a very useful tool. I also like the Unit Testing support that comes with Visual Studio 2005 so we write our tests using managed C++ which calls our unmanaged C++ code which is built as a static library. However, we can't find a way of running a Unit Test through the Application Verifier in the VS 2005 IDE. Is this possible We resort to doing it outside of the IDE by using the standalone version 3.3 of Application Verifier to instrument mstest.exe itself and then run the Unit Tests from the command line i.e. C:\Program Files\Microsoft Visual Studio 8\VC>mstest /testcontainer:"\TestProject1.dll" /noisolation Is there another way Application Ver ...Show All

• Windows Forms ParentControlDesigner.OnDragDrop: BehaviorDataObject?

  I've implemented a custom ContainerControl (designed by a custom ParentControlDesigner).  My design environment consists of the standard DesignSurface hosting my root component, a custom Form (designed by a custom DocumentDesigner).  I need to be able to drag/drop controls as well as string objects onto my ContainerControl so I've overridden ParentControlDesigner.OnDragDrop to check which is being dropped onto it.  Dragging from the toolbar to the form works fine, as I use GetData(typeof(ToolboxItem)) to deserialize. The problem I've encountered is I cannot drag a custom control already in the surface onto another of my custom controls.  The IDataObject in the DragEventArgs always returns 0 formats from ...Show All

• Software Development for Windows Vista Still confused - installing machine wide data for read/write all users

  Okay guys, Where in the world am I suppose to put our shared machine wide database on VISTA so that all users can read/write to it It is just a simple Access 2000 file. It shouldn't be this hard to put a file on a computer so all users can write to it. Thats all we want to do. I posted this about 3 or 4 days ago in another forum and a user said that we should be putting the database in CSIDL_COMMON_APPDATA if we want to share it with all users. So I followed these instructions and implemented the SHGetFolderPath API and I utilized this location (which maps to c:\programdata on VISTA) to store our database in c:\programdata\[ourApplicationName] Even though my data is written to this location each user that accesses the file r ...Show All
