• .NET Development Problem with Type Converter

  Hello, I am experiencing a design time problem while designing a control. I have designed a Custom Web control 'DataProvider' which has a 'DisplayPanelDataSources' collection property which contains a collection of WebControls which are used to define data source for each 'DisplayPanel' Web custom control as 1 to 1 relationship such as: ------------------------------------------------------------------------------------------------------------- DataProvider ---|------ ID |------ DisplayPanelDataSources ---|--- DisplayPanelDataSource1 |---- DisplayPanelDataSource2 ...Show All

• Visual Basic Register for COM interop

  Ok, I have done a standard DLL project, I select the “Make assembly COM visible” I set “Make COM visible” to true. I go into the properties and select the Compile tab but I don’t see the “Register for COM interop” option anywhere. Anyway, I register the DLL with the RegAsm.exe using the /TLB switch, this goes well, I know make reference to it in AutoCAD VBA this also goes well by selecting the *.tlb I created when I registered. Now if I try to use any part of the reference in the VBA application I get an error. Can anyone guide me in the right direction Thank in advance. William Apopka_ ...Show All

• Windows Forms DataGridView Calling EndEdit when row is removed

  Hello, First I will tell you how to recreate my problem: First add a datagridview to your project and add a couple of columns. Then add a timer with a 2000 interval. In the timer tick event write code to delete the first row of the datagridview. Add a button to start the timer. Start the program add 10-15 rows to the gridview, then start the timer. The timer of course will start to remove rows on the top. Go into edit mode on any row below the first. When the first row is deleted it will throw the gridview out of edit mode. This is extremely frustrating considering I am building a client/server program where anyone could delete a row, and on ...Show All

• SQL Server What is the difference in WM5 windbase.h and windbase_edb.h ?

  Hi all, I am having a hard time with WM5 edb. I saw some post to use "windbase_edb.h" header file, and the "Porting CEDB to EDB" use "#define EDB ..windbase.h". It is very strange that using difference headers, the parameters of default structures are not the same (i use the debugger to observe the values) "windbase_edb.h" CEDBASEINFOEX     DBInfo; the sortspec of DBInfo defaults to [4] ------- this is the old CEDB default "#define EDB "windbase.h" CEDBASEINFOEX     DBInfo; the sortspec of DBInfo defaults to [16] ------- this is the EDB default I ...Show All

• Visual Basic Publishing an EXE

  In Visual Basic 6.0, you could publish your program directly to a single .exe file. Now with Visual Basic 2005, I'm having some difficulty doing that. When I select 'Publish', I get to a wizard. When I click 'Next', however, it asks me where I want to install from.. Does this mean I don't have the publishing wizard installed Anyways, what I've been doing is selecting 'Back' from there and saying 'Finished'. This creates a few (usually three) weird files, including a setup file and an 'Application Manifest'. When I run either one, it asks me to install it.. So I let it, and the program will run then. However, I have to install it every time I ...Show All

• Smart Device Development CF2 - Closing a form with an embedded WebBrowser closes my entire app

  I've been programming in the UNIX world for years, so I'll admit that I'm fairly new to programming Windows Forms and CF... but this seems definitely idiosyncratic and I was wondering if anyone knows of a decent workaround... I'm using an embedded web browser control to display formatted text output of variable length (it seemed the only fairly straight forward way of doing it for Windows Mobile 5), but when I call the form.close method, my entire application exits. Everywhere else I've ever used this, it returns me to the perviously-open form before it in the navigation stack. I've 'worked around' this by calling form.hide here, instead, ...Show All

• Windows Forms Databind to collection object

  I've created a customized collection and want to databind it to a DataGridView. After some research, I found that I need to create a bindingsource control and then bind to the specific collection object. The first problem is that I need to retrieve the collection instance for some additional method calls. How can I get the underlying collection instance back I found that the databingsource will use BindingList<T> as its internal store. How can I convert it back to my specific collection so that I can make additional method call your custom collection should inherit from BindingList. . . if you have a class FooBar. . . and a ...Show All

• Visual Basic Regions bug

  Every day after I’ve been working in the IDE for a while, the collapsed #regions will not open with a single click on the plus sign anymore. Instead it takes 5 to 10 clicks to open them. Actually in different source code files it takes a different number of clicks in order to un-collapse a #region . (but always the same number of clicks within the same source code file) I sure hope this will be fixed soon. It's been doing this all along since I switched in February. Any idea what's causing this Which versions on VB are you using.... VS Studio, VB Express Has it been doing this f ...Show All

  I really hope this is possible, because it seems to basic. I would like to know all the files that have been updated since the last time I synced with my source safe database. If I do "Get Recursive" on my top level project it simply updates the files, and doesn't even tell me which ones.

• .NET Development Registering events dynamically with a remote object

  Ok where do i begin... well i am trying to come up with a solution to allow me to register event handlers with an event dynamically. Consider the following code if (aEvent.Name.CompareTo("getFilesCalledEvent") == 0) { Delegate myDel =Delegate.CreateDelegate(aEvent.EventHandlerType, this, "EventCalled"); aEvent.AddEventHandler(this, myDel); } As far as im concerned this should register the method EventCalled contained in the running instance of the object pointed to by (this). When executed i get the exception "Object does not match target type", when i call the AddEventHandler Method. As far as i can assume ...Show All
