• Visual Studio Express Editions Solution Questions

  I have a database that I need to design a GUI and a few database entry functions.   I am wondering if VB is the correct rout to go.   I am using Access Database for the database, though looking at using SQL Server Express.   The GUI will consist of a MDI form with several forms.   The main form is a form with a tab container in it.   The information shown on that form will come from several tables in the database, but only one tables info is directly editable.   The other info is updatable through other entry forms.   There is also a search form,   and mass addition form.   I will need to be able ...Show All

• Visual C# How do I tell when all threads in a pool are complete

  I have an app that uses a thread pool to ping all hosts on the local network. Each thread updates a listview with the status of that IP - alive or dead. When all the threads are done, I want to remove all the dead links from the list view. How can I tell when all the threads have done their job What is the best way to loop over the listview backwards (I assume backwards is best since the items are indexed...), removing each dead link (text in column 1 = "dead") Thanks in advance. Create an integer that stores how many threads are running. At the beginning of the threads that need to be ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Unmanaged DirectX with Managed C++

  I have been reading about the .NET framework for quite some time, and I found that Managed C++ allows mixing unmanaged and managed code. I've got a few questions about that. Is it possible to use an unmanaged API (like unmanaged DirectShow or DirectX) in a managed application If so, are there any steps that need to be done to do this Are managed API's like DirectX.NET also availible for Managed C++ If so, how do I know if I'm using the managed or unmanaged API Now I've also got a problem with DirectShow. I installed the latest Platform SDK and tried to include <dshow.h>. When I did that, it said I needed <ddraw.h>. Since directd ...Show All

• Visual Studio Express Editions Is it possible to shell an application seamlessly?

  I need to be able to run an application such as notepad or calc in the same way that I can start a browser inside my VB app ie. make the spawned program appear to be just another window in my program. Has anyone done this before   This isn't what's happening. The Webrowser control has been supplied as a wrapper for the Active-X webbrowser and you are using that. There are no such analogs for the utilties you mentioned.     ...Show All

• Windows Forms deploying under microsoft iis sharepoint services

  Hi, I would like to use the ClickOnce Deployment on a Windows 2003 Server where Windows SharePoint Services are running. I've tested the deployment on a Windows XP Professional PC with IIS which worked fine but is not applicable since the PC is in use as a Workstation.

• Windows Forms passing variables to form

  I made my textboxes on form1 public. I was able to access them through my form2, after I made a statement like form1 form2 = new form1();   Problem is, the text boxes are all empty on form2. Is this because I initiated a new form1 and therefore the textboxes are set back to their default as empty How can I access variables stored in form1 from form2 thanks. To have one form talk to another, pass the Form as an argument   In class Form2, write a method like   Public Method(Form myForm1) {             myForm1.TextB ...Show All

  When I right click on an instance of a RichTextBox control no menu pops up.  The standard (like cut and past) operations will be extremely useful.

• SQL Server Problems Using Temporary Tables

  I am declaring a temp table in control flow via Execute SQL task. I then want to use that table as a source in a data task, keep it alive going back to control flow and use it as a destination in another data task following. I am having trouble just getting the first data flow to access that temp table. In my Execute SQL task, I'm creating a simple temp table. After executing that task, I can head to the data task and change my OLE DB Source to point to that temp table, but I recieve an error about an invalid table name when I attempt to map columns or hit "OK." Is there something else I need to do to use that temp table as a sour ...Show All
