• Microsoft ISV Community Center Forums Serial Port communication from Excel 2003

  I am trying to write a simple VBA macro that reads Text data from a Serial port and puts it into an Excel 2003 spread sheet. The solution needs to work from a standard installation of Office 2003. I cannot use add-in modules since the envrioment has been locked by the SysAdmin. Can I make calls to windows API to communicate with the port from Excel Is there some sample VBA code that shows how to do this ...Show All

• .NET Development .Net 2.0 release version breaks VS 2005b2?

• Windows Forms DataBinding - Hardcoding ValueMember and DisplayMember

  Something that always bugged me about data binding in Visual Studio is that you specify the DisplayMember and ValueMember of the binding to be strings that are *supposed* to be properties of the data source. You get no intellisense help when entering these values and, if you spell it wrong or the name of a property changes later, the project still compiles and runs fine until you hit that binding. Is there a way, using reflection or any other m ...Show All

• .NET Development Execute a list of SqlCommands

  My client/server architecture is designed in a queued fashion: the client may send many messages to the server, and from there, the server will create SqlCommand objects, and execute each one in SQL server. What I'd like to do is find a more efficient way to execute lots of commands; currently, I do: // open a connection SqlConnection connection = new SqlCommand(...); // create a command SqlCommand command = new SqlCommand("DoSomething" ...Show All

• Visual Studio Local Variables invisible to debugger?

  Recently the VS2005 C# debugger has been exhibiting strange behaviour. Here is an example: private void Test() { double dd = 2.0 * 3.0; return; } Up until recently, I could set a breakpoint on the return statement and place the mouse over the "dd" variable to see its value. Also, I could open the "Locals" window and see "dd". All of a sudden, the local variables are "invisible" to the debugger. Nothing shows up when I hover the mouse over ...Show All

• Visual Studio Express Editions Command object

  In Visual Basic.Net 2003 there were oleDbCommand objects which I used to create a select statement. I then created an oleDbDataReader in code. The command object then executed the reader object which I used to fill my comboBox with items. I did this so that I could update the items in the combobox from another form and so the comboBox would put the string in my database field and not the ID. My question is: I don't see the command object and ...Show All

• Visual Studio 2008 (Pre-release) "yield enumerate"...

  (Slightly off-topic, but it at least deals with enumerations.) Lately, I've found myself using the following pattern: public IEnumerable<T> Foo(IEnumerable<T> values, IEnumerable<T> moreValues) {     foreach (T t in values)    {       yield return t;    }     foreach (T t in moreValues)    {     &nb ...Show All

• Visual FoxPro how can i get the current active control's name in a form?

  thank you Jet Hi Jet, if you don't don't need the name of the control inside a grid you can use code like this to get the name of the active control: IF TYPE("Thisform.ActiveControl") == "O"   lcName = Thisform.ActiveControl.Name ENDIF It's important to check the type beforehand, because the ActiveControl property doesn't exist if there's no active control. For grids this code would return the name of the grid, not the name of the ...Show All

• Visual Studio "Start Debugging" vs "Start without Debugging" speed in VS2005

  I experienced extremely slow performance in VS2005, when I "Start Debugging" an application which uses System.Drawing.Bitmap (might be anything that uses interop, but that's just my wild guess). Everything is fast if I "Start withoug Debugging" and it does not matter if I compile a release or a debug version. Please check this little piece of code: namespace ConsoleApplication1 { class Program { static void Main( string [] args) { Syste ...Show All
