• Kishore Gopalan Process.GetProcessesByName can't get process info

  Hi folks, Process.GetProcessesByName works fine when it was running as an administrator, but it gives an error when running as a plain user saying "Can't get process information from remote machine." The operating system is Windows 2003 server Std, and the machine is configured to be a terminal server. Anyone help with this I am pretty lost, thanks. Thanks mate, It was running on the real system console. The code was written in VB.NET 2003, which targets to .NET Framework 1.1. The machine got both 1.1 and 2.0 I think. I've modified the app.config file to include both version of .NET Framework, but it still gives the error. windflower ...Show All

• TBrij Help removing menu item.

  I have code that scans a config file and when it finds a certin line it adds a new drop down menu item to File --> Configure --> "New Item Added" For example in the config I have a line that equals: Test = "Sample1" When the program loads and find the line with Test = "Sample1" it will add that item to the drop down menu under File --> Configure --> Sample1 this works perfectly. Now I also have an option to delete this item out of the config file and I am trying to get it to remove from the drop down menu. When you click the delete option you get a dialog box with a drop down that lists the items you can delete from the drop down menu that were loaded from the config file.

• GroZZleR Combobox question

  hello. A question please. If I add elements to a combobox manually, I mean for example combobox.Items.Add( "Monday" ) Can I associate a key to each element of my combox Something like this: ComboBox1.DataSource = datatable ComboBox1.DisplayMember = "long_name" ComboBox1.ValueMember = "id" Thanks in advance...   This is really simple and doesnt require databinding. If you implement any class (in my case ListItem) and as long as you have a Public Overide on the tostring method - this is what will be displayed in the listbox/combobox etc. When you retrieve the selected item - you can cast it to the original object type and access all the specific properties such as ID, Name et ...Show All

• FloridaJohn is it allowed to install Visual Studio 2005 non-express editions on more than 1 PC?

  At the moment I'm using VB 2005 Express. I'm considering upgrading to the standard or professional edition. However, now I'm able to use the express version on, for example, a pc at work and a laptop at home. Does this also apply to the payed versions Note: I'm the only programmer, so only one edition will be used at a time. Regards, Eric I believe for paid versions the answer would be no, not unless you have an MSDN subscription with certain licensing scheme or something, again, BEST to call the MS Support and confirm for sure, before finding a letter on your door! :-) It is rather dangerous to try and take individual items from a EULA and use them as a justification for you actions, as you may f ...Show All

• Ceres629 VB 2005 Window Stay On Top?

  I was trying to get my form (the main form Form1) to stay on top all other windows windows(such like the Windows Task Manager) but with no luck. I tried Google and came up with several approaches: One used the SetWindowPos API call but that generated some insanley cryptic message that the call '...unbalanced the stack...'. I also tried setting the form's TopMost property to true, but that only made the main form stay on top the other forms, in the the same project, not all other windows at runtime. So far I have nothing so if anyone had this problem before please say what I'm doing wrong (or not doing at all). Thanks in advance. -Will This code works correctly. But what I need it is that the code works for another ...Show All

• Puil Strings Class .substring(string.lenght - string.indexof(string))

  I am confused and or concerned about the difference between the value returned by .length (it counts CHARs) and .INDEXOF I want to parse off the right hand part of a string after the occurance of a substring and was thinking stringname.substring(stringname.length - stringname.indexof(findstring)) Being new to Unicode and 2 chars per character is the above going to get me in trouble INDEXOF returns the position in Unicode characters as I understand it. I suppose this sounds confused but I AM confused by all this Unicode and CHAR mixing in the strings class. Doug W   Doug Wyman wrote: Thank You!  I appreciate a direct reply that answers my question.
