• Smart Device Development pictures giving me trouble

  to start off I have 2 hand helds, one has a resolution of 480X640 while the other has a resolution of 240X320. I am developing a system using pictures throughout. The problem that I am running into is that I cannot make the pictures fill the screen. If I develop the images for the smaller one, they show very small on the larger one. and if I design my pics for the larger one, they are to big for the smaller one and it cuts part of the picture off. What I am wanting to do is be able to design all the pictures for one (either or) and make the pictures shrink or enlarge to fill the screen. Both hand halds are Ipaq. if that makes a difference ...Show All

• Windows Forms CheckBoxColumn Problem

  Hi, I'm using Visual Studio 2005, with C#. I have a datagridview with a modified checkboxcolumn, I have a class that inherits from Checkboxcolumn, and add a textfield to it. My problem is that when the user selects the checkbox the datagridview automatically adds one new row to the DataGridView. Any ideas of what might be wrong Thanks in advance for your help. Regards Luis Filipe de Sousa Hi. Actually the problem isn't with my custom control. I'm using the grid in the unbound mode, and I always got an extra row at the end of the grid. I checked my datasource and it don't have an ext ...Show All

• Visual C++ Trying to reset USB port

  I have some custom built computers that must have something wrong with the USB ports.  About 80% of the time when I turn the computer on only half of the USB ports detect a device and I have to manually unplug and re-plug the devices plugged into bad ports. I would like to write a small utility that upon start-up will iterate through the USB ports and disable and then re-enable them. I can't find too much info on this elsewhere.  I apologize if I am asking in the wrong forum.  Thanks very much, Taylor devcon is a command line utility which can disable/enable any device. I discovered that some older NEC chipset 2- ...Show All

• Visual Studio Creating SQL Server Project by automation issues

  I'm trying to create a SQL Server Project by automation. So I started prototyping using a Macro. I know the connection string for the project so I don't need that the "Add Database Reference" dialog appears. So I created my template with a connection string that after I need to set by automation. 2 issues: 1- When I use Solution.AddFromTemplate(...) the "Add Database Reference" appears. I suppose that the problem is that the ConnectionString is not stored in the csproj, it is stored in the csproj.user. 2- After I created the project the "Connection" properties does not belong to the project.Properties collection. Is there a way to do t ...Show All

• Windows Forms What is the proper way to change what ListBox.Items holds?

  In an effort to get rid of VB6.Get/SetItemData from a VB6 project upgraded to .NET, the project has been changed to use custom object classes (e.g., with Name and Data members) in collections. This works fine, but has the performance-overhead and type-unsafety arising from the ListBox.Items member being a generic ObjectCollection . What would be better is to create a subclass of a Listbox that is exactly the same as a normal one, except with a type-safe collection for the Items member instead of a generic object collection; that is Items should be a System.Collections.Generic.List(Of SomeType ) rather than just an ObjectCollection . I have ...Show All

• Visual C# "Layer of Abstraction" Confusion

  Hi folks, I'm trying to understand what events are, and primarily, why and when to use them, however, I'm having a little trouble understanding the subject. I hear a lot of people saying that events are another layer of abstraction, but I don't actually know what that means. I've tried Googling around, and I have found some sites that discuss it, but they seem to be talking to people who are CS graduates. Could someone explain the concept in simplish terms to me please I hate the fact that I'm shying away from what seems like a major language feature. Thanks in advance. Hi, As I see it, the ...Show All

• Visual Studio Team System Need more inherent labels

  TF teases use with the cryptic version spec "T" but I want more.  In general I would like to see more "inherent" labels and make them more readable than "T".  I want HEAD (what you call Tip), BASE (unmodified version of file in my workspace) and PREV (from BASE back to previous changeset).  Pretty often I would like to be able to do this: tf diff /version:BASE~HEAD foo.cs BTW, "tf diff /version:T foo.cs" doesn't work because it diffs against my modified version.  I have to figure out the version of BASE and do this: tf diff /version:C40~T foo.cs Blech!!!!  Common scenarios should be easier than this.& ...Show All

• Visual Basic Problems installing VB6 program onto other computers...
