Windows Forms Remove combobox items
I've got a combobox, cmbStartT with items (loaded at run-time) to represent time values starting from 07:30 AM to 04:00 PM. I want remove certain time values depending on what time it is on my computer. If it's 11:01 AM on my computer, I want to show only time values from 11:30 AM to 04:00 PM, no problem with this one. If it's 11:31 AM, show only time values from 12:00 PM to 04:00 PM. Dim sTime As DateTime Dim pos As Integer If cmbType.Text = "Meeting" And cmbStartD.Value.Date = Today Then For pos = 0 To cmbStartT.Items.Count - 1 sTime = cmbStartT.Items(pos) If TimeOfDay.Hour = sTime.Hour And TimeOfDay.Minute > sTime.Minute Then While pos >= 0 cmbStartT.Items.RemoveAt(pos ...Show All
Visual Studio Express Editions Linker errors when building samples...
Ever since I installed VC++ express I get linker errors when building any of the samples I've found in the "Microsoft DirectX SDK (December 2005)". It has been a long time since I have used C++ and thought I should give it a new try when I found it free here. But I can't get it to do any programming when the aplication will not work. I installed VC++ express, "Microsoft Platform SDK", "Microsoft Visual C++ Toolkit 2003", "Microsoft DirectX SDK (December 2005)". I am running Windows XP. I have set up the directories for bin, lib and includes for those packages.

.NET Development Generated TableAdapter does not create methods for manualy entered commands
If I create a tableadapter from a simple query, the corresponding Insert/Update/Delete commands are created, and the generated underlying class has matching methods created also. That's fine. However, I am creating a TableAdapter from a query using joins from multiple tables. In order to update the primary table, I have then manually written the Insert/Update/Delete SQL and set the appropriate paramerers. In this latter version, the generated TableAdapter class does NOT get the corresponding insert() & delete() methods created. Is there some way of forcing these to be generated, or some guidelines on when methods will and will not be generated Thanks in advance Tim No, i ...Show All
.NET Development Best Practice - Implementing Dispose / Exposing the Disposable Resources
I apologize if this thread is in the wrong forum. Our general rule of thumb is if our class owns a class level unmanaged resource or a managed resource that contains a Dispose method then we implement IDisposable on our class. So, for instance, we have a class level DataTable that we instantiate from within the class, since it has a Dispose on it, we implement dispose. No problem there. My question is, if we expose that class level DataTable that our class owns via a property, or return it via a function or even return it via a reference parameter....should we still clean it up via dispose We are divided here at our shop. I say no, my boss says yes. We are currently cleaning it up in the dispose. 8) My thought is we are sending t ...Show All

Visual C# Running C# Commands from a parsed text file?
Is it possible, say you have your main program, and when it initializes, it will scan this text file, looking and trying to execute all commands that are listed, like running a method inside the program, or if you put MessageBox.Show("",""); In the text file, or is there another way of doing this, I'm not going to make the program only understand commands that I put in it, through a switch statement, or if statements, I want it to directly interpret it. Checking out the built in C# Compiler, it looks like it would want me to have a seperate executable though, doesn't it Also, is this implicitly supported by the .net framework or is it with VS With a seperate Executable, I don't think ...Show All

Visual Studio Team System Searching work items
Hi Is there anyway I can search existing work items, say by title in order to find a possible existing work item For example, before logging a bug I need to know if anyone else has logged it previously. Or is this something I have to provide myself Thanks for your help Graham Hi You can do that. Create a new query and add the constraint title contains ' . In the team explore you can righclick on Work Items and then click Add Query. In the Query Form, leave the project row as it is, in second row select Title under field, select contains under Operator, type the text you are searching for under value then hit F5.

Game Technologies: DirectX, XNA, XACT, etc. Creating 3d Sprites slow down Device.Disposing...
hi, in my game, the particles that i create are slowing down the Device.Dispose(); the object Disposing in my game is done by the following steps: 1. the object dispose its vertex and index buffers, and set a IsDisposed boolean to True; 2. the Game read all Objects and set to null the disposed objects; when the game closes, before the Device.Dispose() it Dispose all the textures, the effects (my textures and effects are shared for memory reasons) and the objects. my debugging leads me to the conclusion that the objects remains after the .Dispose()... why You don't need multiple vertex/index buffers... Just create one set that describes a sprite quad and draw with it several times using different textures/s ...Show All

Smart Device Development Shell_NotifyIcon icon invisible when building with VS 2005 for PPC 2003 target
I'm using Shell_NotifyIcon to put a icon in the task bar status area at the bottom of the screen. The code works correctly when I build and deploy to a WM5 device using VS2005. You see the icon in the bottom of the screen and if it is clicked my applicaiton gets notified. When I build and deploy the same code and project to a PPC 2003 device the icon is invisible. I have verified that it has been place on the task bar, if you click where it should be my application gets notified. I verified that Shell_NotifyIcon is returning true, implying success. I verified that the icon handle is not null in the NOTIFYICONDATA structure. The icon I am trying to use includes 16 X 16 16 color and 32 X 32 16 color images. I tried adding 256 color ...Show All
