• Smart Device Development Display data on datagrid without selecting data in database

  Hi, I am using VB.net and Visual Studio 2005 to compile a program for a Pocket PC with MicrosoftR Windows Mobile 2003 Second Edition. What I want to do is to display data on datagrid without selecting data from a database. I know that one way to display data on datagrid is to first select data from database using "sqlCeDataAdapter" and then fill the data into a dataTable of a DataSet. Finally this DataSet is assigned to the DataSource property of this datagrid. However, now I have three ArrayLists: AL1, AL2 and AL3. In these ArrayLists: AL1(0) = 3; AL1(1) = 2; AL1(2) =1; AL2(0) = a; AL2(1) = b; AL2(2) =c; AL3(0) = x; AL3(1) = y; AL3(2) =z; The result that I am expecting is: on a datagrid, these data can be displ ...Show All

• Visual Basic Custom Dialog Help

  I created Dialog1 in my current project. I cannot figure out how to get it to come up when my "New" button is clicked. The various ways I have tried all fail. Thanks for the help. Double click on the new button in the designer to create a click event. Inside put Dim dlg as Dialog1 = new Dialog1() dlg.ShowDialog() That will work. Now, go and buy a book to help you get over the initial learning curve that includes these sort of questions. We will be happy to help you either way, but you really need some sort of reference to accelerate your early steps, or it will take you ages to get past them. ...Show All

• Visual Studio 2008 (Pre-release) Export to XAML

  I made a drawing in a Canvas using code (I mean I used C# methods to draw lines, polygons, etc.) I wonder if it is possible to export this drawing into a reusable XAML file. (Something similar to Bitmap.Save() in Windows Forms is what I need).

• Software Development for Windows Vista Remote Desktop still an issue

  According to some MS documents (e.g. http://www.microsoft.com/whdc/system/vista/services.mspx), it should be possible to use CreateProcessAsUser() API in a Vista service to create a process in user session. I am trying to achive this, but the function returns error code 1307 (ERROR_INVALID_OWNER) = "This security ID may not be assigned as the owner of this object." Does it work for somebody Many thanks in advance. 123 is ERROR_INVALID_NAME ("The filename, directory name, or volume label syntax is incorrect"). Check the command line / exe path you are passing it. Also, keep in mind that Local System does not have privileges to access network paths, and does not have the mapped drives t ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Beginner transform matrices question

  Hello all, I'm trying to learn DirectX9 (unmanaged C++) from 3 different books and I still have a few questions that I can't deduce the answers to. I'm hoping some of the gurus here can shed some light on these subjects: 1) How does Direct3D know when I'm feeding it pre-transformed vertex coordinates If I neglect to implement D3DXMatrixPerspectiveFovLH (or any other transformation matrix for example) will Direct3D assume that the vertex buffer data is already in screen coordinates 2) I've seen, in my book, an example of a custom vertex structure meant to contain transformed data (it's introduced before the chapter on 3D transforms). It looks like the following: struct ColorVertex {    float x, y, z, rhw;  &n ...Show All

• Windows Forms WinINet.dll dependency

  I have created a setup project using VS .Net 2003 for one of my MFC applications. I am using WinInet API in that application and hence the setup project automatically picked up WinInet.dll as a dependency. But I am not sure if I really need to package it in the MSI. Can I safely exclude WinInet.dll and assume that it will be available in the target machines This will reduce the size of the build by 600K. I am targeting only XP and 2000 machines. If it can be excluded, what precautions need to be taken during installation Any help would be appreciated. Thanks ...Show All

• Visual Basic Saved variables--lots of them.

  Hello, I'm trying to make a program that works as a sort of daily planner. It's going to be very simple, but works on the fact that I will have "slots" for activities at half-hour intervals. When I have finished with that particular slot, a messagebox will appear and a noise will play. This is a personal project and I want to use it to help me not over-work (a strange thing I know, but I almost never look at the time ^_^) The whole thing will have differing amounts of "working" school loads (sport doesn't count as a studyable subject). To make matters worse, I want to add that I need some sort of way of storing notes, but I'll save that for a later date. Right now, I'm desperate to know how to dynamically save variable ...Show All
