• Smart Device Development JPG image loading and rotation on Pocket PC 2003

  I have developed an app on PocketPC 2003 using VS2005. This application interfaces with a camera and retrieves JPG images from the camera. The app displays the images as thumbnails and allows the user to click the thumbnail to get the full size picture in a scrollable window. This all works fine, however loading the JPG is slow and rotation (the way I am doing it blows out the memory, no leaks that I can find. Image size: 2048(w) X 1536(h)). I am using imgdecmp library to load the JPG image to a DDB bitmap, and implement rotation by converting the DDB to a source DIB, then creating a destination DIB with rotated dimensions, then copy the source DIB to the dest. DIB, one pixel line at a time (very time consuming). When I use the Pict ...Show All

• Visual Studio Express Editions how to compare two images and return the result?

  Hi, all, I want to compare two images. I read these two images into the bitmap class If I don't want to compare these two images by each pixel, how can I compare these two images thanks for your help! Tsai Dim imagefile1, imagefile2 As Bitmap Dim result as boolean imagefile1 = New Bitmap("D:\temp\IMG_0315.jpg") imagefile2 = New Bitmap("D:\temp\IMG_0313.jpg") result = equals(imagefile1, imagefile2) // If imagefile1 and imagefile2 are really the same, but the result of the equals(imagefile1, imagefile2) is false why I am wrong. Didn't think about it till last night in bed. If you try to read two different file types (i.e. bmp and jpg) then the headers will automatically mak ...Show All

• Visual Basic "Start external program" no longer works in VS2003 once 2.0 framework installed

  Ever since I installed VS2005, the "Start external program" feature in VS2003 in Project Properties-->Configuration Properties --> Debugging does not work anymore. The external program launches for a moment, then bails out of memory with no apparent error. Removing the .Net Framework 2.0 fixes the problem. The only other person her in the office with VS2005 installed has the exact same problem. Removing the 2.0 framework worked for him as well. Any thoughts on how to get the feature working again WITHOUT removing 2.0 Marcus Just a guess, but if your external program was running with the 2.0 Framework rather than the 1.1 Framework then the 1.1 Debugger probably wouldn't like it very much. ...Show All

• Visual Studio Tools for Office performances problem

  hello When i transfert 12000 lines of a collection to a listobject on a worksheet with datasource and databinding, time transfert is about 150sec. with a 3G computer. If i transfert the collection to listobject with range and array, time transfert is about 2 sec. where is the problem regards Hi In order to tune the performance there are a few things which you can try: 1. Switch the LCID proxy off by setting an assembly level attribute ExcelLocale1033(false). There if an issue if you turn it off and thats why VSTO choses to keep it on by default. Read more here . This should give you a significant performance boost - close to 2-2.5X. 2. You can get even before perf ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. D3DXCreateEffectFromFile() problem

  Hi people. I'm having a problem using effects. Of the 15 or so fx files in the samples, only 2 will successfully go through with my code. It doesn't really make any sense :( I do know that those that fail will cause effect to be null in the following code. Note that this code is from a wrapper and each new effect will be in its own object that initializes using the code: DX9Effect::DX9Effect(char* filename, int uid) { D3DXMatrixIdentity(&matrix_world); D3DXMatrixIdentity(&matrix_view); D3DXMatrixIdentity(&matrix_proj); strcpy_s(DX9Effect::filename, filename); char newpath[MAX_PATH] = "effects\\"; if(std::strlen(DX9Effect::filename) + std::strlen(newpath) < MAX_PATH) strcat_s(newpath, filen ...Show All

• Visual C# local or remote path

  Hi, how can I determine (inC#) if a path refers to a folder/file on the local machine or on another machine in the network Thanks for your help, Ralph Hi, Simply by checking the file path starting characters you can find that if its starts with "\\" then its network drive and if its not starts with "\\" then it would be local drive (Except the case of Mapped drive so if you are not using mapped drive ). If you can't use this because of mapped drive will give you the wrong result, then inform me, HTH, ...Show All

• Visual Studio 2008 (Pre-release) Image formats for toolbars?

  I'm curious what people are using for images on WPF toolbars Are you using icons, bitmaps, a geometry in XAML, or It's nice that you can easily make an interface scalable with WPF, but that implies that some sort of vector images would be best. But how do you make those look good when sized down to small areas like 16x16 I'd like to hear from some developers/designers that have been working with this awhile on what's worked best for them What gives you the best tradeoffs between ease of creation, good looks at larger sizes, and good looks at smaller sizes That's a good point I hadn't thought of before. That by using icons in XAML format, you have options to animate that you wouldn't have with a bitmap format. That in itself may be ...Show All

• Visual Studio Team System Cannot create database project for SQL Server 2005

  I'm not sure why it's trying to make an initial connection when I try to create a project but it is telling me it cannot make a connection to SQL Server.  I have a named instance installed and don't know how to tell VS where the instance is residing.  I go to File -> New -> Project then under Database Projects -> MS SQL Server I click SQL Server 2005... I'm assuming I'm missing something very basic.....
