• Visual Studio Express Editions Hash Table Question

  Hi, what I need is as follow. I have a class that contains a string. ref class WordObj { public: String^ string; Int32 info; // further data }; Now I want to add such WordObj to a hashtable. myHT.add(wo->string, wo); As you can see, the string inside the WordObj is the key. Is it possible to prevent the hashtable object to store the string twice Once as key and a second time as part of the stored object. It is important, that the string stays part of the object. Thank you, Bernd String class in .NET is immutable. It means that it can not be modified. You can not change t ...Show All

• Visual Basic Problem in image compression

  I'm trying to compress an image and all my code looks correct, but I'm not sure it's 100% correct. My understanding was that compressing an image would reduce the quality.. Is that not correct My code does decrease the size of the image, but even when 100% compression is selected there is no change in quality. [code] Private Sub TrackBar1_Scroll(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TrackBar1.Scroll compression_rate = TrackBar1.Value * 100 Dim qualityParam As New Imaging.EncoderParameter(Imaging.Encoder.Quality, compression_rate) Dim jpegCodec As Imaging.ImageCodecInfo = GetEncoderInfo("JPEG&q ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. MDX (Dec 2005) Working with D3DX

  I just upgraded to the latest and greatest DX SDK, mainly because I really wanted be able to use the Direct3D.Font.MeasureString method (although I'm a bit confused as to the parameters it takes, but I should probably ask that question in another thread). Anyway, I added a reference to the Microsoft.DirectX assembly labelled with the version 2.0.0.0 and runtime 2.0.50727. Now I can't seem to find where the TextureLoader class has gone to. It seems the Microsoft.DirectX assembly doesn't include the Direct3DX namespace, which was where it was in the older version I had. According to the docs, TextureLoader is now a member of the Microsoft.D ...Show All

• Visual C++ Porting-to-Unicode Issues

  Hello, I recently installed Visual Studio .NET 2005 Beta 2, and was very quickly very pleased with the IDE. As a step to test the new IDE, I import an old project I did, including a String class I developed. When I tried to build however (with Unicode enabled, as it is by default), I got about 70 errors from various header files, such as atlbase.h, atlconv.h, and statreg.h .  When turn off Unicode support, all the errors disappear, and all problems go away. Has anyone else seen this, and possibly know what can be done about it Thanks, -Chris Yes, that is largely what is happening. One is used by the s ...Show All

  I have a parent user control. I want to capture all mouse clicks within the control, even if the mouse click is on a control within my parent control. How do I do this You can try and look for WM_PARENTNOTIFY and WM_MOUSEACTIVATE event. What I suggest you do is,create a WinForms Application and then change the property of the project to Console App,so that you can see the Console Window. In your user control, protected override void WndProc( ref Message m) { Console .WriteLine(m); base .WndProc( ref m); } you will see all the messages coming up in the Console.When ...Show All

  Hi I have a Generic SortedList of my class Product, with a unique identifier as the key. Each product has an itemcode property which may not be unique for each product (this is essentially just a part of the Key field). I would like to be able to search the SortedList and retrieve the index of the first matching product. I have implemented IComparable on the Product class however I am always getting -1 returned when using the IndexOfValue method - what am I doing wrong here Also, will this method of retrieval be efficient if there are a large number of products in the sortedlist, say 10,000 I will also need to be able to do a wildcard sear ...Show All
