• Windows Forms Label with invisible background.

  I have a form with a label in it. I want to show the label, covering the whole form, with a number in it. The app is a multii screen image viewer, I'm trying to show which monitor is which. I've set the style to allow transparent background ( I'm interested to know what genius came up with that idea ), I've set the deprecated 'DrawTransparent' property, I've set the background color to Color.Transparent, but no matter what I do, including downloading several controls on the web for transparent labels, I cannot get a label that doesn't erase it's own background to the color of a general dialog box. Does anyone have any suggestions Thanks It works fine for me, but not with a ComboBox, which appears to redraw its text area over the ...Show All

• Windows Forms design time

  Hi. I'm trying to skin an application and to make things easyer i want to ba able to assgin an image for each part (area) of a control in the designer. A certain control has up to 15 different areas and for each area i need 3 images (normal, MouseOver, MouseDown). One approach would be to have 15 ImageList properties for that control with an appropriate name so that it is clear which area the images are for. Another approach (which I consider a better one) would be to have one property of type System.Collection.Generic.Dictionary<TKey, TValue>, where I could set the TKey value to be of some enumeration type, which determines the area of the control and the type of image. e.g: public enum ImagePosition { area1_Normal, a ...Show All

• SQL Server Where to use SQLCLR ? Data access is not recommended?

  Just wondering which scenarios is suitable to use SQLCLR. Any kind of data access is not recommended I guess. Only things that cannot be easily done in TSQL should be done in SQLCLR but why Can't those things be done in app layer itself Scenarios recommended for SQL CLR: - External data access like filesystem, registry etc - Complex calculation - Recursion without data access (this can be implemented with CTE for data access) If data access with SQL CLR is not recommended why should CLR should be even used and logic reside in database layer.. it makes no sense to me. Any thoughts Hi HiTech2k, When you use SQLCLR to do data access, do you do the manipulation in .NET DataTables If so, isn't it slower than ...Show All

• .NET Development Fixed Length Text File

  In c# VC 2005 - How do I read in a fixed length text file - keeping the fields in an array Sample format "A 2222222 2007/01/01 5.55 " StreamReader sr = new StreamReader(filePathHere); string line = sr.ReadLine(); string[] words = sr.Split(' '); // or string[] words = sr.Split('\t'); sr.Close(); For this to work fine you need to have right Delimeter. Otherwise you'll not get the right results. If you need to read all lines then you need a Loop on sr.ReadLine() like while((string line = sr.ReadLine()) != null) { } I hope this will help.

• Visual Studio VS 2003 SP1 install error

  Hi, My repeated tries of installing the VS 2003 SP1 fail because the installer can't find the "vs_setup.msi" file. This file is not on any of my Microsoft Visual Studio .NET 2003 Enterprise Architect " CDs. (3 CDs total). I've tried looking on my computer's hard disk also and "vs_setup.msi" is not there either.

• Visual C# Unable to load dll HRESULT: 0x8007007E

  I have moved a C# project from Visual Studio 2003 to Visual Studio 2005 Express. I get the "unable to load dll HRESULT 0x8007007E" error when making a call to an unmanaged dll. This previously worked OK before. I have tried putting the dll into the bin\debug directory, the windows and system32 directories with no success. I have also added the debug directory to the environment path variable but still no success. I have investigated trying to put a dependancy in the project on the dll but can't find a method of achieving this. I have also tried running the application and the dll outside of the IDE in the same directory and it still can't find the dll. Is there a difference in the way Framework 2.0 loads unmange ...Show All

• Visual Studio Missing key

  Hi everybody I've just wrote an interface and commented it well. Than, I derived some classes from that interface. All I want to do now is: How can I reference to the interface documentation within my single class comments. I really don't like to copy'n'paste the interface comments to my class documentations. My classes are supposed to do what the interface dictates. So extra comments aren't necessary. Is there a reasonable way to let insert the comments automatically. I tried something like this: /// <summary cref="IMammal" /> public class Deer : IMammal { ... } The result with Sandcastle is: [Missing <summary> documentation for T:animalpark.Deer] Does anybody know a good solution or workaround Thank you very ...Show All

• Visual C++ Using C++/CLI to develop web apps

  Is it possible to develop web applications using VC++ (C++/CLI) in Visual Studio 2005 Standard/Professional Editions I would guess that the answer is 'yes', but I would like to confirm. I checked out the Web Developer Express Edition, but it only includes VC#/VB. I am looking for a way to develop web apps using VC++ (C++/CLI). Thanks, Kumar Initially, it is going to be a fairly simple application: Sort of a calculator, where users would enter certain parameters and then click a button to get an answer. There may be a need for accessing a database. The second application will be a more complicated modeling/analysis engine where users would input quite a lot of information and run some complicated ...Show All
