• Visual Basic Runtime controls (controling textbox)

  Hi, I have a question about controling textboxes created runtime. Is there any way of accessing directly to particular textbox created runtime (ex. textbox3) now i'm going trough all controls on panel (textbox is on it) and searching for particular control name. That way i get contorl index. code i'm using for creating them: While items < i index = New TextBox With index .Name = "index" & (items + 1).ToString .Font = New System.Drawing.Font("Arial", 8.25!, System.Drawing.FontStyle.Regular, System.Drawing.GraphicsUnit.Point, CType(238, Byte)) .ReadOnly = False .Size = New ...Show All

• .NET Development Data Encryption

  Hello all;   I want to encrypt a string for example a password and then save it into database(SQL Server). And also when I retrieve encrypted data from database, I should be able to decrypt it. Is there any way can I do that   Simple code snippet would be truly appreciated. Thanks for your time spending.

Don't ever create your own algorithm, they will never be as good as the ones that have already been developed. If you are using .NET 2.0, there is a ...Show All

• Windows Search Technologies Problems searching with German IMEs

  I have found that when using a German language keyboard, I sometimes receive no search results for terms that yield several results if the keyboard language is U.S. English, or anything else for that matter. For example, a search for the term "ipass" yields 623 results on my machine with English as the keyboard, but 0 results when the keyboard is switched to German (Germany). A search for "ipas" returns the expected set of results. I have tried the latest version of WDS Enterprise, and also the current 2.6.5 beta. With the current release version, the term "telekonferenz" would return no results, but "te ...Show All

• Software Development for Windows Vista How can an activity close itself?

  This might be a little bit of a naive question. I want to have an activity terminate itself after some activity-determined event. As an example, I tried just using a timer (the real code will be looking for other events besides time). I created the following code (as part of an activity) and can’t figure out how to finish up in the MyTimer_Elapsed. I know my example is wrong and can’t work… the ActivityExecutionContext can’t be saved and used later, but I think using it incorrectly shows better what I’m trying to achieve.   Timer MyTimer = null ; ActivityExecutionContext MyContext;   protected override S ...Show All

• Visual Studio Visual Studio Debugger Crashes after Exception Thrown

  While in debug mode in a particular ASP project, Visual Studio will hang after any exception is thrown. This happens if the error is handled or not handled. The above stated problem won’t occur on a new ASP project. The problem project has approx 40 aspx files. Business classes are maintained in a separate class project. To shut down VS I need to “End Process” from Task Manager. Note: VS is usually using 85%+ CPU at that point. The project will even hang when I throw an error. t hrow new Exception(“dang”); The Exception window pops up with the correct error but I can't close it ...Show All

• SQL Server Using Custom Classes

  Hi ! Currently we have over 500 reports working with reportserver. We're planning to add on our report hyperlink to some pages of our web application. What i want is to have a classe with a function that will return a string for the action to do on the "Jump to URL" function. The reason why i need to use a classe is because if we change the name of a page we dont want to modify all the report one by one. Also we have some client that prefer to not have link in their report so i want to be able to disable this quickly. This function will allow me to do all that. So using Visual studio i've done a classe and i've put the .d ...Show All

• Visual C# Is C# the best language to learn/know?

  Hello, I am currently studying C#.  I presumed that C# is much better than VB.NET and so started studying it.  But it seems to me that most everyone related to microsoft is always pushing for VB.NET and not having much to say about C#, so what is going on   Id Est; - I now regularly catch the Dot NET Rocks radio show, which seems to be based, or at least biased toward VB.NET.  - I stumbled upon the VB.NET PDC05 disk online at http://msdn.microsoft.com/vbasic/pdc05/default.aspx which I was quite impressed with, so I thought I'd find the C# equivalent, to no avail.  Please let me know if there is one availa ...Show All
