• Visual Studio Express Editions Problem with VB source code/original

  I was baffled by some code that didn't work when it looked correct. I inserted a breakpoint, and it was never reached. I noticed the breakpoint icon change into a "yellow ring" with a message that my breakpoint can never be reached because my "source code is different from the original version." This seems to be caused by an attempt to change code whilst debugging. I never do this. I searched for help and found that this problem can be corrected in the full version of VS - but I have Express and the options mentioned are not available. I also read that by deleting files from Bin and Obj, the problem could be fixed. Didn't work either. Luckily, I had a copy of the project from a few hours earlier. This ...Show All

• .NET Development get all form names.. and their tags please

  I itterate through all the forms of my solution like so: Assembly asm = Assembly .GetExecutingAssembly(); ArrayList allForms = new ArrayList (); foreach ( Type t in asm.GetTypes()) { if (t.BaseType == typeof ( Form )) { allForms.Add(t.Name); } } Anyone have any idea how I would then get the Tag property for each of these Forms that are places in the allForms ArrayList Thanks. You can’t... at least not without having an instance of those forums. Remember that reflection like what you are doing only involves examining type information, not examining an actual instantiated object and without an instance there is virtually nothing read ahead of time.

• Windows Forms Best Practices Disposing under inherited controls

  Dear Sirs: Two quick questions: 1) I have a MyLabel: Control, that creates a different Font to use as default, the constructor looks like: public MyLabel() { mFont= new Font(...); Font = mFont; } Question: should I override Dispose(bool) from Control and call mFont.Dispose() Or that will be taken care of by Control 2) To speed things up, I cache a LinearGradientBrush (mBrush), and create a new one when ReSizing, instead of doing so in OnPaint. Should I call if (mBrush !=null) mBrush.Dispose() before mBrush = new LinearGradientBrush(...); whenever I have to recreate the brush Thanks Daniel (a newbie at Disposing matters) If a class instance runs out of focus then the dispose method will (eventually) ...Show All

• Visual Basic Calling an exe multiple times

  I have to develop an application where I need to generate PDF from HTML. I am using ABCPdf component for the same. Now I am giving my users a web interface where they can select the HTML documents (lets say HTML1.html,HTML2.html,HTML3.html ...so on) and then the PDF gets created by invoking an exe which does all the work in the background. Now i want a scalable and robust solution to accomplish this task as my users can be any number and there can be n numbers of html documents to be converted to pdf. For example my user1 schedules 20 HTML files to convert to PDF like wise my user2 also schedules his 20 html files to be converted to PDF and there is no limit to the number of users. and so on .. so if I develop an exe to do the task ...Show All

• SQL Server ActiveX Script Task/Function Not Found

  We have a SQL Server 2005 Cluster that we are trying to send email from to notify when certain jobs have completed, failed, etc. We are having a bit of a problem getting the email to work and I believe that the failure is at the SMTP server, not at the SQL level. That being said, I'm trying to create a simple SSIS package that I can use to test connectivity to the SMTP server with and send email. I've added an ActiveX Script Task that calls a COM object that actually sends the email. I keep getting a "Function not found." error when I try to execute the package, and I have no idea why I'm getting that. It says that the errors were found during validation. Can anyone help Function not found ...Show All

• Visual C# Code convention

  Hello, As a development team leader I have a difficulty to exlpain logically the following case: We write code in c#, designing classes that will hold data(stored in SQL DB). Let's say for example a class which will hold the DB user information. The DB table will hold the followin columns: [UserID],[UserFirstName],[UserLastName],etc... Now the class will hold the following properties: UserId,FirstName,LastName. The question is why using "UserId"(as the property name) and not just "ID" like any other native objects in the .net framework Thanks, Itzik Paz. UserId is more descriptive of what the field actually is.  Id is short for Identifier, and could be an identif ...Show All
