• ronnycopeh Reverse Engineering

  I have recently taken over for a programmer who has left for medical reasons. He has left a program with a few bugs and the code is nowwhere to be found. Is there a way to retrieve the code from the .exe using VB 2005, which was what it was originaly written in.. thanks Reflector is great for looking at individual methods. It will take significant work to pull out an entire solution using Reflector. Another option would be to dis-assemble the solution using ILDASM, modify the IL and re-assemble with ILASM, but that requires coding in IL rather than VB. In short, yes, it is possible, but not an insignificant undertaking. Jim Wooley http://devauthority.com/blogs/jwooley Hi, Y ...Show All

• hey_ian Numbers and date format in Visual Studio Reports (.rdlc)

  I am using an english version of visual studio 2005. I am from a spanish spoken country (CHILE!). Until now when I program, I can change the format of numbers and dates to the formats use in my country. The problem is that I need to format numbers in the reports that I create in visual studio. The reports are in the format .rdlc. I need that the numbers have as a decimal separator a comma (,) and as a number separator of thousands a period (.). In the case of date format, instead of showing the report the day "Monday, 12 of Febrary", I need to appear the name "Lunes 12 de febrero". How can I do this in my reports since I have a english version of the program Thanks in advance Mike ...Show All

• PN247 Receiving strings from Serial Port

The application give the impression that it is just hanging, untill I stop the application. Also how does the Read ...Show All

• Vijay_kar Stop application from terminating on form close

  I am working on an application with a notify icon. I want the application to continue to run even if the user closes the form. Is there any way to make this work Ken, Is there any functional difference between using Opacity and Hide Or Visible = False I was wondering if there is a reason to choose one method over the other.  I haven't tested this with a notify icon but t his should do it: Private Sub Form2_FormClosing(ByVal sender As Object, ByVal e As System.Windows.Forms.FormClosingEventArgs) Handles Me.FormClosing If e.CloseReason = CloseReason.UserClosing Then Hide() e.Cancel = True End If End Sub Note that you want to check the CloseReason property so that your app will shut down properly i ...Show All

• Schwarzer Schmetterling Can I create wizards for my program?

  i was just wondering if I create wizards for my program like to accept input from user then process them and stuff. Yes, you can create a wizard for your program. A wizard is nothing more than a procedure (or series of procedures) that walks the user through accomplishing a task....think of a wizard as a mini application No built in controls, but this is a nice one: http://www.codeproject.com/vb/net/GNWizard.asp With that control you won't have to make multiple forms. i will try it out quite confident i can do it. but a question, then won't my program have alot of forms u said no wizard control for winforms does it mean if i use something else there is Also i w ...Show All

• TheViewMaster Conversion of Double to Single

  I've been fighting with this problem for the past couple days and finally narrowed the problem down to the following couple problems: (This is all in VS 2003 .NET 1.1) #1 I have a Generic procedure that has a ByVal parameter of a Single datatype. In one of my modules, I happen to be calling the procedure passing in a Double datatype variable that has a value of 152347.04. When I step into the procedure, the Single datatype parameter then has a value of 152347.047. I've tried type casting the Double to the Single datatype but still get the same results. I can't figure out why it's not converting over the Double to a Single type by adding some erroneous value to it. #2 Also in the same procedure, I was passing in an ArrayList object that was ...Show All

• Roberto Sartori Dynamic execution method (release/debug mode)

  I understand that a VB app may be compiled 2 ways (ie.,Release,Debug). Generally, we would like to use release version in production but there are times when I need to use the debug mode. I do not want to maintain two versions of exe. My application reads off data from a SQL Table so I'm thinking of leveraging that for an IF... Else statement. However, I need to know if it is possible to include the execution mode into the VB script rather than rely on the compile method. Is that possible Thanks. Hi Jade, Generally, a release version of an assembly has certain optimizations in it that make it not debuggable. Information is often optimized away that is necessary for stepping through (debugging) the ...Show All
