• Jing-ta Running EXE without Framework

  So i made a program for this website. But i don't want the users to have to go threw the hassle of having to download .NET Framework just to run it. (Some use this program on Work Computers where they have restrictions on what can be installed) I am using Visual Basic 2005 Express and would like to know how to build to program to include all files needed to run so the other DO NOT have to install .NET Framework. Hi, The .NET Framework is essentially required to be installed on the machine where your .NET Application would be physically executing.

• Fawadb map string value to a variable name dynamically?

  Hi, I'll use a really simple example to describe what I want to do. Say I have a Class Person, with members being Name, Height, Age, Sex. I want to be able to call a function say person.NextValue, and it will return the value of one of the member variables. So if it is called the first time, it will return the value assigned to Name. The second time the value assigned to Height and etc... Any ideas on how to do this I have had a crack at it and have done the following. In my class I have created an arraylist containing the names of each member as a string. When .NextValue is called it steps to the next string in my arraylist and returns the Name of the member. For my approach to work what I need to do now is return the Value associa ...Show All

• RBecker Custom Control wont ctrl-c copy.

  Hi! I made a nice toobar/database navagator. using a custom control with a hidden navagation bar in it. its got a slider and some buttons like print and post.

• carrielm VB: Edit & Continue

  I have searched all over the net for answers to this problem but have not yet managed to find the answer. I have a couple of vb projects which I have recently converted from VS2002 to vs2005 Prof. One project that I converted a number of weeks ago does not allow edit & continue now, whereas the most recent project conversion does allow edit and continue, both in the same IDE with same 'Tools/Options/Debugging/Edit and Continue' settings. Does anybody know of a configuation element that can be added/removed within a project that might control this behaviour, or otherwise offer a solution to this problem Many thanks in advance.
