I have a piece of code that would be greatly reduced if a variable can be used instead of the actual method. (I am using a structure) kinda like the difference between the following code.
srrMulti.mthChildProp1.varRecall = strVarRecall
subPageRef
srrMulti.mthChildProp2.varRecall = strVarRecall

View 3 RepliesI have nine pictures that I need to animate -I need to use the ToString method and a counter to concatenate a file name into a string variable from the Image.FromFile method. Once the counter reaches its maximum value, and the last picture is displayed, the counter should be reset to zero or one depending on how the first image file has been name. Also a static counter variable should be incremented in the time routine. what I have so far -- I know what I have to do; however, I just do not know how to code this properly.. Right now I have this going thru a button procedure but it needs to go through a timer.

I'm looking for a way to search a string variable for two words and copy the text in between them into another variable. This needs to be done as many times as the match occurs.
View 3 RepliesI'm trying to complete a time program for a class that I am currently taking in which it's supposed to utilize a Tick Method. Essentially, the Tick should be incrementing the time by one second. The problem is that I don't know where to place it. The book I have doesn't go much into this, just the code. I have also placed the timer in the Designer, set enable to True and set the interval to 1000 milliseconds. This is the code I found for the Tick Method

I am trying to execute a command that works with hard coded variables, but when I try and replace the name test below with selectedname, I cannot get the syntax for escaping the command. The basic idea is I am using WMI to query the app pool names and then selecting one and storing in the slectedname variable, which works when I test with a msgbox(selectedname) line. It also shows up when I am stepping through, but does not get passed to the bottom command. The function where I am trying to execute the command is

When I've used the remove handler method in my code, I get this warning:The 'AddressOf' expression has no effect in this context because the method argument to 'AddressOf' requires a relaxed conversion to the delegate type of the event. Assign the 'AddressOf' expression to a variable, and use the variable to add or remove the method as the handler.Why do I have to assign the "AddressOf" expression to a variable?
View 6 RepliesI using VB.NET (VS 2008). I want to know if I can call a sub whereby the name of sub is in a varialbe.

Sometimes to make a variable/method/class name descriptive I need to make it longer. But I don't want to, I'd like to have short names that are easy to read. So I thought of a special addin to IDE like Visual Studio to be able to write short names for class, method, field but be able to attach long names. If you need to - you can make it all long or you can make single name long. If you want to reduce it - use reduction, like two views of the same code. I`d like to know what others thinking about it? Do you think it is usefull? Would anybody use the kind of addin?

I have 2 question, hope somebody give me an explanation: 1. Should a local variable call dispose method and set to nothing? 2.

View 2 RepliesLike I imagine everyone, I often have problems navigating my code because the flow can jump from place to place. For example, if my code calls routine1, and I then want to go to routine1's code, I know that I can click in the dropdown menu and it will take me to that sub. But wouldn't it be easier if I could somehow right click on the call to routine way and select something like 'take me there' which would transport me from the function making the call to the code for the function being called? Then it would be easy to hop from place to place.
