Is it possible to have radio buttion 1 control this code and have radio button 2 control the same code with different sizes? If this can be done it will get me buy until I learn a better way. It is a small envelope app, someday I will add a database to it too hold all my address. Right now I only use a couple different sizes.

I am a sys admin for a company and our programmer left several months ago. a program they wrote is now failing and i am struggling to work out why. the program basically pulls data from a csv file into a readable form, written in visual basic. the application works on a couple of machines but not on a couple of others. i have matched up .Net framework versions, MS Primary Interop Assembly versions, still no joy. As the app works on some pc's i am wondering what other differences could cause this?
The error output is:
see the end of this message for details on invoking just-in-time (JIT) debugging instead of this dialog box.

CODE:
JIT Debugging
To enable just-in-time (JIT) debugging, the .config file for this application or computer (machine.config) must have the jitDebugging value set in the system.windows.forms section. The application must also be compiled with debugging enabled.
For example:

When JIT debugging is enabled, any unhandled exception will be sent to the JIT debugger registered on the computer rather than be handled by this dialog box.
i want to random 3 variables...
dim a as integer = 1
dim b as integer = 2
dim c as integer = 3
dim result as integer
result = random ( a , b , c)
How do i write the random stuff in visual basic.and how would i write something that Deletes the a from the random ( ); so im only left with random ( b , c ).
For example I have a form that have 2 Label Boxes both have values inside. lets say that the first Label box value is:
5┌─┐ this button adds value of 1 to the first label box (5)
the second label box value is:
2
┌─┐ this button adds value of 1 to the 2nd label box (2)
in here I have a label box to display Total: 7 so when i click each button, I would like that Total label box calculates Total of Label Box 1+2
I`m trying to figure out how to use a timer to do something for a couple of seconds. Let`s say i want to prompt a message for 5 sec and after to disappear it.Or On a button`s click to appear an image and after 3 sec to disappear it. How i`m i going to do it?
View 8 Replieswhen the form loads, there is a table and i use code to set the row count to a variable from a previous page. this works fine. the problem i am having is that i cant get the row height sizes to be evenly spaced, there is 1 huge row then heaps of tiny ones
View 4 RepliesI have a class SELF that is hosted by a couple different classes. Basically, the hosting class HOST calls a method in SELF. SELF is passed HOST as an argument in the constructor, so SELF can call methods in HOST. In normal situations, a call to HOST will do something minor, then return so that SELF can continue. However, for one particular type of HOST, one of the calls from SELF to HOST will cause HOST to call SELF, and so on ad infinitum. A classic, though convoluted, case of recursion. Once again, this is only going to happen for one type of HOST. For other types of HOST, that particular call will not cause HOST to call SELF, so there will be no recursion. Nonetheless, there is no getting around it in one case.
I can see two means to decouple the recursion, and I am wondering which one (or a third) would work best:
1) Add a timer into that particular HOST so that the call from SELF that would trigger the recursion would actually just start the timer in HOST, then return. When the timer ticks, HOST can call SELF. The recursion is broken because the call to SELF is done on the timer event, and not when SELF called HOST.
2) As it happens, HOST makes the first call to SELF in a background thread, which means I don't really need to worry whether this thread blocks or not. Therefore, I could have this background thread spawn a second background thread to make the call to SELF, then have the initial HOST thread JOIN on the second thread. This means that the initial thread will block until the second thread finishes. Meanwhile, the second thread will call HOST, and the HOST won't call back to SELF, it will just return like all the other HOST objects would do. This will allow the second thread to run to completion. When the second thread completes, the first thread will take over and call SELF again on a new second thread. Therefore, the recursion is broken because the secondary thread will always run to completion, and the primary thread will wait for the secondary thread to complete, then call it again.
I tend to prefer the second option, because the first option involves a pause of some length (the minimum for a timer, which is pretty small), while the second doesn't, but the first option is actually a little easier to implement.
I have a filesystemwatcher that watches a couple of folders! The files coming to the watched folder are coming from a server. And for some reason the created event is not raised..If i move the files for a sec from the watched folder to a another folder and then copy them back to the watched folder it all works fine! Strange.So if the created event is raised from the same computer that the service is installed on it works great, but not if the files are coming from another computer.

Very new to web development and had some session issues a couple of days ago. I have those now resolved but having trouble telling the page to redirect home after the session expires.
Using the example from my previous post:[URL].. I have this set in areas of my main page in order to redirect if the session has ended.
If Session("UserClassInstance") Is Nothing Then Response.Redirect("Login.aspx")End If During the testing; after Session_End fires, I go to the control that contains the above statement but seems to think that the session not nothing and will not redirect.
I have written a VB .NET 2010 application which displays a "you have new mail" window/form with an OK button that closes the form.
Some users have received new PCs with dual-monitors and the OK button is no longer visible on the form - it's at the bottom but off-form.I guess that this is related to a different screen resolution and not the dual-monitor setup itself.how to make my forms auto-resize? I though this was automatic in VS 2010.

View 4 RepliesIn fact, the process is being written into a library to be pulled in from other applications. However, how do I provide a way for a WinForm to subscribe to the process to update as the process gets executed? I've open this question from both VBA/VB6 and .Net because its part of the gamut for UI development.It's also worth mentioning that these are subroutines and not classes that are running the methods, so event raising appears to be out of the question.[code]
View 1 RepliesWhen I downloaded VB 2005 Express I took advantage of the bundle of goodies on offer and downloaded SkinCrafter Light.I really like the four skins that come with SkinCrafter Light, and I am using one on my current project (example of the skin I am using here). However, SkinCrafter Light has a couple of bugs with RichTextBoxes (these bugs are known to SkinCrafter, as I can see posts about them in their forum, but they have gone unanswered in over two years!)One bug is that any text that is colored in a RichTextBox is turned back to black when the skin is applied, and if you click anywhere in the RTB the application will crash (you can see my RTB on the right bottom of the form in my screenshot above).
I use colored text in my RTB, but, at a pinch,I could make do without (as I really DO like the Skin), but the problem remains of crashing when clicking inside a RTB.I was wondering (can't test at the moment as I am at work) if simply placing a control, such as a Button, Label, Picture box etc, set to transparent, over the top of the RTB, would solve the problem, so a user could not click inside the RTB (but would be clicking on the invisible control over the top instead).

View 3 RepliesI have a slightly unusual application that is optimally designed by doing the following. We have an application that references a number of graphic sets for unique artwork utilization. The application is in HD and the graphic sets are a bit large about 20 megs per set. We have found that the optimal design for this particular application is to create a unique .Resources file per set, compile this .Resources file into a .Dll file using Assembly Linker (AL.exe) and reference the .Dll via the application and load the graphics upon demand or selection actually of this unique set within the application.
Question is this as I have been unable to find any data on this aspect.
Is there a limitation on the number and size of .Dlls that a VB .Net application can reference?
Specifically, we will likely have 20-25 unique graphic sets reesulting in 20-25 unique .Dll files of about 20 megs per .Dll. On our deployment boxes for the applications, we have 2 GIGs of RAM so no issue there.
Just curious if anyone knows if I am breathing down the neck of an inherit limitation within VB .Net 2010 by creating the above monster.
I have a custom class. I would like to add an event that triggers when the form it is on resizes. Is there a way to do this?

View 6 RepliesI have a basic VB.net app that displays a picture box with some text. nothing special. looks fine on my computer. If I display it on someone else's computer with a larger font size (125%?) my picturebox and text looks off and stupid.
How do people account for this? Should I simply get the new font size and multiple all positions, lengths and widths of object by 1.25?
I'd obviously like my dialog to scale properly and look as expected in any display no matter what font size is selected.

View 2 RepliesI have less than good eyesight now as my age increases :) I have managed to make most text areas/dialogs etc suitable for my eyesight, but can't find any way to edit/alter the Toolbar Icons - I expected to fin (at least) a seting for 'large' icons, or a way to increase/decrease the sizes - but so far I haven't been successful.
I find the icons/toolbars to be poorly designed in that they are on a grey background which just serves to minimise their effect.
