When I end my app by pressing the stop button in visual studio, is there a way for that event to trigger some exit code? I'd rather do that than include a visually distracting quit button.
Better still would be to program some kind of key sequence, eg control + q to trigger some quit code so my app can exit cleanly. Is this possible? I wouldn't know how to program a key shortcut but it might be handy.
Well, I've read (and learned) that the finally block doesn't always execute its code (even apart from pulling the plug).FYI For more information, see try catch finally question

I wrote the following code to build a basic game that makes two cars race (randomgenerator) and let the user pick their bets on the end results. I've gone terribly wrong somewhere in that my cars only race halfway then get stuck behind the start line and the programme keeps repeating the beeping and the messsagebox.show and adding results to the 'incorrect' box.
The only way to terminate the application is to hit 'stop debugging'.

Option Strict On

This is a rather odd problem i am running into I currently have a web page that i am adding hyperlinks to that when clicked will open a file (usually Word file though there are some Excel files). Here's the problem. When debugging all of the files do open properly, however, files labeled .doc, .docx, or .xls all end up stopping debug mode when they open. I have .docm files that open properly and do not stop debugging. There isn't an error thrown anywhere just a forced stop of debug mode it seems.
Has anyone ran into a problem similar to this? I have only tested locally but i am unsure if it will cause problems when putting it on the test server. I'm still not quite done with the rest of the page so i was hoping to stop this behavior before completeing the project.
When I go to Debug my program (F5), the program will load, until I click on the form with the main part of code in it, and then the program freezes, although it doesn't lock up because as soon as I press stop debugging/ task manager end process, it closes fine.
I will attach the zip of the program here. The form that it freezes on is "Black Ops". Edit Due to the forum not accepting my .Zip file (Invalid file type), I will upload it to MediaFire. Download link (445kb): Click Here
I have a small problem, When i Start Debugging my program a lot of windows popping up such as: Watch 1 - 4, Memory 1 - 4,Autos And Registers. What should I turn off to make them stop popping on debugging?
View 4 RepliesI have a START and STOP button and when the user clicks "start" the program does a whole bunch of calculations and all. However, I noticed that when I was testing the program I clicked STOP the program continues to execute stuff.
My START code is basically a while loop that iteratively does some calculations.
So I just put a boolean variable as the while condition and when user clicks stop its set to false and when user clicks start its set to true. However, when I click stop, the condition is set to false yes but it still executes all the code until the condition is re-evaluated right...so my question is how can I get out of the while loop when user instantly clicks "stop"?
I installed VS2008 ona newVista Ultimate 64 Bit machine. Works great. But if I try to change some VB2008 code while debugging, the system says, "Changes to 64 Bit applications are not allowed". Why is this? And will programming on a 64Bit machine always be hampered like this
View 4 RepliesOn my last machine I had created a way to see a GUID variable while debugging by hovering over it. I don't remember what it was (a visualizer?). I have a new 64 bit machine with vs2008 - is there anyway to mouseover a guid value and have it appear? What makes guid's so special that their value doesn't show like most variables?

View 1 RepliesPrior to VS 2010 I was able to debug VB6 client code from the .Net IDE by setting "Start External Program" to vb6.exe (full path), or attaching to the running vb6 executable via "Tools->Attach to Process" and have execution stop at the required breakpoints in my .Net code.
Now with VS 2010 I seem to be only able to accomplish the same by setting the target framework to 4.
Is this a bug in VS 2010, or is there a switch/option that controls this?
I am converting an old asp project to a new .NET project. Now, all vb code are inside aspx files, and we are on the process of moving all vb script from aspx files to .vb files. My problem is, I can't debug the vb script inside most of the aspx files. All my friends don't have this problem. I think the problem is with vb text editor.I am using Visual Studio 2008. Is there anyway, I can make visual studio understand that aspx files have vb script inside them.
View 2 RepliesI have some VB6 code that instantiates a class which handles events that are being raised from a VB.NET component. The VB6 is pretty straightforward:private m_eventHandler as new Collection
public sub InitSomething()
dim handler as EventHandler
set handler = new EventHandler
m_eventHandler.Add handler
m_engine.Start
[Code]...
My problem is that when I debug the VB6 program, the first time InitSomething gets called, the event will not be handled (the VB6 event handler is never entered). Subsequent calls to InitSomething does work.
Everything works as I would have expected when I run the program outside the debugger. At this point, I'm not even sure if this is something I should be worried about.It may or may not be relevant but the VB.NET was converted from a VB6 using the Visual Studio code conversion tool (and subsequently manually cleaned up).
When debugging a program and then we take it to a line breakpoint,then I want to modify the code again.but could not and such message appears in the image which I attach.What can we edit code program at the time of the process of debugging.This can be done in visual basic 6 ide?

There has to be a setting for this somewhere, but for the life of me I can't find it. When I "Start Debugging (F5)", if there is an issue with my code, I get a "Build Failed" notification, in the lower left of my screen. I would like to be directed to the location of the failure. So far I have been lucky and have been able to find the offending code but this is getting scary .

When I run or debug the code, it asks for the First Number and then just completes the running of the program without asking for the second number and uses some random number. The console.readline() doesn't work either, the console window just disappears.
So im pulling data from a db and then counting all the data on that db but it counts before the data is pulled. Anyway to stop this?

View 2 RepliesI've seen on here how easy it is to disassemble code and wondered what levels of precautions people here have used or would use to make the process of hacking ones hard work.
All methods i have come up with are easily worked around. simply swapping the condition for a jump in assembly code would undo even password security.
Probably the most interesting idea i have come up with would need a c module in the project that would write into memory part of the routine on the fly (i.e. it writes the conditional jumps into memory using pointers but again all that is needed is to remove the c block and write the correct code into the exe file.
The only way i have seen is to create 2 passwords one for the application and a secondary one which is stored on a server so the software checks against a serial number database, this also is limited as unmodded it cannot detect if the user is legitimate, only that there is one person using a specific password at a particular time, and in any event it is still a case of changing the conditional jumps so it works when it is the wrong password or doesn't contact the site in the first place (or another site with a valid password and allows multiple users on its database)
whenever I have to convert something to a value (for example,lets say I have to convert something to
a boolean) visual studios will give you their advice of CBool, which works, but that's VB6 and I do
not want that. If you know of a plugin that does it, I'm open to that as well.
How can I completely stop code execution?
Also, how can I hide a form and keep all information saved so I can bring it back up again?
For instance, I have form1 with "alpha" written in a textbox. Now when I hide form1 (Me.Hide), I would like to be able to bring form1 back with "alpha" still written in the textbox.
Currently, I hide it, and when I show it again, the textbox is empty.
how to stop the application from doing the code on next line immediately when the user enters nothing in the textbox and pressed a button?
