One of my forms has a few textboxes that are required. If I try to use an if/then statement, the form shows a message box stating the error but then continues and eventually crashes because the textbox wasn't filled out. How to I make the program stop what it's doing if the box isn't filled out?

I am making a process monitoring program for his game server. Occasionally, the programs stop responding. I've used the if process.responding then process.kill la de da, but its not working right. Is there a debugging tool out there i could use to intentionally make a program stop responding?

Is it possible to make a program intercept and stop certain write requests? I need it to stop viruses from tampering with an antivirus database. If you can, how do you do it? If not, is there another way to stop viruses from changing the database?
View 39 RepliesI want to make a program that will (by timeing) click continuously until I press the stop button or a key like f12. The only problem is I have no idea and got only how to click from other posts of same concept. This is what I have.[code]Now I want a timer to help it click every 1 2 or 3 seconds, whatever it may be in the text box.
View 2 RepliesOut of curiosity, is there a way i can make a program stop or pause for a period of time (which i would choose) before continuing the code WITHOUT a timer.I think I've seen this done before, but I'm not positive.Also note that I'm talking about a forms application (not a console app if that would be any different.)
View 3 RepliesI have a RadioButtonList control which triggers a Sub LegalGaps on SelectedItemChanged event. This Sub creates and fills in an array the size of which depends on the User's choice of radiobutton options. The second Sub AvailableDays shall be able to read that array and highlight the days in the Calendar control accordingly on DayRender event. May I somehow declare an internally created variable a public one?

View 2 RepliesI created a form and have the variable inputs for 4 motor run statements. Then with a start button the script starts and it is surrounded by a for next statement to loop 10 times. It works fine but if i need to stop the execution of the script with a stop button. I put the stop in a new section but of course does not work to do a motor stop. It just causes the exe to not respond till the loop is complete. Just need to be able to stop the Run1_Click button section.
Edit:I do not mind if it finishes the 4 motor run commands and then stops execution of the loop. So need to figure out a way to trigger a stop from a button on the form to stop the cycle. For the future the loop will be a variable integer input so 10 will not be the standard.
Edit::Does a ' Do ' statement sound like the thing to use? If so how and where would I place that? Have a Stop button on the form and it would stop after the 4th motor run command.

okay so i was thinking of making a program that can take a text file filled with code so the text file would look like this

and have the program display
Title
Text = blah blah
text = blah blah

If it is at all possible, I would like to print a page that is layed out with labels filled with text from previousley stored information from the program. now, obviousley, because the text can change in amount, and so the labels need to be able to change in size, and if at all possible allow multiple lines, though if there is no way to do it, then an unchagable text box would serfice.
There is a problem though, the fact that the labels will be changing size means that the position of the labels needs to be variable to the previouse. Example: the box above needs to be bigger, so the box bellow needs to drop down equall to the amount that the above grows.
I 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"?

View 8 Repliesi just recently started programming VB.net 2010, My background is PHP so programming is what i want to do.I have a program im making, kinda a project for myself.I have got alot of the design elements made, but im stuck on some of the items that i would like created.
1. I have Combo boxes, the names of them are "wowlocation", "wowreagon". these all have default values. How would i go into the registry get the values and if i change it it would auto put it into the registry.
2. I have a file in foulder named "realmd.***" when i choose my options from the boxes it must put what i selected into the file (The file is a normal txt file with the ext *** only), it has to pull the "wowlocation" and "wowreagon" from the DB, when it does that it is able to pick the right thing to put on,There is only 3 Values, US, EU and WTN, each will have its own text to put into the file, how would i Open that Specific file and then write the values i choose?
3. How do i make a Image Launch a Program? (The location of the file is in the registery, basicly "wowlocation/wow.exe" ?
4. I have a Status Image, i have a spasific IP, I need to check if its responding, if not itll change a image to down.png and if its responding itll change the image to up.png, picturebox name "statusimg"?

1. When i inpute the month, it doesnt input it, it just makes the combobox on the website smaller for some reason
