I was wondering how to forbid to the user to press the combination of Alt+F4? or atleast if user presses Alt then MsgBox("...") so that the combination ruins...?
View 3 RepliesI may be doing this wrong but I want to call a sub when the user presses enter on a textbox. The sub then shows a window in dialog mode. When I close that window, the computer makes a ding sound. Why is that? Is there a better way for detecting enter being presses on a textbox and not getting that ding?
If e.KeyChar = vbCr Then
LookupItem()
End If
I have an app that I'm using Form2 to display informaitonal messages without having the user to press the OK button. I DIM form2 as a new form as a global and then add a lable to it on the fly and then control it's appearance with a timer. This all works great providing the main form is being displayed however I can't make Form2 show up if the main form is minimized or hidden. I can get around this a bit by keeping the main form maximized but change it's Opacity to zero but once I do that I have no idea how to return the Opacity back to normal when I do want to see the form. Anyone have any ideas on how to make Form2 display if the main from is minimzed or how to control the Opacity of the main form so I can return things to normal? I was thinking that there might be something I could do with hovering over or clicking on the icon in the taskbar but I don't know what that event might be.

View 1 RepliesI have 2 methods with the same name, with diferente signatures.
Public Sub Method1(ByVal Parameter1 as String, ByVal Parameter2 as Boolean)
Public Sub Method1(ByVal Parameter1 as Integer, Optional ByVal Parameter2 as Boolean = False, Optional ByVal Parameter3 as Boolean = False)
If I call Method1("My String Parameter", False) it will not give and error, it will try to convert the parameter to integer and use the overload.
Is there a way to forbid the implicit conversion in this specific method or in this specific parameter. For instance, I changed the second method name, but its not an elegant solution.

View 3 RepliesI'm trying to work out with visual basic. I need to calculate the probability of having a certain sum when randomly choosing 5 of 36 possible numbers. I already know all of the 36 possible numbers, and I know what the total number of possibilities is, I just need to write some code that will list all of the possible sums for me when you add any five of those thirty six numbers together. Ideally I would be able to also have it count how many of a certain sum occurred, but even if I could just have them as a list and I just count the instances, that would be fine too.

I'm trying to produce every possible combination of the letters in a word, however I've been very unsuccessful at figuring this out.
I can't seem to grasp what I need to do to get this working, I've been at it for the last four hours or so.for example, the word "one" would produce: one, oen, eon, eno, noe, neo.
I want to create a random number with the combination of the text entered in textbox. Suppose the textbox contains bharani. So now the random number generation is the first 3 letters from textbox and the random number from 1 to 1000. So my output must be "bha876"
View 7 RepliesI'm working on a program and in it I need to store all combination's of the numbers 1,2,3,4. I would like each combination to be it's own array, and instead of creating 24 different arrays (there are 24 different combinations 1,2,3 and 4 can be arranged) I was wondering if it's possible to create a nested array like so:
[ [1,2,3,4], [1,2,4,3], [1,3,4,2], [1,3,2,4] .......]
That way, I'd be able to reference index 2 of the above array and have the array [1,3,4,2] returned.I looked into multidimensional arrays, but this would require me calling each index of the row and column.I also looked into making a Structure in which there was an array that could hold 4 numbers, but wasn't sure if going that method would be practical or not.
I am trying to allow a user to press enter in a text box to trigger a text change of an object...

2. When you press enter,

4. Originally the book will have the text "Start" on it

View 1 RepliesIs there a way to repeat two popup input boxes (in succession) until the user presses cancel?

Do

The input boxes continue to repeat but when I hit cancel nothing happens... I'm sure I'm missing something to tell it when I cancel to go back to the MainForm I just don't know what it is.....

i've created a hangman game (Fully working) but since you can only "play" with one phrase (10 letters) it gets boring fast. Basic the current game works by on form load i define the slots (10 string which each hold a letter) and give them there letter. then the user type in a text box and if the textbox = any of the slots then the lbl repasenting that slots changes its text from "_" to the letter.
Anyway what I would like the button to do is when the user presses the start button a random number is generated. The program then looks into a textfile and based on which number is generated it takes a certain line (10 characters per line in a phrase) , moves them into the slots and the game starts. Is that possible to code or it too complicated. The textfile will be in the applications folder (words.txt).
