I am using a text box to display a list of items in which I want to be for reading only. Is there any way that I can not allow user input into this text box? Right now I have the text changed set to show an error message, that works but the text entered before the message box appears, still shows.

View 6 RepliesAlright. I have a project I need to complete by 11:00 am today. I need a program that will allow a user to input a phrase into a text box. Another text box to input a letter. Then I need the program to count how many times, the letter appears in the phrase. I have everything set up. I know how to count how many characters are in the string, but not how many designated letters there is.

How do I get numbers typed into a text box to be feed into my code and then the code to be ran?Below is the code that I want the information from a text box to be fed into. With the (0, 50) being the numbers.I will have a form set up like this, A button labeled Generate. 3 Text boxes total, 2 of them side by side with one being low and one high. For example The user will input 5 in the low box at 100 in the high box. Hitting generate the numbers will then be inserted into code and the result being shown in the 3rd text box.

View 1 RepliesI am using the code from the following link. Basically I am using the built in functions in visual basic for encryption (Cryptography). Seeing as there is a lot of code for it, I posted a link to the code I am using.

I get what this is doing and how it is doing it...for the most part. My question is how do you let the user set the key to be used instead of it randomly generating one? One of the reasons I want this over the random key is that the user will be able to remember it easier and the key generated sometimes has weird characters in it that not everyone will no how to use. I have tried everything I can think of.
The encryption works good, all I am using it for is to encrypt/decrypt a text document. If this is not too good of an encryption, that does not matter as I am not using it to encrypt any highly sensitive information. All I need is a way to be able to allow the user to set the key, but every time I try to pass a string through the encryption() method instead of a generated key (in the generateKey() method) it will give me an error.
I have lines in my text file like this:
x y
x Y
x y
x y

x y

Lets say I have 20 lines like this. I want to change this lines according to user input. So user will input how many lines they want to change in terms of row and column. In my program
Row=TextBox5.Text column=TextBox6.text
User must enter initial value for x and y. Let say the initial value is
x=1 y=1.
Row=2 column=5..
Now my lines should look like this.
1 1
2 1
3 1
4 1
5 1
1 2
2 2
3 2
4 2
5 2
x y
x y
x y
x y
x y
x y
x y
x y
x y
x y
Since I enter row=2 only two set of lines is change other lines remain unchange. But in my coding all the lines is changing like this:
1 1
2 1
3 1
4 1
5 1
1 2
2 2
3 2
4 2
5 2
1 3
2 3
3 3
4 3
5 3
1 4
2 4
3 4
4 4
5 5
which is wrong.
This is my code
Dim lines() As String = IO.File.ReadAllLines("C:\wirematches.txt")
Dim xValue As Decimal = Val(TextBox1.Text)
Dim yValue As Decimal = Val(TextBox2.Text)
Dim altValue As Decimal = 2.54
Dim lineTracker As Integer = 0

This code working fine for changes the column. But i dont know where i should write the code for row.
I know there are work-arounds like using a Select Case, but in my situation, it would make things a lot easier... especially since I won't know exactly what will be entered. I can't force the user to use a combobox or anything like that either, because it is going to be unique code for every situation. If there is no way of doing this, I will figure something else out, but it will require a lot more work.

I'm familiar with Visual C# and the try/catch for that but I cannot seem to figure out how to do the same thing in VB. Basically I can't figure out how to get the try/catch to work with text boxes and input from the user and whatnot.I've tried setting the textbox.text property = "" but that has no use, I've been trying to find something on Google about it but I cannot seem to find a single thing about textbox try/catch statements. Is it possible to do it with text boxes?

View 7 RepliesIs there a simple way to save user input from MANY controls (textboxes, comboboxes, etc...) to a text file? When I say 'MANY', I am referring to at least 580 textboxes and several dozen comboboxes.
I may be able to accomplish this using the StreamWriter Class, but doing this individually would take quite a long time. I suppose I could also change all text boxes to richTextBoxes and save to .rtf. It seems like this would be even more time consuming.
Surely there is a simpler way to do this 'globally', perhaps with an added single line of code that points (and saves) to a preset or created text.txt file whenever text is added or changed in a textbox or combobox throughout the program.
I have a text box labled QTY, which feeds the QTY column on a datatable. the table then is ran through a function that takes the data and converts it to a string which my production machine can read. My problem is this, and its probably really simple (these problems usually are) how to i force the user to use a specific type of input on the txtbox so they would have to put the QTY in the format of 01 02 03 etc etc, i have it set to default to 00 but i want to force the user to haver to input 2 chars.

View 4 RepliesAny way to change the case of a string using the String.Format command. For example, you can do this:
String.Format("{0,50}","My Info")
And it gives it a fixed width string output, I need to allow the user to change the case. All they can pass in is the format "{0,50}" so NO .net functionality, we wrap it up for them. In VB6 you could use a ">" "<" to change the case, surely M$ must have added a way to do this?

I am making a program that calculates various results with variables entered by the user. What I am trying to do is incorporate a function that will allow the user to switch from metric to imperial easily but only when the ok button is pressed. Now I got all the coding done for the metric and everything is working fine. My problem is when I use the radiobuttons to switch the entered variable in the text box to the desired unit it gives me a 0 or a random number in the textbox...
I also have labels indicating each variables unit which I easily managed to change with the text box using this code. :
'Change Labels to Metric
lblMDegreeC.Text = "Degree C"
lblMDegreeC2.Text = "Degree C"
lblMmm.Text = "mm"
lblMmm1.Text = "mm"
lblMmm2.Text = "mm"
lblMm.Text = "m"
lblMm2.Text = "m"
lblMm3.Text = "m"
lblMDegreeC3.Text = "Degree C"
I created all the coding to convert the metric variables to imperial. My problem is changing the textbox text when the user switches the units during run time. The labels change without a problem but the textbox never works. I have attached the coding for the file.
