Text Values Are Not Stored At Text Box Declared Dynamically
Jan 13, 2010
I have declared an array of text boxes created dynamically at run time. The textboxes are assigned some values by user. The text boxes are located in a Form so that once the user fills in the info and clicks the "ok" button, these values are passed at the back end and the form dissappears. However the user can bring back the form again by clicking another button.
The problem is that once the form reappears, the information previously provided in the form remains. Even the user clears the text boxes to provide new value, the text boxes at code behind do not receive these values.

Need to design a program that can encrypt and decrypt messages stored in simple text files using a private key stored in a separate file. Software should also be able to allow the users to enter simple messages that either displays the encrypted or decrypted message. The encryption method should use a simple substitution method. It should be set out in the following format:
Example (the "@" is the separator):
@
The character The Code End of line
A @ 4gh EOL
B @ 84!9 EOL
Has to use the 256 ASCII character codes. The separator will be used to separate the character and its corresponding code.Here are the pseudocodes I have come up with:
� Read any private key file
separator = readline(file);
while not EOF(file) do
tempStr = readline(file);

I have to save the text boxe values of a form to a text file almost like a data record. I will be saving an Employee First Name, Last Name, Dept Number, and Phone Number. This I know how to do using streamwriter.
next form which we have to use stream reader to load one record at a time. The form has a next button to load the next record. How do I seperate each record (I am sorry for calling it a record if this is inappropriate) when use streamreader and how do I load a record at a time.
I know how to open a file and use streamreader, I just don't know how to read one record at a time and move to the next one.

I am trying to use a checkbox that is dynamically declared in an .vb file that I am trying to write into my .aspx page. I am able to write a normal checkbox of <input type='checkbox /> from the .vb Class using Response.write, but it comes up blank when using <asp:Checkbox runat='server' />I need to pass whether or not the box is checked back to the server, because I am having to either approve something if one is checked, reject something if the other is checked or do nothing if neither are checked.

I am dynamically declaring types (using ModuleBuilder.DefineType() which are used to allow for strongly typed data sets from a CSV file. However when the user adds or alters a column definition I'd like to remove and rebuild the data type. How I drop and recreate a type - do I have to unload the whole assembly or how is it done?

I'm trying to find a way to change the name of a text box if the name of the text box is first declared as such:[code]I tried the statement: Name = "SBox" & My. Settings. Row Countx but maybe this is wrong.To be very brief I'm trying to resolve this to under the following scenario:
1. Add a new text box to a tab page when user selects "add" button.
2. Each text box must be assigned a unique name
3. Data entered in each text box will be then be saved in my.settings (i.e., for each text box, there will be a corresponding variable/name to hold its text value)

In my form, there is 1 Button and 1 Label.
There is no text in Label1 right now.
I have coded the button:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Label1.Text = "1"
End Sub
End Class
Now when i run the project, i click on Button1 and Label1 has text in it "1" as it is in the code.
I want when i again run the project, the text in the label should be changed once i click Button1.

I have a text box that I need to be filled from another form (a search window). I would like to call a function and pass the text box to that function. What is the best way to do this? I think I can just pass the text box as an object. Or I could use an API. I may even be able to pass some kind of handle to the text box. Let me know what would be easiest (I would prefer to avoid API).

One of the features of my new Vb game is the ability to modularly add and remove in-game items. However, in order to add these items I figure their effects should be recorded in code in the text file they will be stored in.In short, I want to store code in a text file and then have it run on command
Furthermore, is there a way I could put all of the code on one line?
