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 was just wondering if there was a way that i could compare data stored in a text file such as usernames and passwords with data input into text boxes in visual studio vb2008?
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 cannot figure out what is wrong with my code. Yes I understand its giving me 4 error messages about visual basic 2010 Express seeing some of my variables as undeclared. Below is the code.
Ok, i've been making my own syntax highlighter for my project, and i need to know how to make the colour of the text between these two text values green
I want to use text to speech to say what is in my textbox. I have added the reference into the solution (MS speech object libarary) and inserted the "imports speechlib but i am getting an error when building.

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?
What would be the fasted method of get a string list of all values within [] in a string of text? For example: [client_name], are you are doing today? My name is [my_name]. The list of strings would be:
How would I get a textbox to contain the text of a TXT file stored on the web? For example, lets say I have a website. I uploaded a TXT file to it. How would I get the text from the TXT file and display it in a TextBox?
Is there a function or something that is built into VB.NET so that when I save a text field (of a user's input), malicious code isn't being executed in the process.
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)
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).
I am new to visual basics. I have loads of text files stored in a folder. I only want to chart some of the columns in the text files. How do I use visual basics to charts the data?
class to be used to print a paragraph of text that is to be printed on a printer, In vb.net, more than 1 page of text must be dynamically printed by retrieving data from the database.
I have textbox "tb1" on my page and I want users to be able to add another if they need to input more data. I have the following [Code]. My problem is that I can only add one text box each time and I also have a search button for the right panel on the page and if this button is clicked the created textbox will disappear.
I have only 1 Label in my form. There is no text in Label1. I want that when I run the project, the label has any word or number in it like '1'. I want that when I run the project again, the word or number in the label should be changed to '0'. The name of my label is Label1.
I would like to bind textboxes to certain columns from records generated from a stored procedure. The error I receive is "DataMember property 'spCustomerHeader cannot be found on the DataSource". I have no problem returning the data to a datagridview but I need this show this data in textboxes.
I want to create a very simple database. form1 - ListBox1, textBox1, buttonadd, buttonremove. The item collection of the ListBox1 is stored in a txt file along with a string that will be displayed in the textbox1. the file will look like this ( like a .ini file):
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?
Private Sub Add_Click Dim tbox As New TextBox tbox.Location = New Point(12, 244)
[Code]...
I added a textbox dynamically during runtime. How will I add the text in the textbox to my database? The name property of the textbox cant be change. What is the name property of the texbox created during runtime?
I am using VB.NET vb 2008 . I am trying to create text boxes dynammically and remove them here is the code i have written so far
Private Sub setTextBox() Dim num As Integer Dim pos As Integer
[Code]....
