Load A Lisbox With Data From File. Save Data From Textbox To File?
Dec 10, 2011
I have a form with a listbox that when the form is opened I need it to display info from a file. I don't know what would be easier to work with Excel or a txt file, but it is in this format:
Phillip Frank
3/19/1990
3
999-555-8618[code].......
I would like it to populate the list box when the form is loaded, but if I have to use a button to tell it to load that is fine also.On the same form I have 4 textboxes that ask for each of the above items (name, DOB, Level, PH#) and a button that when pushed I want it to save it to the same file where the above info was pulled from in the same format.The Show Contacts button doesn't have to be used if it is not needed.

How do I get it so that when I click a button on a windows form, it exports the text in a textbox to a .txt or .xml file. I need it to add the data to one text file, not create a new one every time the button is clicked.

I have an application that pings IP addresses. When complete it will probably have close to 1000 IP addresses it will ping. I have a settings page that has a textbox that stores the IP address (one IP address eg. 192.158.1.1 per text box) for the object to ping. I want to be able to save all of the textbox IP address into a text file, and then be able to load the IP addresses from the text file into the respective text boxes.

I have an issue where I need to load a fixed-length file. Process some of the fields, generate a few others, and finally output a new file. The difficult part is that the file is of part numbers and some of the products are superceded by other products (which can also be superceded). What I need to do is follow the superceded trail to get information I need to replace some of the fields in the row I am looking at. So how can I best handle about 200000 lines from a file and the need to move up and down within the given products? I thought about using a collection to hold the data or a dataset, but I just don't think this is the right way.[code]....

I am new to using visual basic 2005. I have a tutorial book and I have followed it but it does not help me understand. I have a limited understanding of the net framework and the drag and drop features.
What I want to know is this: How do I make a simple name and address tracker file that I can enter data and save it as a file. The book does not cover this proceedure but It is what I want to do.
IE: Start VB2005 start new windows app. Name (whatever) drag 2 label's and 2 textbox's and one button for saving data entry. I want this program to enter name in textbox1 (press enter) then enter address in textbox2 (press enter) then save file (whatever name) when you click the button.

I have about 4000 objects of a class, each object with 20 members/variables, integers and strings, total about 80000.
I would like to save these to a file, and read them back into objects when the program starts up.
How would I do this in order to keep track of each variable? I was planning to have each line in the file representing the variables of 1 object. Hence 4000 lines. But basically I'm just looking for the easiest way to save and retrieve this data. Should I first convert the objects to an array of strings?

I tried the tutorial on here but got completely muddled up. Why can't it be easy like in VB6 When it was like 10 lines of code tops!

The program is finished I am on testing part. But I cant run the program. What happened was since I did this I got new PC so I had to install everything from scratch.. So now after downloading the mysql .net connector to connect to database and installing it i keep getting this error
"Could not load file or assembly 'MySql.Data, Version=6.1.3.0, Culture=neutral, PublicKeyToken=c5687fc88969c44d' or one of its dependencies. The system cannot find the file specified."
I tried everything Installed every single past version of the .net connector but I still keep getting error. I tried this on my laptop and even my new pc (which is 64bit so I thought thats the problem) but since I get the same error on laptop I don't know what else to do.

Tag and image files. All my files are .gif files and all have the same format. However, some of my 'objects' are located at different positions on the image. I would like to store the position in a Tag and save the Tag with the file. This is what I did..
Code:
dim pathload As string = "C:\myfile.gif")
dim picViewer1 As New PictureBox
Sub graphlocationsave()
[Code].....
I know the data get store in the Tag, but I do not know if its not saved, or I am not retriving it correctly or if this is the wrong way to do this altogether ?

I want my app to load a .exe file specified by the user, crypt it then save the crypted .exe file on a path also specified by the user. I need some guidance on this. First of all, I am currently using IO.filestream to store the .exe file. When I save the completed file (so far in development, that means a copy of the file as I haven't added encryption yet) the .exe file appear there alright, but without the icon (it has the standard/no icon instead) and it does not work. I tried outputting it to a .txt for examination and it was a bunch of tokens as one would expect. Here is the statements:
