I am trying to create a console app which is a TCPlistener however whenever it receives any data and I write to the console window it gives alot of 'enters' (blank lines) which is not what I sent at all.
Example:

_writer.Write(toSend, 0, toSend.Length)

View 6 RepliesI'm implementing a feature which reads comma separated txt file from server(one line at a time). Format of file is fixed, There are 3 columns on each row. After reading the row from file I insert it in a database table. But first value of each row aoutomatically appends two blank spaces, even if there are no blank spaces at the begining of each row. I tried to use "TRIM/LTRIM/Replace" to remove blank spece from the first value of each row, but didn't succeed.

I have a notepad txt file that has two columns of data. Vb reads data having one blank space (this is in column one) but ignores any other data beyond two blank spaces. in addition to being able to read the second column, I want to store the data thats in the column 2 in a separate string.
View 5 RepliesI just changed a control on a form from a masked textbox to a normal textbox because I wrote my own code to validate the data. I'm trying to clear the leading spaces that were created for this column in an Access database using the LTrim function and it doesn't work for some reason. The column is " :30" in the table and when I LTrim it and save the changes, it's still " :30" , not ":30". Is that leading entry not a space character?
View 4 RepliesRegarding a console application and VB forum program - In searching XML parsing examples I find several using Console.Write and Console.Write - To show my inexperience I (out of habit going through a couple preliminary examples) I created a new VB project with a blank form - I then copied and pasted the XML example using the console commands Errors - I just found the "create console application"What is the difference between a console application and the project using a blank form? Can the console commands like Console.Write work with a VB form project?If so (#2)What is the advantage in creating a console application - why not just start with a blank form and go?

View 8 RepliesOK, SO i have this program that outputs all the servers on a specific game. It outputs it to a text file. HOWEVER, There is a lot of annoying spaces. This is kind of hard to explain, so ill try to explain it. This is what The text file looks like. [Code]
As you can see, they have these annoying spaces. What I want to do: 1. Get rid of the spaces, BUT KEEP A SPACE BETWEEN THE IP AND THE PORT. 2. After the spaces that are bad are gone, I want the program to output each single IP AND port To its own text Box. It doesn't matter is the textbox of the IP and Port are separated, It can just be one textbox with the IP and port, with a space between them. Thats about it. I have the GUI done, and the rest of the programming, all I need now is this. Reformat without spaces > output each separate line of text to a separate textbox > TYTYTYTY
PS, is there a way for VB to send a command to the command prompt? Say, I wanted it to open a CMD box and send ipconfig into that box, what would that be?

View 3 RepliesI need to write a program in VB 2008 express that takes an user entry from a textbox and strips out all the spaces, changes it to either all upper case or all lower case then checks to see if it is a palindrome.

Basically I need it from the button click to the end. ?
View 3 RepliesThis combo box is databound to a SQL backend, so when it is filled it has a blank at the top of the list. I am assuming this is added because of the NULL at the bottom of the SQL table. Is there a way to remove this entry?

.items.removeAt(0) ' This gave me an exception stating that it could not be used because the datasource was used This is the code i use to fill the combobox on form load:

I was thinking of adding a simple bandwidth monitor to a console application and I was wondering if it would be possible to keep a line in the console window visible at all times. I could set something up manually to pass new console output into a method that would get the contents of the console, clear the console, add the bandwidth data on the first row, then rewrite each line of previous information back to the console, etc.. but that seems like a really hacky way to go about it, and I'd be limited to the amount of rows visible at once in the console window (no scrolling).

I had created a media player using directx. It works perfectly even with resizing the form but I having problem when I minimize it. I use panel as the owner of the video and after I minimize and change it to normal state, the panel goes blank but the sound goes on. Then I get an error in application notification by VB2008. There might be something to do with the graphics where I dint handle it when I minimize it.
