I'm using vb 2010 express and composing a program that is using english and hebrew. The problem is the hebrew characters are not showing up in vb when reading the file I stream to. I would like for it to show exactly how I have it written in the text file.

I have several fonts I want to include in my program to be used, or just want to put them in a folder with my program, or some method of adding them to the program without having to install it on any PC that I want to use the program on.
So basically I want to Either
A. Include the fonts in the program so the program can use them
B. Find a way to have the program use the fonts without them being installed on the PC.
I am having a _ton_ of issues, and I am hoping some of you could clear it up...
1. OK So a while back someone showed me an example for fonts from resources, but I noticed if you close the window that it opens, The entire program shuts down... what can I do to fix it?Also, The fonts are not showing up on all computers, only this one....
2. I am trying to delete a image file, which the program downloads from the internet, and can change regularly, but when I try to delete it will not delete. It says its in use, and I cant figure out where.
3. I am trying to play videos using the following
vb

Const WS_CHILD As Integer = &H40000000
[code]....
Now, I have confirmed the files it is attempting to play are in fact valid video files. It refuses to play all but the last one.

View 11 Repliesin my project, i want to read an ini file - i.e. C:xyz.ini
ini contains:
[0089]
Vendor=INTEL
8874=28F640W18TE
8981=NU48F256
8982=NU48F512
I can read through usb - i.e. phone id : "89820089" Now 8982 should = to NU48F512 as we have it in ini.
I have a problem and hope someone have idea to rsolve it. I have a file and inside the file the format is like that :
123.567 456.789 12.345 223 223 221 223
123.555 456.788 12.344 223 223 221 222
123.456 345.678 456.234 445 445 445 445
total line is 3456789903. I want use vb console application to read the line and every 130000 line create a new output file.
I need to read lines from file. Now my code is like this:
Sub data()
Dim reader As New IO.StreamReader("log.txt")
For i = 0 To 1500
date(i) = reader.ReadLine
Next i
End Sub
Now if some user will change add or remove the data from this file, it will end up with error or sth. I also tried to write sth like this:
Open "C:in.txt" For Input As intInFile
But there appears an error, that open is not declared and IO functionality is microsoft.visualbasic namespace. I added this name space (at the top: Imports Microsoft.VisualBasic), but this error still occurs.
My question is a rather simple one and to be honest with you, I am not sure if it can be done. Lets say I have a mutli-line text box, is it possible, and if so how would I go about making it so if I clicked Open with > editor I could do things with this text, such as TextBox.text = [file contents]. If it's not possible just let me know and I'll stick with open file dialogs.

I created an application that I use when deploying packages which allows users to postpone it from running until they are ready. There are two text boxes that contain restart warning messages.
Is there a way I could use an external file such as an INI where I could place a different message? If the app could read the messages in the text file at runtime and place them in the appropriate text box, it could make this app a little more flexible.
As it is now, if managers want the message changed, I have to change it in the source and recompile. That is not a good way of accomplishing the change.
I'm trying to do is read a text file from a certain line to the end of the file. For example, say the text file is:
Hello
Everyone
My Name
Is Tyler
I would like to be your friend. Would you be mine? I like dogs, cats, and basically any animal. I play the tuba and am in a band at college. I go to UMass. Do u like UMass?
(none of the above info is true FYI)
My code would look like this:
Dim hello as string= io.file.readlines(c:/text.txt)(0)
Dim everyone as string= io.file.readlines(c:/text.txt)(1)
Dim myname as string= io.file.readlines(c:/text.txt)(2)
Dim istyler as string= io.file.readlines(c:/text.txt)(3)
But say I wanted it to read from line 4 to the end of the file? The entire description I would want to save as one variable. How would I do this?

I'm currently making a program in Visual Basic 2010 for my Course work, and I'm struggling a little as it involves a "log-in system."
The system will save the Users Information in a folder (Called UserInfo.txt) (Address, Password, Email etc..), and the folder name being the username of the User.
When an Admin wants to view or edit a User, I want the Admin to be able to select the User from a drop-down list and when selected, the information of the user loads in and is displayed in the text boxes bellow (on the same form). The Information can then be edited and Saved back to the file of that user selected with a "Save" button.

I'm working on a new application for one of my Managing Editors at my company. We are wanting to build an application that only has 4 combo boxes for user options and then according to the options that the user selects, the application will spit out 3 random lines of text that can be copy and pasted into another application that we use.We are in the process of creating a rather large (1000's of lines) CSV file that we are going to use as a repository for the text. Let's call the data file SRG9000Data.csv..I'm almost 100% certain that I'm going to need to read in the entire datafile as an multidimensional array because we are setting up the CSV file as follows:[code]For each of THOSE categories, I'm looking at having 8 possible items for <Sports>, and 3 items for <PlayType>, <GameImpact>, and <Scoring>. <Text> is being use as a possible Text Phrase that the system can select from randomly provided that the other area's of the array are met.The CSV file will have 1000's of lines. Of those, the system will "filter" though all of them so that ONLY the ones that meet the selected criteria can be used, then choose 3 of them randomly and use that as output.
Extra information: I am currently establishing that the CSV file being used is setup as 0-7 for <Sports> (0 = Baseball, 1 = Basketball, etc..), 0-2 for <PlayType> (0 = Defensive, 1 = Offensive, 2 = Other), 0-2 for <GameImpact> (Negative, Neutral, Positive), and 0-2 for <Scoring> (0 = Non-Scoring, 1 = Other, 2 = Scoring); <Text> is a String.I am clueless when it comes to setting up an array like this; It's been many many MANY a year since I worked with array's in QB and I feel I may need more than a refresher course.Now, if I'm understanding correctly from some of the forum lurking i've been doing, multidimensional arrays CANNOT be of mixed type, correct? If this is the case, the how can I read the entire CSV file into an "array" (if you will) so that it contains Integers AND a String? [code]
