I need to be able to view another programs chatlog while it is running. this is the existing code. right now for testing it just reads the first line of file. this reads the file just fine as long as the other program isnt running but if it is running i get an error stating that the file is in use by another process. I'm using vb 2010 express.

So I'm in the final stages of finishing a program I've been working on for nearly a year now, and this is basically my final hurdle. The Save dialogue is working beautifully, with 'flags' in order to switch it over from the regular input into text boxes to the Listbox input protocol.
However, I'm having a *** of a time getting it to take lines from the text file and put them in the proper text box. Here is an example file:
Quote:
SHOWNAME
CALLNAME
BREED
[Code]....
So with the sample file I provided above, in the textbox named callNameText would appear "SHOWNAME", and so on and so forth. With this build, I get a NullReferenceException on the "Me.Controls(strboxNames(i)).Text() = strAllText(ati)" line.
So essentially, I have this text editor. How can I make it so when I drop a text file over it, it opens it in textbox2? Or when I doubleclick on the file, it automatically opens it in my program (in textbox2).
View 21 RepliesI'm having a slight problem getting my program to load a save file when double clicking the save file.I'm using the Command$() to get the command line argument. I can open a save file by dragging it onto the exe. But not by double clicking the save file (after it's associated with the exe).I though dragging and dropping a file on a program and double clicking the file would open it in the same way, but I guess not.So in short how does file association work and how do I get the file path set to a var when the program loads.

I'm having some trouble using resource files. In my project I'm using a bunch of bitmap files and two txt files. Bitmaps are used as backgrounds for controls, but .txt files I want to open in Notepad or WordPad. Till now I was accesing them from a file path on my machine:
ControlName.backgroundimage = New Bitmap(direcorypath & "/Map.bmp")
Process.Start(direcorypath & "/Instrukcje.txt")
And it worked fine. Now I added these files to my resources (it's practical for me to have them in executable file) And replaced those lines with:
ControlName.backgroundimage = New Bitmap(MyProject.My.Resources.Map)
Process.Start(MyProject.My.Resources.Instrukcje)
For bitmap it works fine, but for txt file an error occurs saying that a file cannot be found.
Interestin thing is: when I type "MyProject.My.Resources.Instrukcje" in "Watch" it shows the content of the file. So it is there, only not as a file?
I have the following code used to enter the name of a text file and then display it in a richtextbox.

There are going to be 300 words. Really I'm just testing it right here. What I want to know is should I be inputting all the words right into the code like I did with "hi" and "not 1" (Don't ask. those are just the 2 random words I picked to test this out with). OR is there a better way (maybe somehow to type all the words on a text file and have the program randomly pull one of them (I don't know how to do this).

I have a program where a lot of the required information for it is stored in text files. I simply read this information into large arrays. However, I don't think it's necessary to load all the information each time. Rather, it would be more efficient if I could simply search through a list of items to find the one I need and then use the data from it, or to find a similar name and use it elsewhere.
Would I be right in using a database? And is database programming done in SQL? I have a book on it telling me to use the SQL Server (IIRC), so I shouldn't be doing it in the VB.NET Express GUI?
Here's an example of what I would do:
Hex = 03 00 => dex number 003
Search in file Pokemon Dex Numbers
003 returns Bulbasaur
Check Bulbasaur base stats in the base stats file
etc
So basically I'm reusing a lot of information. I think a database would be best and it would all be internal right? I'm getting complaints about access denied to a text file (since it's stored in the program directory in the program files).
So to cap up the few questions I have:
-Databases are done in SQL and not inside the GUI?
-Databases would load internally?
-I could search a database without having to load it into like an array or something?
I have this Quiz software that lets you create online multiple choice quizzes which are great for studying (I am in grad school and I'm trying to use everything I can to learn). So the Quiz software is great but it only lets you input questions by hand, one by one. I took a look at the .xml file that the quiz program spits out and came up with the idea to try and make a converter so that I can import many questions at once. I was hoping to try and solve this limitation by doing the following:
Take a .doc that say a tutor gives us with a bunch of practice questions, and then take that into Crimson Editor, and then format it so the question is on line 1, the multiple choice answers are on lines 3,4,5, and 6, (for the next question, the question would be on line 11, and the answers on lines 13, 14, 15, and 16, and so on) and then take that saved .txt file into my program, hit the generate button, and it will spit out the .xml file, and then import that into the quiz software to generate the online quiz.
Here is an attached screenshot of my program layout so far:
I figured out how to open a text file by watching simple youtube tutorials, but I don't know how to have it generate the stuff and have it show up in the bottom text box. I know how to do the coding to convert the txt to proper xml code but I don't know how to be able to save the contents of the bottom text window to an xml file.
