Working With A Text File Inside My Project
Feb 22, 2011
I have no code specifically for this part of my project just saying this ahead of time.I have not used text files that are inside my project but I want to be able to open the file when I load my form and save it when I close my form.I know how to save manualy and same with opening but that defeats the purpose this has to do as much as possible on its own.All I have are code from a project I made a while back which was a notepad program.[code]however I need this to all happen on its own and it needs to install these text files with the program hence why they are in with the project there are about 30 text files that will need to be with it so if I can get help with one then I can figure the rest out.

I am currently working on a school project in VS2010. I have added a .exe file in the project folder and added it to the Project as a 'Existing Item'. In Project Properties -> Publish -> Application Files the .exe file is shown.
The .exe file runs quite nicely when I use the Process.Start("C:\NameOfMyApplicationFolder\MyProgram.exe") hard code path to the .exe file. However, I am faced with two(2) challenges that I need to overcome. These are they:
1. If published on another machine the .exe file will not run as the hard code path to the .exe file will be different from that on my machine. Therefore I need a way to create a generic path to the .exe file. I have tried these [Process.Start("C:\|DataDirectory|\MyProgram.exe")] AND [Process.Start("Localhost\|DataDirectory|\MyProgram.exe")]; I got an error message that "The system cannot find the file specified".
2. I am putting the Process.Start("xxxxx.\MyProgram.exe") on a button click event. I also want to put the running of the .exe file between two(2) lines of code. The first line of code is basically asking "Do you wish to run the executable file" - YesNo. If 'Yes' is selected the .exe file is run. Here is the problem: When the .exe program is closed the second line of code is to be executed. I have gotten the .exe to run (using the hard code file path) when 'Yes' is selected, and the second line of code to execute if 'No' is selected, but I have not been successful in getting the second line of code to execute after closing the .exe program. I have tried this: [If Process.Start("C:\NameOfMyApplicationFolder\MyProgram.exe").CloseMainWindow = True Then Do line 2 End if]. nothing happens when I close the .exe program.

I'm trying to open a text file that was already generated with info inside.I want to read specific lines and have them changed via user input.the lines are not consistently on the same "line".An example of the text I'm trying to read and change is:
// General (upgradeable) values the Player sees for each system
hullLevel = 1700
weaponsLevel = 1450
[code]....
The "H" in hullLevel shows up in line 26 in some of the files, line 27 in other, line 36 in some others and line 37 in yet others.
The reason this jumps around is that this comes from a file that is edited by other modders when they create a ship for a game that I'm modding.My program is designed to allow the user to visually see a representation of how strong and well equiped a ship is and change the values of each line with a slider bar.I have all the slider bar and progress bar code worked out.
I just need a way to reliably pull these lines no matter where they are from the ship file chosen by the user so that the program can edit them without disturbing the rest of the text in the 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?

Not sure if there is a better way to do this but this isn't working. Just trying to run a batch command "query session" and put it into a text file using "> sessions.txt". When I run this command in a command prompt it works fine and spits the output to the text. I've tried just making the batch file in the same folder and executing that with Process.Start, still empty text file. Tried modifying the loop and no go also

Is there a way I can open and read a text file within a .NET project? I know I can use the System.IO.StreamReader class to do it for a Windows text file.I'd like to store some SQL scripts for upgrading my database in text files within my project. Since I'm writing this in VB I can't just paste the scripts directly into my code due to line continuations, where I could if it were C#. These are very long scripts.

im new to coding (started coding last month) so im a little stuck on how to do this, im making some emulation programs to learn coding with, and a part of it is to point the app to a .iso/.bin file and scan the data inside of the iso/bin to check if a file exists.[code]My issue is i cant find any class examples, or any information etc on how to code it so my application can see the data inside of the iso/bin instead of just see'ing the iso/bin file, so that i can then check the data inside the iso to see if the file exists etc.Im a novice still at coding so making a new class myself to look inside the iso/bin is to complex for me.

I'm trying to include a few text files in my project. These files are read and used to make decisions in the program. Ordinarily, I would just set the file path and open the file via StreamReader, no problem. However, this application now needs to work on other computers and I want to include the text files in the application directory. I've researched two ways to do this:
1) Include the files as resources and reference them via my.resources.
I've gotten this to work ok, except the files are opened as strings upon starting the application. They are fairly large files, which I imagine is taking a lot of unnecessary memory. Also, StreamReader wont work with these files as resources,
or at least I can't figure out how to. My application is already based around using StreamReader so I don't really want to change this.
2) Include the files as additional items. I know how to do this too, but I can't reference the files programmatically.
Can I use a resource text file via StreamReader or how would I reference the files if they're included in my project directory?

I am using Visual Studio 2010 and have been slowly getting into threading. My current project has a form with a button that in turn starts two threads. The form itself has two labels on it that are used to display the progress of the computations. Each thread has a delegate defined to change the value of the respective label (as the labels are not defined in the thread, but on the form itself). The threads call subs from a separate class. All of the calculations work flawlessly. My problem is that the labels do not visually update. Through use of message boxes at the end of each loop, I know that the label text property is, indeed, being changed, but it is not actually refreshing and updating on screen.
My delegate code is as follows (I grabbed this code off of another forum where people had the same issue - it seemed to work for them, but not for me):
Private Delegate Sub UpdatePMLabelTextDelegate(ByVal s As String)
Private Sub UpdatePMLabelText(ByVal s As String)
' Are we in the same thread as the label itself?

I am having trouble binding data to data repeater when I use ISyncResult.This is what I am doing.There is a button inside a Update Panel that gets the input from the user and calls a function that returns a dataset that I then bind to data repeater which is also inside a update panel.What I did is that I made a delegate to this function, now I am calling this function like this
[Code]...
I am having hard time figuring out why the data repeater is showing no data.While debugging this I see that the dataset is getting the data and is passing the the "ds" but nothing is showing up on my page even though the data is being passed to controls inside data repeater while I am debugging.

I have an asp.net gridview that is originally bound to a sqldatasource control, but when the user presses an external button, it instead gets the contents of a datatable rather than a SQLdatasource control. I therefore had to write code in the PageIndexChanging event of the gridview to allow for paging. My code is as follows:
Protected Sub gvEvents_PageIndexChanging(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewPageEventArgs) Handles gvEvents.PageIndexChanging
gvEvents.PageIndex = e.NewPageIndex
gvEvents.DataBind()
This worked beautifully until I added an AJAX update panel so the whole page wouldn't postback every time it paged, and paging stopped working. I debugged it and discovered that it is actually calling the PageIndexChanging event, but nothing is happening. I searched the web and found a few people with the same problem, but their solutions did not work for me. There was one on this site whose problem was solved by the following:
In PageIndexchanging event, where you bind data to grid, make sure, data is again fetched from the DB
I don't know what that means; my data was being bound as demonstrated above. I have "enable paging" set to true and EnableSortingAndPagingCallbacks set to false.
I am including my markup for the updatepanel below.
<asp:UpdatePanel ID="UpdatePanel2" runat="server" UpdateMode="Conditional">
<Triggers>
<asp:AsyncPostBackTrigger ControlID="ibtnSearch" />
</Triggers>
