I'm rewriting a legacy application in .NET. In the earlier version, I used a few control .INI files that could be edited by the advanced user to provide variation in certain program options. (The program also permitted override of these same variabes via menus and such.) I used the API functions to read the .INI files and rewrite them to alter the user's environment for subsequent runs.
View 19 RepliesIn the program I'm working on, there is a 'sign-in' form that pops up for the user to enter first name, last name, and DOB. What I want to do is STORE that information in a text file for FUTURE use by the program (i.e. displaying a list of all previous users of the program).I already know how to use streamwriter to write text to a file, but I would like for the text file to be stored within the program files and also for a new user's data to be appended to that file every time.
Do I simply add the text file to the project files? When I do that, its path is 'My Documents'. How will that affect the program when I publish it? I guess I just don't yet understand what happens when the program is finished and published. The code for the 'Submit' button on the sign-in form is pasted below. At the bottom, I've put a comment to indicate where I want to store the data to a file.
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim TxtBox() As String = {TextBox1.Text, TextBox2.Text, TextBox3.Text}
For i As Integer = 0 To 2
If TxtBox(i) = Nothing Then
[code]....
Here is what I would like to do:
- Store string data from a 'sign in' form into a text file. This text file must be one that is saved even after the user exits the program. The text file must also be one that will stay with the program even after it is published (executable).
- Be able to write to/read from the file for purposes of displaying some or all of that data on a form.
I use an Application Setting to do this - of type 'Specialized String Collection'. I tried this, but for some reason I could not get it to work. It was a good idea, but I need to be able to SEE the data that has been saved, and with a setting it seems like that is not easily done. I've decided that I either need to use a simple text file or a 1-table database for this. I would prefer just a text file, but in either case, it needs to be part of the .exe when published.
I have added a text file to my project, but I am not sure if it will be "included" in the project when I publish it. The path of the file I've added is in 'My Documents', but in my code, I will have to specify the path in order to use Streamwriter. How will this affect the program when I publish it? I felt the need to make a new thread because on my last one we had been mainly talking about settings, and I've decided that isn't the best option for me.
I have been tasked to create an application, for which the requirements may change over time.This application will be a data entry Windows application,of which multiple copies will be running.All data will be written to text (.CSV) files for validation before being uploaded to a remote mainframe system (iSeries).My application needs to store certain variable information in an external text (or XML) file; for example, the file path to shared resources (which may change over time),as well as the specific data fields required by the mainframe system.
My questionsare these: what is considered the best practice for accomplishing such a task, and how would I accomplish it?I am completely new to XML, so I don't even know where to begin, although I am sure that XML is the path to follow for what I am trying to accomplish.
I am trying to code a delete button for a browsing program based on data from a txt file. I have coded the buttons to sort(ascending and descending), append to the text file, search the text file, but I can not seem to get the delete function working. I am using VB 2010, this is what I have so far:
Code:
Dim deleline As String
Dim line As String
Dim isFound As Boolean = False

I have a .net program that you open, enter a bunch of information to control equipment,ovens, etc. After the user enters all of the information for the equipment/test, they run the test, data is taken, and they close the .net application.However, if they want to run this same test again, I don't want them to re-enter everything b/c it would be quite tedious. Instead, I would like to have a file > export and file > import option. I am going to import/export from excel.
I have set up a blank template in excel that has a lot of formatting and descriptions. My question is, where do I put this template file and how do I reference it? For example, do I save it in the project's inRelease folder? Then when the user goes to file > export, how do I refernce it as being in the inRelease folder? After making an installer package where does the template file get placed on the install if its in the inRelease folder?
I have an ArrayList that stores 100,000+ numbers inside of it. Each number is 10 digits in length or smaller. The program itself has data input into it, of which it loops through the user input to see if any of their numbers are already in the array using if ArrayList.Contains(userinput).
It would appear that when having an ArrayList of this size a LOT of memory is being used. Would there be a faster way to run this, E.g. Database or If TextFile.Contains(Line)?
I'm trying to write a vb.net application that works with a 3rd party application called FuzzyTech. Unfortionalty FuzzyTech is quite old so the only way I can interact with it is buy using DDE. FuzzyTech acts as a DDE server. After a bit of research I found a library called NDde which enables me to use DDE. I understand that vb.net does not natively supprt it as it is an old technology.
Now fuzzyTech seems to only respond to the DDE connect and pokes when in debug mode. The only way I can find to get the program in to debug mode is from the menu bar (Debug > Interactive). So I have written an application that runs fuzzyTech, grabs the window and then accesses the menu to put it in to debug mode. My code can then use DDE. I have all of this working ok (although it does feel like a bit of a hack). The problem is I don't want users to be able to see this happening.
I want fuzzyTech to be hidden.After more research I found I could hide the window on startup by using fuzzypProcess.StartInfo.WindowStyle = ProcessWindowStyle.Hidden. However when I do this my code to grab the window and send the menu commands then fails. I think this is because the window title becomes blank when hidden.So I need to know a way of controlling the program after it is hidden or hiding it after it is in debug mode. This is where I am stuck. I'm very new to programming and this has got me completely stumped.
Here is some of the code I am using:
Private fuzzypProcess As Process = New Process()
Private Sub LoadFuzzyTech()
Try
fuzzypProcess.StartInfo.FileName = projectPath & projectTitle & ".ftl"

View 2 RepliesWe decided to use the registry for handling our deployment with connection strings in our VB.net application.
The requirements are:
If the program cannot connect to the server, first check the registry for a connection string. IF not, create the folder and fill in the name, type, and data. Make sure its encrypted.
I have never edited or created anything in the registry.
I am trying to store 8 separate pieces of information in a text file (like a database) [but not a SQL database], consisting of integers and strings. How would I use an array to do this? Will an array collect data from text boxes (I also want to display the 8 pieces of information in separate boxes). also how would I save the text file so I can open it again or open a different text file (database?), from within the program?
EDIT: I see I need to use readline and writeline to read/write from a text file but how would I find specific data to show in my boxes?
My xml files were looking a bit clumsy when i read them, what i have done now is to save them in the xml in this format:

i noticed {|} this is the format that vb.net uses for arrays, i was wondering if that's an ok way to store things, on retrieval once i get the node value, what would be the best way to break up the {value1|it's partner value2} variables to use, explode the | and get parts (0) and (1)?

View 4 RepliesI am writing a backup program that zips files. Using some sample code I have the following that creates a zip file. Problem is it does not get any subdirectories or files. Where am i going wrong?
Dim azFileNames() As String = Directory.GetFiles(SourceFolder)
Dim objCrc32 As New Crc32()
Dim zipStream As ZipOutputStream
[CODE]...
Alternativley, there is another component to the zipping dll that I could probably bypass the above altogether. It is: FZ.CreateZip(DestFile, SourceFolder, True, "", "") Where DestFile is (Output stream as system.io.stream). I'm trying to read all the files, directories, sub dir and files, etc from a specific location, let's say 'My Documents' into Destfile in which the FZ.CreateZip zips the file. FZ is FastZip which is from icsharpcode.net. They have c# examples, but that's greek to me. I'm trying to just learn VB!

When i open the file, i want to redisplay the data in separate text boxes. Later on in the project i want to be able to search within the file for headings for example;
if "[Heat1]" is present then get all text between [Heat1] and [Heat1]
i am currently able to use the streamreader and open file dialog to retrieve the entire string of text fromthe however i am not sure how to go about getting the text between the headings I have used.
1 List all of the data from Teams.txt in a Listbox. Include suitable headings.
2 List all of the data from Results.txt in the Listbox (use the same Listbox as in 1 above).Include suitable headings. Note that you cannot assume that the file contains onlyresults for the first 3 weeks of the season. Your program should be able to process a results file with more or fewer results.
3 List all of the data from Results.txt in the Listbox. However, in this case the actual team names should be output (your program will need to get this data from Teams.txt. The data should be formatted so that it is aligned correctly. Include suitable headings.
The output might look as follows:
Home Team Away Team Home Team Goals Away Team Goals

I have a variable (double) that is constantly update in real time with data from an analog input. I would like to write this data as it comes in to a txt file. When I stop my acquisition of data from my analog input, I should have a txt file with all that data stored on my computer wherever I want it. The way I'd like that txt file to be laid out is like so:
Test Title: "This info comes from a string variable"
Operator Name: "This info comes from another string variable"
Test Date: "This info comes from yet another string variable"
[code].....
And so forth. As you can see I would also like to write the time for each data. This depends on my Timer interval which the user can set. The default is 50ms. So by default, y1 y2 y3 would be 0, 50, 100. How would I generate such a text file?
PS: I have five variables (X, Y, strTitle, strName, strDate)
