im trying to make a program to broadcast news on instantly.
It will have Admin interface and User Interface (6 admin users) and (50+ user interface users) Admin interface will have a text box which can be changed and a button which puts changes to the text file User interface will have a text box which auto updates when the text file has changed When the text file has been changed the file system watcher will start which will then re obtain the text file from the path
Below is how the text file writes to the file when a button is pressed
Dim objwriter As New System.IO.StreamWriter("\Svcedfp01Service_Desk$Incident Handling TeamDIHLTESTmajor.txt")
objwriter.Write(majortxt.Text)
I have a program that, at present, reads a set of global variables from a text file. The program is on the client machines (around 100 clients). My problem is that when it comes to the update of the variables within the client program an error sometimes appears stating that the text file could not be read as it is already open (by one of the other machines). Currently I am cutting it down so that only 30 machines read from the single text file, although I am still going to get the error occasionally. Any ideas (apart from catching the error, and trying to read again until it works). Maybe another way to store the variables?
I am sure this can be done, as Visual Studio is basically built this way. What I want to do is simply make a class that my other workmates can use. But rather than have it in a code form, I want to build it (partially), and then my workmate can add it into their programs (sort of, like the add reference for the .NET stuff).
I would like to read text from another programs listview control. I have searched over 3x forums for this and cant find any working examples and especially no working VB.NET examples.I know that i have to use the command 'LVM_GETITEMTEXT' with the API Sendmessage but i have no idea how to issue the command and need a working example to go from.
I Was Wondering Is It Possible To Send Data/Text Across Programs During Runtime. I've Heard Of Something Called API, I Heard It Somewhere and It Sounded Like It Had Something To Do With What I Want. Or Not, I Don't Know. Anyways Heres a simple example Of What I Want To Do
In your opinion is possible to read the chat text displayed in the windows of the several Texas Hold'em Site programs (PokerStars, Titan etc)?[code]...
If I replace "Edit" with all the Classes of the Poker programs shown by Spy++.. the code don't works
In notepad the Class Styles are CS_GLOBALCLASS, in the several Poker programs them are CS_PARENTDC... may be this is the problem? CS_PARENTDC classes don't accept the WM_GETTEXT request?
I am trying to make a tabbed notepad in vb.netWhat I want to do is associate .txt, .rtf, .html, ect. so that when you double click on them, the notepad starts up and loads the text file in one of the tabs. So far I can only get the files to open by using an openfiledialouge
I started with VB 6.0 back when i was 14, I was mostly into coding programs that interacted with other programs. Recently I installed VB.net 2005 pro i got from school, and i grabbed few source codes that teach show interaction, I feel so dumb, i dont remember anything lol. It be great if you guys can share some source codes and other stuff in this field. also other day i was in dream spark and i am able to get copy of VS.net 2010 ultimate edition, are there a lot of major changes, cause i got 2 thick book for VB.net 2005..
When you've finished a program and you're trying to distribute it to the mass public. How is the best way to go about doing this? What sites would you post your program on and getting the word out that there is a new program on the block and it does xyz. This is directed to freeware so there wouldn't be any advertising.
Sorry for not explaining it very well the first time.
I would like to place the code below in a click event for a button to open a word file. I have added the document (group2.doc) to the Application folder of the target machine in my setup project. how do I write a dynamic file path that will open the file?
well I want it to look like this: [Textbox] [Browse] [Start] So you click browse, find the exe file, click ok(or something like that) and then click start I also want to make it so it saves the location of the last exe file it started, so you dont have to browse for it every time you use the program.
I'm sure there is an easy answer to this, and it may be "no," but is it possible to create an install file in VB Express 2010 and have that file deploy additional .exe files?
I developed a windows form program that calls fortan routines (in seperate .exe files) for different purposes. I would like to create an install file that deploys not only my VB program, but all of the supporting code.
Is this possible with VB Express 2010? I tried to search for threads about this, but didn't find any that explicitily answered this question.
I have one combobox, two buttons (Add and View) and listbox. When I click button Add text from combobox is added to text file. This is code for Add button:
i want to take a comma delimited text file and then select all unique records based on one of the fields in the text file. should i read the text file into a data table or just use a data reader?
Hi, i'm trying to use the treeview to display the text of a rtf (rich text file) file when an specific node if clicked.HomeOMGWOOTFor example, if i pick OMG, i want the text of lol.rtf to be displayed on a richtextbox. But somehow i just can't manage to get it... I know to import the text of a .txt file to a textbox, but using the treeview makes it more complicated.This is the code im using right now:
Private Sub TreeView1_NodeMouseClick(ByVal sender As Object, ByVal e As System.Windows.Forms.TreeNodeMouseClickEventArgs) Handles TreeView1.NodeMouseClick Select Case e.Node.Index Case 0
[code]....
Another thing is, that i can't import the *.rtf text into a richtextbox and i don't know why.
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.

Ok so I have a combo box that lists a set of names. What I want to do is match a selected name to a text file and read from it. The text file contains the same name and has grades listed below:
I want to create a text file or see if a text file exists when application starts. The problem I was having was after creating the text file, I tried to write to text file and got an error saying that another process was using it.
Dim test As String = My.Computer.FileSystem.SpecialDirectories.MyDocuments & " est1.txt" If System.IO.File.Exists(test) Then MsgBox("File Loaded") Else
[code]....
I looked up topics on filestream, but am unsure if this is how to use it. Is my code ok? Is there another way to create a text file?
I save data from datagridview to text file. I also load the same data from text file into datagridview for edit and update the same thing to text file. Let say this text file i called as Drill.txt. I have another text file called header.txt which need to match its value with the value of Drill.txt file then overwrite value from Drill.txt to header.txt. Now i want to make my Drill.txt in encrypted format to prevent anyone to open that file and modify out of program. They only can modify it through the program
i have 5 textboxes in a form. I have a streamwriter that writes all of their text to on text file like this:
Code: Dim xfile As String = Application.StartupPath & "/Set.txt" If File.Exists(xfile) = True Then Dim writex As StreamWriter = New StreamWriter(xfile)
[code]....
I was wondering how to get the text under the each number and place it in the corresponding textbox.
I am using a thread to call a process which is spliting a text file into various text file and folder using the system.io , now when calling the Textsplit() with thread on click of a button i am getting the error below , how to use thread and why this error occurs.
Cross-thread operation not valid: Control 'txtbox_destn' accessed from a thread other than the thread it was created on.
I am trying to ping a text file("C:/Domains.txt") which is a list of domains, then have the resulting IP address written to a different text file ("C:/IP_Addresses.txt"). And this action will be done with a Button_Click.
All I would like to do is remove one character from the line of the text file that I am reading, which is the first character and also prevent the program from crashing if no text file is present.Here is the code. Can anyone notice where I am going wrong? I thought the "if" statement would cover the crash but it didn't. Clueless, but sort of have an idea on the character removal.
Private Sub RadioButton_CheckedChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles RadioButton.CheckedChanged Dim fileReader As System.IO.StreamReader Dim lineRead As String If RadioButton.Checked Then
what would be the optimum code in VB2010 that check a file to determine:
1) is it a text file, and
2) if it is a text file, does it contain any non-ASCII characters
Note that LF, CR, and EOF would be expected, and should not be flagged. I can think of 3 - 4 ways to do it, but there may be a 'best' way in terms of simplicity and speed.
How would I create a "Save File". I am creating a launcher and need it to save the programs and different texts i have on the program to a save file. One side question: How do I do Links in VS?...HyperLinks that is.
