Open File With File Name In Tabcontrol's Tabpage1 Name?
May 11, 2009
i have this to open a file:
Dim FILE_NAME As String = "C:Documents and SettingsOwnerDesktop esting.html"
Dim objReader As New System.IO.StreamReader(FILE_NAME)
RichTextBox1.Text = objReader.ReadToEnd
objReader.Close()
what line of code am i missing to add the file name without the path in the tabcontrol's tabpage1, so instead of saying tabpage1 it would have my filename that i opened..
so much work to do and so many choices to choose from...

I have 2 questions.
1- Let's I have a form with a TabControle and 2 tabpages, is it possible to set the tabpages so that if i go from tabpage1 to tabpage2 that all data on tabpage1 gets reseted. The same thing if I go from tabpage2 to tabpage1 that tabpage2 is reseted. Also if I press on tabpage1 or 2 that the form changes to a certain height.
2- On the same form I created a button to open a new form. This new form is a notepad look a like. What I want is that the moment I open the second form that al the input from form one is showed on form 2. So that I can save it or print it.

Trying to write my program in vb.net 2010. I have read my 2 books and have been playing with the code a bit. Got streamreader and writer and My Namespace understood as far as text files go. Now I'm trying to get all my textboxes in tabcontrol tabpage1 to be cleared of text thru the For Each loop.
I've tried various ways and keep getting invalidcastexception error. I even changed the tabcontrol and tabpage modifiers to public. That did not work either.
[CODE]:....................
I thought the code would not only clear all textboxes on tabpage1 but on all the tabpages. The help tells me that "When casting from a number, the value must be a number less than infinity and to make sure the source type is convertible to the destination type. I have three tabpages and that is definitly less than infinity. The source type and destination type puzzle me a bit.
Here is what I got using intellisense, however it not only clears the textboxes of text on tabpage1, but it clears the labels and buttons of text too so it is not a perfect solution.

Years ago when coding with VB6 and earlier, I used a file open command to create, read, and write a file that made it easy to store useful information.I believe it was binary and you wrote/read the data to a specific line in the file. When you opened the file with something like notepad, it just showed random ascii chars. When I needed a line of data, I could specify what line to load it from.

I've gone through about 16 hours and two packs of cigarettes trying to figure this out. First a little background. I was using 6.0 up until 2004 when I went to prison. I'm out now, and trying to relearn the trade, using VS 2005. I'm currently porting some 6.0 code from another project, SpyCast Webcam Studio, into VB 8.0. It's disheartening, to say the least. None of the old built-in subs/functions work anymore, so I have to scour the forums to relearn each and every function.The section I'm doing now takes a snapshot from the webcam (Video API --> PictureBox --> Save as Jpeg), then upens the file to upload it to the server via HTTP POST. I've been using this code in SpyCast for years with no trouble, but I spent many hours trying to piece together the right code to open the binary file to read its contents. I pieced together two methods I found around the forums, one using FileStream() though the code I found wasn't for binary files, even though it said it was, so that code doesn't really work. Method two uses Microsoft.VisualBasic.FileOpen() and works better.
Here's the kicker. By the time I run through the rest of the rigamarole of uploading the file, by the time I read it on the webserver, it's *slightly* corrupted. It's a valid Jpeg, no errors, but the picture looks like when I use to watch the Playboy Channel when I was a kid scrambled with weird colors and whatnot. [code] Each "chunk" is basically one "line" of the file. It looks like a single LineInput() return is the text between two carriage returns. Am I correct? I tested this with a flat text file, and it looks true. However, That one input line returns the text or data with the carriage returns *stripped*! ***?!? =( Fine, I have no problem adding my own vbCrLf to each LineInput(), if I were opening text. but this's binary. A character could be Chr(10) or Chr(13), both of which are removed from the original file contents.So I could very well need to use something other than LineInput(), but I haven't found any other examples on the web using this method.

I need a code for the open file dialog that if a file is not supported then a message box appears stating the error. This is my open file dialog code. [code] The message box pops up like it is suppose to, when you click ok the open file comes back up like it is suppose to. When you put in the correct file the message box comes back up again. Also the message pops up even if the correct file is put in the open file. but if you close the file dialog the image is where it is suppose to be.I believe the code for the public sub wrongfile is what is the problem. can some one look it over and let me know what changes are needed.

It is saved on my desktop for easy access.I can close the program. I can click the solution to open it right back up, no problems.I then zip my file (also to the desktop)
My problem: I moved the original file (Project A) to another folder and extracted the unzipped Project A onto the desktop. When I open the new Project A's solution file, nothing happens besides VB starting up. It doesn't show me anything.

I need to open an excel file from vb.net and then search it for specific data. I then need to take those data and insert them into text boxes on a form that i have created. This is all controlled by a button click. I already have some code that will open a file dialog box and let me navigate to the correct file, but I am having trouble with the search portion. I have tried the Find function but I am not sure of the proper syntax. I am using Visual Studio 2008 and Excel 2003.

code snippet that would allow a progress bar to track the input of a text file? Normally I would not bother with this, but the text files are > 10,000 lines long, which is noticable even on a fast machine. The number of lines is variable, so I would assume that one would not use a fixed value to calculate when the progress bar goes 100%.

Is there a better way of finding the path of a file that was opened with the open file dialogue? This is what I did. It works, but it seems like there should be a way to get the path through one of the open dialogue options.
Code:
'm_PicSource = OpenFileDialog1.FileName
'm_PicSource is a global var
Dim strCnt As Integer = m_PicSource.Length - 1

what im trying to do and what i have done so far is probably a little backwards not sure sure how to id it any other way.when the user generates an error because a particular file doenst exist ive got my dialoge box to generate an .txt file for each file it errors on, so that the administrator can check and update missing files as an when - shouldnt be many files missing in the first place, should just be new product ranges or item just launched.what im stuck on is:
1. is there a better way
2. how do i open a .txt file and add the extra lines to it, so i re use the file but keeping the previous data.

I am trying to build a simple AutoUpdate application using VB.NET. It was quite simple. That is, I put the newest ZIP file in my hosting site, and then download it using WebClient.DownloadFileAsync. After it get downloaded, I extract it using [URL]
But each time I run the unzip.exe using Process.start, Windows 7 always show Open File Security.
Is it possible for VB.NET to bypass such security restriction?
Btw, this is my code of using WebClient.DownloadFileAsync, in case any one google about it and landed on this page :
Public Class AutoUpdate
Dim installationFolder As String = "C:Program Filesxyzabc"
Dim updateFileNameTarget As String
Private Sub btnStartUpdte_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnStartUpdte.Click
