I just wondered if it is possible to save multiple text boxes as one file.Currently I:
a ) haven't woked out how to save a TextBox atall and have had to use Rich Text Boxes for this purpose and have used: RichTextBox1.SaveFile("Something.txt")
b ) Haven't worked out how to save/open files as one file. I have had somebody suggest to me using Arrays but I do not know what this meens
I use the code below to save a textfile to a directory that should work like this[code]...
View 1 RepliesI've made a browser project and beyond making it a default browser, I am having a problem with the Favorites feature TreeView control saving, loading and repopulating it with the users data. It's tough finding the correct code as there are so many variations of this control in various languages, but I did find sample code for loading and populating the TreeView with a text file using tabs to signify the node structure in VB.Net. (Most others I have found are VB6 or some other variation.)

Everytime I go to save my listbox to a file (the same text file each time) I'm trying to overwrite the file (old list) with new file (new list), but it just adds my current list to the end of the list that was already in the text file to begin with..

View 2 Replieswhen you have a textbox and you save the contents to a file : My.Computer.FileSystem.WriteAllText(SaveFileDialog1.FileName, TextBox1.Text, False, System.Text.Encoding.ASCII) and you open the file in notepad, you will see instead of multiple lines one long line and where the vbNewLine should be, a small square symbol.
the simple reason is: even if you write a vbNewLine or vbCrLf to your textbox, it will be reduced to vbLf so when writing the textbox.text to a textfile it only writes the vbLf where you would like to have a vbCrLf
so all you have to do is replace the vbLf with vbNewLine :
My.Computer.FileSystem.WriteAllText(SaveFileDialog1.FileName, Replace(TextBox1.Text, vbLf, vbNewLine), False, System.Text.Encoding.ASCII)
I cannot figure out how display the data from my array in the listbox using a For Next loop.I'm not even sure if the data from the textbox is even getting stored into the array. Here is what I have so far:

I am looking for ways to retrieve data from textfile and save it into access database. Currently, I am doing a attendance record project. I need to save the attendance record which is given in a text file to the database. The version of VB i using is VB 2008.
The content of the text file look like this:
E010,2009/06,06/29/2009 7:44:45AM,06/29/2009 15:00:55PM,JUR
E022,2009/06,06/29/2009 7:44:45AM,06/29/2009 15:00:55PM,JUR

I tried to create a class and store the record but it just don't work.
Dim days_in_clc_month(10) As Integer
days_in_clc_month(0) = 30
days_in_clc_month(1) = 29
days_in_clc_month(2) = 30

i just need to get this block of codes out, and put it in a textfile. and my program will run without seeing it, because it's all saved in the textfile.
I got a question. I have a textfile name membership.txt and using vb2008. However my code found error when try to grab the data to an array. I use delimiter "|" to separate between each data in line to save in specific column in database.

I have a textfile I need to open and I need to put each line into the array. What is the simplest way to add the elements/each line's data into the array while increasing the array as it reads each line? This is blowing my mind right now..I thought about using a counter and then redim-ing the array (while preserving of course).
View 3 RepliesI've got a csv text file "test.txt" in the following format with one record per line in the following format: Builder,Bob,B,99HappyStreet,Springtime,4
I've read them into an array and in design use the first two to populate a listbox and then use a selected index to fill text boxes and some list boxes.
ex. TextBox_FirstName.Text = Employees(ListBoxMain.SelectedIndex).FirstName
How do I write the changes made in the text fields back to the position in the file where it was? It has me stumped although I'm sure there is a SelectedIndex option that can work.
I've considered having all the new/changed data saved as a new record and then just deleting the 'old' entry but my delete code gives me a selectedindex-1 index out of range exception error that I'm working on as well. I am sure both problems are related.[cod]e...
How would you store records in a textfile to an array, so you could display it on a series of textbox(ie. firstname, lastname employee number etc.)

Now I want that presented in the listbox with the semicolon and it should be aligned per column so that the numbers, the names, the prices and the quantity are exactly aligned per column.If I read the file like this:
[code]...
Then the semicolon is not presented in the listbox and I don't have any alignment per column. As the names of the woods are not equally long the prices and the quantity are not aligned directly below each other...
My questions are:
1) How to add the semicolon in the listbox as seperator of the columns
2) How to align the 4 columns in the listbox (as I have an array Item(3) )
Later on I need to be able to change the quantity (last column) from 0 to > 0 (that's why I have to use an array)
I'm using VB 2008, and I have created a Ribbon (Visual Designer) Add-In for excel 2007.When the user clicks a "Save" button, that was created at design time, this buttons click event prompts the user for the new file name...then saves the workbook.then uses the new file name as the label for a dynamically created button that is placed in Menu1, on Ribbon1...all of this works just fine.The problem is, this dynamically created button in Menu1 disappears when excel is restarted. So, I setup user scope settings in an attempt to save these dynamically created buttons.The settings properties are as follows:
Name = RibbonSettings
Type = Microsoft.Office.Tools.Ribbon.RibbonMenu
Scope = User[code]....
The problem is, this seems to lock Menu1 and the dynamically created button never gets added to Menu1. Without this, the button is added to Menu1 just fine, but disappears upon restart.How can I save these dynamically created buttons in Menu1 on Ribbon1?
I am trying to create a textfile and write some lines into the textfile. However, the code that i am using can only write when the textfile is already created in the directory.
For this case, can i actually allow my script to search if a textfile is being created, if not create a textfile ???

View 2 RepliesI want to compare two array and save the miss match character into 3rd array.
View 1 RepliesI'm working on a program that has to get a set of images and then scan them to find pixels that match colors in an color array. Anyway I think I got everything working but how to load the images in as bitmaps. See the images are dynamic, they change there filenames so I can't call them with a static call like Dim bmp2 As New Bitmap("c:button.gif").
So I am using a loop to feed the images into an array for bitmap but thats not working, anyway that I can do this as, right now the program gets all the filenames for the images from a text file that is sent in to us. All I need to do is have the program check each image for pixels that match our color list. But I cant get the images into the bitmap array.

A project requires to allocate a varying number of byte arrays (buffers).
It would be ideal if the following definition would be possible:
Dim ArrayOfBuffers() as buffer(10000) as Byte
The byte arrays must be ordered sequentially because they have to be written to a file by efficient procedures destinationFile.Write(ArrayOfBuffer(3),1000,1000)
The number of buffers will change during program execution sometimes. Therefore it would be nice to be able to do a ReDim on the data structure when needed.
