PictureBox - Image: Select The Path To A Local Folder That Is Within The Application And Get An Image From It?
Sep 15, 2010I have a Picturebox and a two Buttons on my Form. On click of one of the buttons I want to change the image in the picture box at runtime.
This works fine when I give the location of the image (the full path ) on my computer - but then of course it will not work if I use the solution on a different computer .
So I have made a folder named "Pics" inside my application and added two images into it.
How do I get to this local folder in the following code?
Picturebox1.image = system.drawing.image.fromfile (??? )
instead of the usual,
Picturebox1.image = system.drawing.image.fromfile ("C:UsersMyName My PicturesMyPicture.jpg" )

View 2 RepliesSelect A Line Of Text In A RichTextBox?
Jun 13, 2010I have a RichTextBox in a VB2008 Windows Form application. The RichTextBox has tabs set at 250 and 400. The following code snippet is used to populate the RichTextBox using the result of a LINQ query.
rtbData.AppendText(String.Format("{0}.
{4}{1}. {4}{2}{3}", strTitle, strAuthor, strBook, ControlChars.CrLf, ControlChars.Tab))
I've noticed that most of the time it takes several mouse clicks to highlight a desired line of text in the RichTextBox. Is there some code that will allow selecting the entire line that a user clicks on? The length each line in the RichTextBox is not the same.
Select All In Textbox During Runtime?
Oct 15, 2009The textbox that I create in vb.net does not let me select all the text using the common keystroke control + a at runtime. The textbox is able to detect all other keystroke combinations at runtime, such as control + c, control + v for cut and paste, but it does nothing for when the keystroke control + a is pressed. Is this something that vb.net textboxes do not detect and therefore I would have to program manually by having the program detect keystrokes and then have the program select the text using the code TextBox1.SelectAll() ?

View 4 RepliesControl Arrays - Combobox Select A Datasource At Runtime
Jul 26, 2010I have a form where I have to use control arrays to create a multiple input form i.e. rather than processing one transaction at a time up to 16 transactions must be processed. The following really havent given me much problems at this moment labels and textboxes. I use a for construct to create all the controls including a combobox. This is where my question comes in this form combobox has to be linked to a table in a database. But furthermore and this is where it gets complicated for me anyway each seperate combobox must move independly if i select row 5 in the table in combobox 4 combobox 5 which is havent touched should still be on row 1. How do I accomplish this. I'm using a webservice. I have tried passing a loaded dataset . The code that loaded the dataset is as follows
Dim DSInfo As New Project1.localhost4.AccInfo
DSInfo.Credentials = System.Net.CredentialCache.DefaultCredentials
InformationData.Merge(DSInfo.GetBusinessJournals)
[Code].....
this code doesnt however provide a link to the table equallly creating a dataset in the combobox method ,loading it and then setting it as datasource also provides no link. I know i'm missing something.

I can accomplish it if I already know the image and path etc. and do it through code, but that will not allow someone to simply click an image, copy, and paste it into the rtb.
