VS 2010 : Save Image To Datatable?
May 11, 2012
I have picturebox that the user can import an image, and then save it to the datatable. I can save it with no problem, and the image, which is a logo, will populate onto my crystal reports pages.My issue, is that I want the logo to automatically load into the picturebox when the user opens my settings form. How can I do the opposite of the following:
'set the company datatable for sub
Dim borrowersrow As PlannerFilesDataSet.CompanytableRow
'use only the first row
[code]....

I want to save a datatable to the app.config file (My.Settings) and what i have understand is that you can use the Datatable.WriteXML to convert it to XML and then save that string to the settings.
But how do i rebuild it from the xml? Do i have to create my own code to do that or is there a method?

I have an application that users will save a list of clients to a database. The extension on the database is .sdk, and I think is some kind of sql database. The user can save rows and add rows to maintain a client list, but when I release an update, I have to install it without the database file. If I install with the database file, then their current client database is replaced with a new blank database.
my issue is that I need to add columns to tables in their existing database without overwriting their current rows. For example, i have columns for client name, address, and phone number currently. On my next update, I want the user to be able to save client birthdays. Here is what I have:

I have a DataTable (comprising of three columns) created at runtime & populated by the users selections in other parts of the app. The DataTable is required as I need to manipulate the users data before graphing it, etc.I now need to save the DataTable (& associated data) to an Access DataBase so that I have a record of what the users data was.
Everything works fine apart from the saving of the DataTable bit........
I've managed to get the following working :-
For Each row As DataRow In ResponseTable.Rows

On top of the image inside the picturebox I've added labels on different locations(the labels are added on run-time using PictureBox1.Controls.Add etc). I want to save the contents as well as the image inside the picturebox.

I am "weeks new" to visual basic 2008 but I was hoping that someone might tell me how I can open an image in whatever type of "visible" graphics window (always positioned at: x=0 y=0); move to some "definable position" of interest x=(n) y=(n); change the brightness of that "individual pixel" by some "definable means of measure" from its original state; and save the new image as a separate image file?

I hoping to find a current and simple way to do this. I'm using VWD Express 2008 and SQL Express 2008.I'm able to get the client's path to the image file using an asp:FileUpload control on the web form.
How do I upload the client's image file and display it in the web form's image control?How do I save it to the sqlserver? The image table is already set up with a "Image" data type column. Can the image be saved to the database as simply as other data types?

I'm a VB beginner.I've been playing with Graphics.DrawString by watermarking a picture with a text string. The picture below to the left comes from PictureBox with a text string drawn with Graphics.DrawString. The font style used is Arial 48 points, regular, I think. The picture in PictureBox shows just as I configure. Great... The resolution of the original Terri Hatcher picture is 300 dpi (300 x 300). Exporting this picture with Graphics.DrawString, I get the picture below to the right. The text string appears a lot bigger than previously shown in PictureBox. It turns out that the text size varies, depending on the resolution of the original picture. That's kind of odd. I develop several graphics applications in a different environment and have never seen this sort of graphics.drawstring thing. Anyway,
my sample application seems to draw a text string at an image resolution of

I work with windows forms and on the form I have a DataGridView. This gridView I fill with a DataTable dt. The dt I fill with OdbcDataAdapter. For save the changes I use adaper.Update(dt) on Event Handler gridView_RowLeave. The problem is that dt doesn't have last changes of gridView. For exemple if I modify some data in one row or add a new row with data when I leave that row the method dt.GetChages() return false and I must leave more that 1 row for dt.GetChanges() return true.

A year ago I saw a beautiful simple code that gets a data table and saves it in an excel file. The trick was to use the web library (something with http) and I'm almost sure it was a stream. I find a lot of code with response but I can't make it work in a win-form environment. There is also a cell by cell code - not interested -too slow. I want to paste it as a range or something close.
