this is the second time I have had the same problem come up so maybe some of you have had the same issue. I have a form that has only a text box a list box and a button. The list box is loaded with part numbers from a database, the text box is used to search for a part number and the button is to accept the selected part and close the form.

I am a bit stuck with coding my save button and combobox.My entire form is ready, database is linked.All fields from DB are linked to their textboxes on the form.But i just ran into a big wall which i cant seem to break down.My save button, which is used to save the content from all the textboxes on the form to the access database refuses to work.The other this is, i want to use a combobox on my form to view the already saved entries in the access database.I think a combobox works for that, but i am not exactly sure how to pull that one off.

For exercise 1 I have created the form with a button and two text boxes, but cannot work out the code I need to move text between the two boxes.

View 14 RepliesI want to achieve the following:
The user drags text from any open window not related to my application ( like firefox or word, for example) onto button1 on form1 in my application. when he/she does that, a new form (called form2 that contains a richtextbox) will open and the dragged text is directly copied (or inserted) into the richtextbox of the new form. button1 has allowdrop set to true. Beyond that I don't know how to proceed.
I tried:
e.effects = DragDropEffects.Copy
But it seems it is not enough.
I have a form with a text box and a form with a list box. I would like to be able to push a button on the form with the text box and have it be added to a list box.

I dynamically create buttons on a form and use the button text as ids so that I can pass that to an SQL query to pull saved data about that button when necessary, but I also use an image over buttons that have information saved about them. What I need to know is how do I keep the text on the button from appearing when there is an image assigned to that button? By default vb.net shows both the text and the image and no TextImageRelation values allow for the image to take precedence. I tried changing the text color to transparent, but the outline of the text is still visible through the image. Is there anyway to keep the text value as it is but just show the image on the button?
View 2 RepliesI am doing form validation in VB, I validate the text field data by using txtName_LostFocus function, and on wrong input I used txtName.Focus(). It works well for me. But problem is that as for as, user does not input valid text, my EXIT button also does not works.
View 1 RepliesI have a 'DataGrid' usercontrol on my simple little form and I press a button that opens a text file and populates the DataGrid like so,
A B C
1 2 3
3 4 4
3 1 3
Where A, B, and C are my column headers.
I also have a 'ListBox' on the form. What I would like to do is, allow the user to select one, two, or three rows (or all) in the datagrid, and press a button that will move the data from selected rows into my listbox (each row its own string in the list box).
I can populate the datagrib easy enough, but don't know how to access the cell data individually?

I tried to update the button text on a form from a backgroundworker.do_work event, and it failed, with the usual cross-thread exception message.However, by pure chance, I also tried to update text in a system.windows.form.toolstripstatuslabel also from this backgroundworker.do_work event, and it DOES work. Question: why is this? Is it perhaps because theres some kind of implicit shared behaviour with system.windows.form.toolstripstatuslabel?

I have a form in VB.net. When the applications runs it populates the data on a datagrid from the database. Then I have an export to excel button which when clicked creates a spreadsheet and dumps all the data in it. Nice!!!Now, what I want to do is have another button to auto email the work to my Boss. The work should be presented to him in a spreadsheet form, therefore I reckon after the export will be ideal or any ideas will be handy
