What I'm doing is adding files(music,videos, and pics) to a flowlayoutpanel. I just don't know how to save those controls made at runtime, this code is my import code.

When the user reopens the program it needs to load the button in the same spot. So far i have a streamreader reading the file in each line. There is a one sentence split by ",". Each of the three components are loaded into an array. how can i call the buttons it i am unsure of the name. Possible answer could include using sender, addhandler.

In the windows form designer, I added a StatusStrip control, made some changes to adding items and changed the names of the items to names I would recognize, for instance I changed "ToolStripStatusLabel3" to "lblMode". All was fine until I inadvertenly deleted the StatusStrip. Now when I add it back to the form and try to change the name I get an error saying that the name "lblMode" is already in use. And sure enough it is listed in the items of the properties window, but not dislayed anywhere.
I am not sure how to resolve this. I know there is a window, I think its called "Project Designer" or something similar that is code where controls get added but I CANNOT find this window to view the code.

View 2 RepliesI'm building a form with just a combo box in it that contains a list of other forms that I made. I want to program the combo box so that if a user opens it and clicks on "Web Browser", that form with the combo box will close and the web browser that I made will open. Another example is that if a user selects "Media Player" from that combo box, the form with the combo box will close and the media player that I made will open. How would I program the combo box to do this?
View 3 Replieswhen closing the form, checkchanges() is run in order to check if there is data changes..in checkchanges(), i compare data in database and form..if data in form is not same as in database, it consider data has been changed..thus, if there is changes, user will be promt to save data before close..the problem is, when my form is closing, the checkchanges() always show no changes, even when i made changes..this is because, when data is compared (between database and form), the form is already commit changes in database..that is why , when data is compared, it is actually compare the same value...
For example:
*when form load*
database: employee number = 1009
textbox: employee number = 1009

That is why checkchanges() always show no changes.because it commit changes to database before it made comparison..what should i do to prevent from commit changes when form is closing?
I have designed a complaints form for my work (free of charge just for my cv). I designed the form for the resolution 1280 x 1024. My problem is when a user with a smaller resolution say 800 x 600 uses it. The form will be out of sync with the screen as shown below (tested on my on computer). So I am wondering is there a way to test the screen size of the users computer then readjust the size of my controls according to the size of the screen. By the way all of my controls are anchored so that they stay in the same place.
