How do you check to see if a form is already loaded, ie if it is already loaded bring to the front else load the form.
View 3 RepliesI need a check that will see the location of the edge of the form. An example would be (for what I am trying to do) is, when a form is moved, the main form will get bigger depending which border and which way the second form is going.So basically I need some way to make Form1 get bigger if Form2 is near the left border or near the bottom border.
*I have a mini system for making it grow(LocationChanged) on the form I want it to work for.
*I also know about ".left" and ".top",
I have a form that has a large number of labels. Is there a way I can move the focus from label to label. After I move the focus I'll check if the name of the label has a certain string in it. If it does then I'll leave the focus at that label. If it doesn't I'll move the focus to the next label and check if that label name has the string in it. I just need to know how to move the focus from label to label. I was trying SelectNextControl without success. Maybe I can tab programmatically to the next label but I don't know how to do that.

View 1 RepliesI have a Parent form that loads a child form and I only want to allow one instance of the child form. I have this on the button to open the form. Stepping through the code with the debugger it "appears" to work OK when the form is open (I say appears because nothing changes) but when the form is closed it doesn't open as I would expect. What am I missing?

I want to pre-load a number of images from the web, so that I can display them in a form, and scroll through them without delay. It can be a large number, but i only need to pre-load perhaps 20, and then remove/add in advance, as I scroll through. The images will typically be .GIF or .PNG, of quite small size, <50kb. The link for any single image will look something like this: [URL]..and I will keep a list of all the links I need to access.
What "type" shall I use to store these images? And how do I make web requests to put the data into this type? I guess it will be more convenient to keep this as in-code list of some memorystream type (?) instead of saving them to disk and having to deal with file names and stuff..? Also, what type of control shall I use to display such images? Do I use a PictureBox?And if a memorystream is indeed the best choice, how do I make this show in the picturebox?

This is my problem.I have a field set up in MS Access to Boolean YES/NO, this field is populated when the user check a checkbox on a windows form. If the user check a checkbox, the value is written as checked in the data field (MS Access).The problem is when I search for the user information, I need the information from the Data base to populate(return) to the windows form. Example: If I enter a users phone number and the user data is present, the form gets populated with the information the user previously entered which was store in the database.Example: If the user selected checkbox1 and submits the form. When I search for the user info, the check box should check(populate) because the user had checked it on submit.Here is what I have done:

Visual Basic Project - Student Check In Form using an Access database backend This form needs to draw information from an Access database containg tables for STUDENT, INSTRUCTOR, and SECTION. These all need to have primary keys and ids. When (the user) clicks on the drop down box that displays all the sections:
{Table Tennis 1, Table Tennis 2, Table Tennis 3, Billiards 1, Billiards 2, Billiards 3}This should populate the listbox or datagrid from the STUDENT table with the Students that have the same SECTIONID as the SECTION selected in the drop down menu above.
After the Student list has been populated (the user) clicks on a student name in the listbox/datagrid and this inserts that student into the CHECKEDIN table that has a datagrid/listbox associated with it.
This is a great project to practice connecting a database to Visual Studio 2008 .net and playing with the data that has been pulled in. You could use SQL instead of Access.
