Retrieve A Value From A Second Form?
Apr 12, 2009
I'm teaching myself VB.Net.
Here is a problem I have recently come across. Say I have a main Form1 in my application. Form1 calls a second LoginForm which (like the name suggests) is a login window with username/password type fields. Expected behaviour is that LoginForm will capture login details and pass them back to Form1.
In my mind, I was thinking along the lines of a function call like 'doLogin' that would 'show' the LoginForm, capture the data entered, dispose of the form and return the login details (probably in some kind of bean). Somehow I don't see this as being possible
What I have currently is less elegant. LoginForm is shown by Form1 modally (i.e. showDialog); a 'me' reference is passed to the second window. After user input has been received on LoginForm, I set a value on Form1, then dispose.

I still cant think a way to get my database from the datagrid in form2 and display it on form3..my little program is like a schedule that you'll edit your students class hour,subject and teacher.. then after that when you view your schedule.. you'll see only what subject you'll be at in that student data schedule...i've tried dbgrid.columns(n).text = label1.caption, but i found out that it'll copy the data but only those on the 1st row >.<. ill upload my program here for you guys to have a hint what program exactly im making on.
Here's the link :[URL]

Its suppose to save the stuff written in the texbox for example
I have to input 255 students Name, address, age and Birthdays and save them all and then try to find all of the info stored by entering the Name.
Also i have to generate a student Id not just giving a Id to them so for example if the first student i enter his ID # should be 1 and so on as i enter the name

I have successfully added textboxes to a form at runtime. I have also succesfully added an event handler to these same textboxes. What I'm having trouble understanding is how to refer to these textboxes programmatically after they have been added. Specifically, how do I;
1) Retrieve user data entered in those textboxes without an event handler
2) Find a specific one of those textboxex later (is looping thru all controls of type "textbox" the only way)?
purpose of find is so that I can set the value of the corresponding textbox programatically, based on some criteria Here is the code (all within in a for loop, where intvararycount is incrementing to a set limit) I have used to add the Textboxes to a Panel on a Form;

Not sure how to word this right as I've never done it before. Also not sure which language I should code it in..
How would I go about getting a value from an exe if I already know what address it's located at?
For example..in the app I'm making that calculates the current xp per hour, I need to be able to retrieve the total xp on my char from the game exe. I already know that the xp is located at 0080B910 and can see it with my debugger.

I have a combobox (dropdownstyle=dropdownlist) with 4 items in it (defined in design time). The items are the following:
1;0,1;0,01;0,001
I read a row from a database (which contains a field with one of the 4 items) and I want to display this value in the combobox.
I use this method:
cmbtizedesh.SelectedIndex = cmbtizedesh.FindStringExact(pgreader(4))
But it works only, when the field value is 0,001. In any other cases the combobox value remains empty (the result of the FindStringExact function is -1). The pgreader is a NpgsqlDataReader object and retrieves the right values.
