Forms :: How To Let Method Know Which Form Is Getting It's Buttons Pushed
Jan 21, 2010
In design mode, I have 2 forms, Main and Profile. Both have many controls on them.When executed, the Profile form is duplicated 4 times and named Profile1 through 4. Among the controls on these forms are 3 buttons that copy the selections from the other 3 forms to the one that had the button pressed.How do I accomplish this? I don't understand how to let the method know which form is getting it's buttons pushed so it knows what form to copy...

I am making a simple program. This program is maximized as soon as it opens the problem is I made some buttons and labels and set the form Windowstate to Maximized so that it will maximized as soon as the program is run; now when I run the program it is maximized but the buttons and labels are not in the same place I put, for example I put a button on the bottom right corner when the program is run it appears in the fare left ( I post 2 pic ) Clipboard02.jpgClipboard01.jpg

I have a simple login field, which works fine with the exception of one quirk. The form is set up with the tab order to go to the UserID first and the Password text box second. This works fine when the form is used the first time, but when the form is used the second time the focus in placed in the Password field. If the form is used a third time, focus is moved the OK button, that is each time moves to the next tab order. I even tried to set the focus in the Load event as in Me.txtUserID.Focus(), but this doesn't change the behavior. Again, I should note that I close the form and not hide the form.

I want a string and a listbox, both which are in a form to be modified by an instance of a class method. Should (could I):
1. Pass the entire form to the class method as parameter.
2. Pass the listbox and the string to the method as parameters.
What's the best approach to get access and modify this string and listbox on the form.

I have 7 Windows forms.The order of the forms is defined within a configuration file.I want to place buttons on each form that will show the next available options.The Next button will move the next form in the list.The Back button will move to the previous form in the list. The Finish button will execute the final piece of code.The Cancel button will exit the application.If the user is on the first form, then there is no Back button.If the user is on the last form, then there is no Next button, but there is a Finish button.
Example 1:
Form1 - Next, Cancel
Form3 - Next, Back, Cancel[code]....

I've run into a bit of a problem.. I am unsure as to how many people know how "IRC" Servers work here but basically, i'll explain. We are re-creating an IRC Client we made for our Chat site in VB.NET originally vb6. We have serveral different forms but the main problme we are having at the moment is FrmMain is where you login to the servers, it grabs your data from our MySQL database such as "Nick, Gender, Font" etc. Then proceeds with connection to IRC server on Raw 001 we know the connection to the IRC server has been established... so therefore we open up FrmAuth which in this case they can see roomlist etc. We are unable to get FrmAuth to load probably.
We originally had this working opening up FrmAuth before the connection to IRC server has been established.. This really is no good for us causes alot of errors etc. So when we use just simply "me.show()" the form loads but freezes we tried doing Me.Invoke(New Del(AddressOf me.show))
however, this didnt work in which I assume that is because the "FrmAuth" hasn't yet loaded the GUI thread therefore there is no Thread to invoke so we tried FrmMain.Invoke(New Del(AddressOf me.show))
This didn't work either i assume you cannot access another forms Invoke method?
we are receiving the error A first chance exception of type.'System.InvalidOperationException' occurred in System.Windows.Forms.dll which i assume has something to do with it but not quite sure..
So my question comes down to the fact of, how do we open up FrmAuth without it freezing? Is there a way to access the invoke method on another form?

i know is there any simpler ways of coding to enable the user to drag and drop button and this button will toggle the background color when the condition is true. So which means to say i need to know where can i place the main program code in the code block.There will also be a provision for the user to delete the button control at runtime.

I need a listbox to be hidden. I need the listbox to display when a button is pushed. I am not sure how to code this. Also, do I need to have Visible for the listbox changed to false to hide the listbox until the button is pushed?

I'm just starting to use vb .net (using 2008 express edition) and I want to make a menu for my program that will be like a sidebar that when you click one of the options, a few sub-options will fold out that will push the main options below downwards - and then the sub-options will disappear and the options will go back into place when something else is selected.I am not sure exactly where to start in terms of making those options get pushed down/come back up..

I am working on this app and decided to add a listbox to the form since a listbox can contain objects. The objects I decided to add are buttons. When I launch my app. I see the listbox and what appears to be where the buttons are but no text is being displayed. Maybe I am missing the point of the listbox. Can I have buttons in the listbox and have the text display for the bottons?

I have a button in my windows form using vb.net when I actually clicked the button something happen then when I press any keys like enter or space, it focuses on the button since it was clicked and the codes in my button is the one that is executing rather than the codes in my enter or space key. I think it means that the button is being pressed when I hit spacebar and enter because there is a blue border in the button. When I click a button the focus remains on the button. I don't know how to remove that.

Firstly though, I'll have to mention that I'm a relative newcomer to vb.net and don't really know that much about advanced functions.I have my main form which dynamically generates 15 buttons.
Each of these buttons will need to open another form, depending on which form has been assigned to that button in a config file (the config file isn't yet done, as I want to get it working simply by hardcoding the name of the forms for the time being)
The way I have it in my head is that I would assign the form name that needs to be open to the name of the button, if that makes sense....However, I have absolutely no clue how to do it, I've tried a couple of things but to no avail.
Here's my code, and I have no problem changing any part of it if it will help things along, this is just the only way I know how to create dynamic buttons.[CODE...]

I have a basic math test program, and 2 forms to allow the user to choose which function to test on.
The first form has a list of radio buttons with the 4 basic math functions and a button to load the next form.The second form contains this code on Load..
[Code]...
frmOptions has 4 radio buttons, addition is default chosen.After selecting one, the user clicks a button to open frmTest.The above code runs upon first load to change a label to reflect what was chosen on frmOption above.
On step 3, the label on frmTest that is supposed to be changed based on the Checked radio button from frmOption never changes. It doesn't even change on the first load of the form, so I think something is wrong with the Checked property of the radio buttons.

When you complete various feats in my program, on a form called "User Details" there is a label with the text that says "Complete" only when you have completed a particular game. There is a save button, and a load button, all on different forms. How could I make a save and load feature? One that saves the fact you've completed certain games - and then when you press load after exiting and reentering the program, the Complete text will reappear.

I have a piece of software with two tabs, inside each tab there are buttons (the user can add the buttons when they want). when tab1 is full tab2 should start to fill. I currently know how many buttons fit on the screen so I just say something like if buttons > 150 then start to populate tab 2 The problem i have now though is if the resolution is changed then a different amount of buttons can be displayed. so if I put my screen to 1280x720 some buttons are left of. I was thinking of detecting the resolution and then using different cases for different resolutions but this seems very inefficient im wondering if there is a different way?
