View 2 RepliesI have already done the creation of button and the dragging of button at runtime already.But now i need to know how do i save the last dragged button on the form and also detect the name of the last clicked button.so lets say i now drag a button to coordinates 25,254. so when i exit the form and the next time i launch it, the button will still be at 25,254. and this one will go on for the number of button i created like 100. so when i launch the form the 100 button will be at the exact position where i last saved them.the second part is lets say i created button1 and button2 on the form in runtime. so when i clicked the first button, it should display button1. and if i clicked on button 2, it should say button2. same goes for like 100buttons.

Form 1:

I have a web application and on page is an update page to update some profile information. Below is the code I am using to update the table. But I think it is wrong. Does anything stick out? The connection string works cause it is used to read the database to get the profile information, I just removed it due to it containing password/login info for the db.player is the class of properties that contains player information and ds is the dataset, but I would like to update the database itself online.

I have numerous buttons on a form, one each to select a playing card (52 buttons). When the Card(button) is selected I want to highlight it by changing the border from black to Red, then if reclicked from change back from red to black, easy enough (if then else). So that I do not have to copy this code 52 times I wanted to create a module as follows:
Sub ChangeButtonBorderColor(ByRef ButtonName)
If (Equals(ButtonName.BorderBrush, Brushes.Red)) Then
ButtonName.BorderBrush = Brushes.Black

I have three tables Tasks, Notes & CallTypes Each item in Tasks and Notes has a relationship to CallTypes and my form edits work fine. However: Notes only belong to tasks, and when i update the note record we will need to change the CallType for the Task as well as for the Note and they could both be different.
I have the Notes working fine, but i cannot update the tasks. I have created a databindng on to a form from the datasources window. All the notes fields are ok and are working I then add the calltype field from the tasks, draged from the data sources window (i dont want all of the tasks fields, just the calltype).
The code does not through up errors, but when i save the form it only updates the notes and not the tasks.

Using; - vb2008 Express, data on ACCESS 2003, objective; - to update a separate table not on the original query.From what i have gathered i need to add a second table adapter to make the changes to a related field in another table. Since i already have the 1st table adapter the second does not appear as easy as the second (dragn the data set over).
So i suppose i need to create the second table adapters programmatically? [URL]..I see that because they are not nested they need to each be declared.. right? If so that is where my issue lies. I'm having a problem with how to declare them both now that there must be two.

how to get the form to save some data, but the problem is I only know how to get it to save as the body. since the main parts of the program are third party, but here is the code I'm using to save data.

How can I do this, this what I got so far.

My btndisplay cost works, but my btnexitprogram does not close the application when clicked. I've ensured the button is correctly named and enabled. But when I click it does not close out, I use this simple code in other programs and it works.
I have a calculate button that, if clicked more than once adds the total of what I previously had to the new total as I am using a loop. I was thinking that I could get around this by only allowing the button to be clicked once, and if the user attempts to do this more than once a messagebox will appear saying that you can only calculate the price once and the form resets but i can't seem to get any code working.
