I am trying to insert data into my database but because i have relationships in the database, i can't enter data into one unless the other has been entered but i can't also do all that at the same time.This is the error i get: You cannot change values of this column because it is related to another table, what do i do and what is the next best option if i don't want to use "autonumber" but want to make sure i don't repeat numbers. How do i implement that?
I'm trying to do the very basic add "hello" to a button. The instructions tell you to click on the button the tutorials say the code that is supposed to show starts with "public class form1" but when I double click the button it seems to open the whole code of the template, not the button. (and no where in the code shows the "private sub button1_click")
One of the problems that I constantly see with Winforms applications is that the GUI thread is stuck while a long-running task is running or just plain stops refreshing (yes, I know - needs threading). Is there a code template/design pattern I can use when reacting to mouse clicks or button presses? Should there be a processing thread always running in the GUI app? Basically, how do I write a great Winforms Application that is easy to maintain and doesn't have any quirky refresh bugs?
if could modify the following code for me so that it save data row by row from a DataGridView into SQl Server. Currently, the code saves data from all rows at time instead of saving only the recently added data in a row or rows when the user clicks a button.[code]...
Changed thread type to QUESTION. I was then able to mark AS ANSWER the relevent post which now also immediately follows this post and so it is easier to find as suggested by forum user j2associates .

Im creating a noughts and crosses game, what I want to happen is for the user to choose either an X or a O from a combo box then click the button to try and win the game, now the game is just about finished, ive finished the design work and all the code is written.HoweverThere is one problem, the buttons are not behaving correctly, when I first load the game the first two button select a character and they shouldnt until a character is selected, also when I choose a character only the first two buttons work, if I press the new game button which resets all the fields then everything works fine.Below is the code I wrote for my combo box - human player is a form level variable as a string data type
I'm using devexpress aspxbutton, and I was wondering how can I prevent the user from clicking the button more then once..? basically it does an update/insert statement.
I need to visually moves the cursor using keyboard keys.
1) I need to get the mouse to where the button is
2) Simulate the mouse movement to the button from wherever it is
3) and simulate a button click.
Only after i select a button i can start drawing on my form. I have a code here, when i hold the Ctrl key and press the arrow keys, the mouse will start drawing straight lines. But what happen when i need to use controls like buttons, comboboxes etc.?
I want to be able to hit enter or return on the keyboard and then for the next button to automatically click. Once you're done typing in the value to a textbox you hit return and the next button clicks.
To prevent multiple clicks on button in VB6 I have add button.enabled=false in start procedure and button.enabled=true in end. But in Vb.Net all clicks are stored in memory and wher procedure is over - then it started again. You can see it in this example:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Button1.Enabled = False
