View 4 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.

in my form i have 4 textboxes and i want all not to be empty while saving the data.I have put condition in save button,when user presses the save button to save data, to check all the textboxes not to be empty. My question is that, i want to focus to that particular textbox which is empty during saving the data.
For example: i have txt1,txt2,txt3,txt4 as textboxes in the form if txt1 is empty while saving, the focus should switch to txt1 rather user himself have to go there.
In my Project I have a Dialog Box (MonkeyList), a Database(MonkeyList.sdf), and DataGridView1. DataGridView1 is on the MonkeyList DialogBox. I want to save changes to the table when OK_Button is clicked.

Let's say I have ten rows on a data grid and I have changed data of three rows.
I am trying to save data by Linq for those three rows, but I am not sure how it is possible to save them.
I can do it by looping whole rows by checking each row for any change.
Is there any smarter way rather than looping by code, such as For Next.
I have three tables under one database. I'm using the built-in Navigator control for now until I get this figured out, but I'm using a button command instead of the built in navigator button. I need the "Save" button to save the data in the text fill boxes to save to the corisponding table. I used the drag and drop option to drop rows from each table to the form. See code:

View 5 RepliesI'm trying to create a Library System in VB 2010 which is connected to a 2007 MS Access Database manually. I was successful to create a "Search" button where it displays content from the database based on the user's entries on several text boxes.
The result is shown on a Data Grid which I set to allow Editing on it. My problem now is I can't find a way to create an "Edit" button. My idea is basically allow the user to search, let the result be shown on the data grid, edit the data grid, and click the Edit button to save the updated records back to the database.
My question is it possible to create such button? Here is the code that I use to connect to the data base for the Search button.

View 1 RepliesMy system still show the "record has been added" and save/insert the data even if i chose the "no" button. I think I miss something on our codes. Should I add something?
Here's the scenario: If "Yes" (button) will be clicked, it'll save the data and clear the fields. If "no" (button), it'll clear the fields and shouldn't save anything.
Here are the codes:
Private Sub btnsave_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnsave.Click
If newname.Text = "" Or newaddress.Text = "" Then
MsgBox("Please fill-up all the requirements.", vbExclamation, "*** System")

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.
Private Sub Initialize()
' cmbLabel shows group(student) level
cmbLabel.DataSource = _schedule.DataStorage.LabelStorage.Labels
[Code]....
Since I have them all saving to the "body", whatever the last box is in the code is what shows for all three once I click save.
I use VB 2008. I want to check that text boxes have correct data but not at key pressed key down event. I want to check when user fill the form if all have correct data then insert into database otherwise get focus of specifiq textbox which have wrong data. I see many examples but all is applied on keydown keypress etc events. I just need a class i send Textbox as object in that which return true or false. I need one method in that class which check only numbers with decimal point and limit decimal places to 4 digit.e.g 12345.9876 and other method check A to Z and a to z with some special charecters like @ # $ % & ! ;

I finally figured out 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. here is the code I'm using to save data. [Code] Since I have them all saving to the "body", whatever the last box is in the code is what shows for all three once I click save. Does any of that make sense? How can i get all 12 of my text boxes to save to the form so that when I click save and then re-open it, they're all populated? Should I use the .Tag property (don't know how) or assign the data to an array somehow?
