I am at a stand still on this one. I know how to connect and add to the database, I just don't know how to retrieve the information so that a user can see it! If anyone could help me with code or another example.
View 4 RepliesI'm creating a project for my brother's thesis for his VB subject.Now, the thing is, I'm trying to display row data from database to the (already binded) textboxes in form1. As you may know, this procedure requires that the program:
1. Declares an sqldatareader, sqlcommand, and an sqlconnection.
2. open the sqlconnection.
3. ....and use the sqldatareader to fetch the data from the source file.
The database file is made using sql server compact 3.5 and is located on same pc as where I'm making the program.The problem is, I'm getting stumped in trying to connect to the sql server. I'm getting a 26 error "error locating server/instance specified". installing sql server 2008 management studio to allow remote connections (which was already allowed in the 1st place), enabling TCP/named pipes protocol in the config manager, and enabling sql server browser service. I dont have spi firewall on since my isp has its own firewall on and xp fwall is off too. What I'm not sure about is my connection string as it might have been impeding me to connnect to server. How do I form out the correct connect string?

View 2 RepliesI have a program in which I want to have the user enter two percentages and display the data matching the criteria on a new form. The query would be:
Select *

Where corrpct1 >= {column in database} OR
corrpct2 >= {column in database}
The way I currently have it written is to display only one row of data. I need to display any number of rows that meet this criteria. My current code is:

2. How can I display ALL of the data instead of just one line?

Is it possible to have a Textbox on a form that when the user inputs data, ( during Runtime )that data remains in the Textbox for good and the Textbox then becomes read only ? Is it also possible to make it so that the CD with the programme on, is in the PC when the programme is being used. Perhaps writing the Textbox data back onto the CD ?

Private Sub btnDelete_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnDelete.Click
Try
btnSearchEmpNo.Enabled = False[code].....
Now I wanna set when user click on this button to delete a employee (for example) then the datagrid that i have in my application will not show the data of the deleted employee but in the background, the employee haven't been deleted from database.The employee only will be deleted from database when the user click on SAVE button.I know this application have to use RowState but how?
I have a database I am creating with about 50 users over a network. There are about 6 groups of users and these users are spread across 10 branches. I want to block/allow users from particular forms and views. For example I want branch users forms to be filtered by their branch number but depending on the group they are in they can only see some forms. i.e. 50 users, 10 branches, each branch has about 5 ppl of where 1 is in group A and 4 are in group B. I want all users that belong to branch 1 to see the information they enter, but Group B enter data but cannot approved or delete, and group A can enter, approve and delete. So then. On my login form I have the user type his/her username but the i want LEAVE function to update 2 textbox where I have named GroupName and BranchNo. Basically to run a query and look for the username and return in one textbox that user's groupname and the other textbox the user's branch no. This information will be used to filter forms and block the user from certain controls. This is the code I have so far but still can't figure how to display the results.

View 1 RepliesI have developed a small application. It has a MDIParent form on which the other childforms are displayed. I have a Panel on the MDIParent on which there are buttons to call up the MDIChild forms. Now my issue is, when anyone of the buttons on the MDIParents form Panel are clicked, it should check if another Childform is display, if it is then it (the active childform is closed) and the new form will be displayed. This part is working fine from the code below. However, when there are no active MDIChild form on the MDIParent form and if the button is clicked, the 'Else' part of my code below is executed. This generates the error as 'Object reference not set to an instance of an object'. So what is wrong with my code below?

View 1 RepliesI am working on an aspx site that lets an admin-level user fill out a form with potential member data. Once the form is filled out, the user will click submit and the data will go off to different tables. One part of the form that is stumping me involves filling out three textboxes (txtFirstName, txtLastName, txtGrade). I have a button (btnAddStudent), that, when clicked, should add the information from the textboxes to a table-like display area. I am trying to use a gridview, but there is nothing to bind it to. There is no memberID number to load a blank record from the Student table (which is a many-to-one relation to Member table). The member record is what this form is creating, and the student data will be added to the Student table when the Submit button is clicked.
I am currently working with the code found in the reply here. But when I click the "Add Student" button, I get a new blank row, but my textbox values are not inputted in the gridview.
Can this work, or do I need to look at using a table and adding rows of textboxes dynamically?
Here is relevant source code:
