I use Vb 2003 and SQL server as the DB. The SQL server is on the server. I use a RS to populate the Data grid. But for some reason the it wont populate and I will have to get out of my program and then load it back on for the RS to populate the grid. I tried putting a message box just to give the RS to receive its data from the SERVER but still it wont work. It does not happen all the time. I don't think it is a problem with VB or SQL SERVER, I think the Server is not returning the request.
I have a data grid, and I am pulling data from a mysql table. How can I populate my grid with the data? I also want it so when someone double clicks the item it will perform an event. How can that be done as well?
I have DataGridView control which i populate with some rows from the database the database table which i work with changes a lot so every 30 seconds I re-query the database to check if there is new record or existing record changed or record deleted, I can't clear and re-populate the grid view because people might work with it and they're might doing some changes in some rows.
so if the row was changed i just want to update the changes in the existing row without recreating it, if some row deleted i want to remove it and if a row was added i want to add the new row.
Populate a data grid view?I sem to have no problem understanding gathering data from DB and populating text fields etc but data grid I do not understand yet. [code]...
I have a DataGridView control that is bound to a dataset that I set up in design mode. This grid will contain addresses for a client. The relationship is 1 client to many addresses. So, when the user selects a client, I wish for this grid to populate with only the address records for that client. How do I set up in code a way for the grid to recognize this?
i am having sum textboxes and combos which have been populated accordingly. as in the attchment i enter the data in the textboxes/select values 4m combo and when click on save button all the related text is added to the datagridview's respective col. as desired. the problem is now that if suppose a user enters a wrong data and wants to edit/update the record already added the he will select the desired record from datagrid, double click and all the related data appears again on the combos and textboxes. the user then edits and click on save so that the selected record gets updated
Visual Basic 2005 I have a DataGridView on a form. It's bound to a DataSet, and I'm working by way through the dataset doing various things to the records based on the "status". What I would like to do is scroll the grid, so that the row that the program is 'looking at' is in the middle of the grid.
How can I retrieve data from a gridview to text box in VB.NET? I want to select the first row of values (suppose that it contains:rollno and name) and to display it in textbox1 and textbox2. That is, I want to display the values of selected rows.
I have a datalogger with his own program on Windows via a RS232 port. This datalogger records data in two ways :
1- continuously (see picture 1) 2- when pressing 'Start recording' button.
The datalogger record a value each 1 sec. Between 2 values, I need to move a stepper motor. I want to synchronize the stepper motor with the datalogger. So, right after the data is recorded, I move the motor and I wait for the second data to be recorded, etc. The problem is the synchronisation. I have access to 2 triggering method when the data is recorded :
1-when a row is added in the grid (picture 1) 2-when the 'Recording' value change (from 5 to 6 by example)(picture 2)
The easiest option would be the second one because the 'Recording' value isn't a textbox, it's included in the general form. I cannot access to it directly. The class of the datagrid is Thundergrid and his name (Caption) is LIST. I want a VB program that will do the following..When I press a button in My Form :
-Get the handle of Thundergrid class, LIST named. -Wait until the datagrid row number is 10. -Then, a variable n will count +1 at each added row in the datagrid. -Each time the n value will change (datagrid add a row), the motor will move. -When the n value = 121, the cycle is done and I can collect the data.
For the interaction with the motor, it will be done by grounding a pin in the parallel port.I do not need help with the motor control, only the n value need to be synchronized with the datagrid.Please refer to the attached pics. I used Winspector to get the class of the datagrid. It is in the red box.

This works fine. But when the grid is dropped on a TabControl tabpage, the ctrl-tab looks very different to the sub above. e.keycode is seen as controlkey {17} I realize that by default cntrl-Tab moves between tabpages. I need to override this behavior. My thought is I probably need a subclass of the tabControl which will pass the keycombo through just as the form does but I confess to being clueless as to how to accomplish that. I tried to override the onkeydown of a tabcontrol subclass and just issuing a return and not and base call to onkeydown if the ctrl-tab combo was pressed but it seemed to see the e.keycode as controlkey as well.
I have a program that contains a 2d grid of panel objects and I just realized that the computer I need to run this program on does not use .Net4 and I cannot upgrade its framework either. Because of this, I have to rewrite the program in vb6, which was not so bad until I had to make the grid of panels...
Here is the code I am using in vb2010 to make the grid and I was wondering how to transcribe this into vb6.
Dim regionGrid(0 To 37, 0 To 37) As System.Windows.Forms.Panel (in nested loop)
regionGrid(i, j) = New System.Windows.Forms.Panel()

How do you read a CSV file and display the results in a grid in Visual Basic 2010? This sounds so simple but I still can't find the answer to it after googling for a while.

I am student of MCS and i am working on my final project i face some problems regarding to show cubes data in grid control in vb.net around with dimensions
We are creating a VB program for school to collect data on student attendance and populate it to a table. I have all of the 'GET' statements but am having trouble creating the 'Insert' procedure. This is what I have so far. The form being used to fill the table has 4 items being recorded. 'Present' radio button marked as present, tardy or absent; StudentId, PeriodId and date. Not sure if we are on the right track. The target table is tmAttendance. There are approximately 25 rows of data on the input form.
This is simple program, draws a rectangle, marks the x & y axis, & plots a dashed line grid. However, the grid sub has to be called twice - only then will the grid line be visible. Why does this happen?
