I have written general module to transfer the grid values into respective textbox. For that I pass Listview control of form & parent control ( e. g. groupbox ) of textbox.
The module loop trrough each column of grid & store the value in respected textbox ( the textbox names are identical as that of grid column) It works fine, but when I pass tabcontrol it does not work
Its my first time here. And I'm a new to programming and to VB.NET too so please don't mind if I say or ask stupid things :POkay here's my question. Let's say I have a table which contains student details. (Student Code, Name, DOB, Sex, Address, Contact No) and I have a grid which shows ONLY the student code and the name.
Now What I wanna do is when you double click on a cell, ALL the data related to that particular row should be loaded into a form with textboxes.
I have a grid loaded with data. What I wanna do is when you double click on the row header, the data in that row should load into a form with textboxes. I've chosen the RowHeaderMouseDoubleClick as the evnt for this but dunno how to start.

View 2 RepliesI've been trying to make a grid to test some AI stuff I'm working on. I managed to do it using rectangles and graphics.rectangle (pens.black, rect) by using a vid on youtube, but it made the application virtually useless because of all the memory it was using. I don't need it to be an actual grid, but I do need it to have values as if it was a grid, so that I can issue commands (x,y coords). (I have been searching the forums for over an hour, but all examples are either useless or cant be converted correctly).
View 6 RepliesI have an infratistics grid that when I click on a row, the activerow gets set, then I click a button that will open a terminal form and ssh to an IP address in one of the activerow cells. It's not a problem until I connect to another row afterwards and it resets the activerow causing both forms to refer back to the latest activerow which would only be correct for the latest form opened. The problem then is that the terminal form refers back to the activerow cells for various updates. From my main form where the grid is, I open a new frmWodTelnet form to connect to the IP like this: [Code]
I haven't actually tried this yet, can't until next week just trying to get a grasp on how best to proceed. Does this look like it might work out for what I need, to lock the form values back to the original row until the form is closed? Or is there a better option I should be looking at.

I have a question and I hope it is a simple one. I created a form that "on-load" pulls a value from a .mdb query and assigns the value to a variable. This value is used in generating a new primary key for an associated table. The form works perfect except that if I close the form, and then reopen it, it does not give me the updated value which is written to the database. I know in VB6, you could use the "unload" method to exit a form and when you "loaded" the form again it would start new with the updated value. How do I go about this in VS08? If you don't understand what I am saying, here's the example...

I am doing a small MS Access database based program, but I got one problem. Instead of loading the the rows like this (each nr is the count of the row):
"1,2,3,4,5,6,7,8,9,10", it loads it like this: 7,8,9,10,1,2,3,4,5,6
Here is my code for where it loads the data:

I have a few combo boxes that need to be loaded up once and displayed multiple times (whenever the main form is opened) The reason for this is because it's taking about 10 seconds for the form to load each time it's opened due to unnecessary re-querying. Here is an example of what I have as a combobox source and what I've done. I've put the query, connection, etc... in a module and call it on the login form - I don't get any errors but the data does not load into the combos.
'In Module
sql = "SELECT DIR_ID, DIR_NM FROM LTC_FBS_DIR ORDER BY DIR_NM ASC"
RConStr = String.Format(RConStrFormat, LoginForm.txtUser.Text, LoginForm.txtPass.Text)
'using instead of dim connemp

Im working with a DataGridView with an imported CSV file where the values are delimited with (,).. The grid works perfectly fine. My ultimate goal is to hide the grid out of view from the user and access the data in the grid based on the coordinates of the grid specified i.e (The cell in column 5, row 6 contains the value "Taco") and I want to save that value to a variable...Eventually I want to loop through all the values of a column and save them to individual variables to be later used. So far, this is what I have...
Dim sReader As New StreamReader("book1.csv")
Dim Record() As String
For x As Integer = 0 To 17[code]....
Presently, that will only display the data in column 0, row 0 in those labels...
Note: 17 in the for loop is the amount of columns in the data i provided.. that number will never change.
Currently I have a problem with updating my database with values in my Data Grid View.
On my form I have a "Populate" button and "Submit Details" button.
The "Populate" button fills my Data Grid with numerous lines of data.
On the click event for "Submit Details" I want this data to be inserted into a table in my DataBase by looping through each record.

The problem is this: I have two forms. One form and the other form do mathematical calculations. I want to save the values that the user inputs, so when the user quits the program and then starts it up again the values are still there. But when I open up the program, start typing in values, then calculate them, hit quit. Try to open up the program again, its giving me a message that the input file is invalid. When I click ok, the program doesn't crash, continues. But the values are not there at all. The other form I put exactly the same code, just changed the variables and it doesn't want to save the values at all! I wrote this code for saving and loading the values:

I am almost there but for some reason I don't find the answer to my issue. Here it goes. In my application I have a form which displays a data grid view with some info I get through XML from a web server. The data grid view have as first column a Check Box colum. The second column have the information I get into a variable (from cells), one by one, to pass it to the sub with the XML command.
What I want to do is to be able to select all the rows and send the cell info of the second row (only for the selected rows) to my sub which will execute once then send the second cell info and execute the sub and so on until all the loop is complete. Currently my code works only if I delete one row at a time (sending the XML code will delete the info in the web server and update the datagridview which in return will remove the item).

I'm using a pattern of buttons verticle, & horizonal, to produce a 2 dimensional matrix (6 deep, 25 wide .) The sequence is repeating, but offset from horizonal line to line. the values are 1 thru 12. there are corresponding files in the "My.resources." file carrying names related to the buttons. If the "my. Resources" filename is say.., "1,3,4,6,8,9,11,12 " & the buttons pushed have produduced the string "1","4","6" then the prestated file carries all these values, and therefore should be selected. All integers of the textbox list must be present in a "my.resources" file to show the file. There will be multiple files in the resource file that will fit. (My ultimate intention is to show all files that fit, somehow. I'll have to, eventually. I'm still writing this, and changing it constantly. )the question is, "How do I get the computer to link the textbox integers to the resources files? Textbox = "1", "4", "6" to My.Resources.1,3,4,6,8,9,11,12

I have a table in access with 3 columns 1st is called userid and is a primary key and auto number 2nd is first name 3rd is last name. I have a button on my form and when I click it I want it to load the last userid listed in the access table and put in a textbox, say txtuserid. So if the records in the table looked something like
0001 james cold
0002 nick case
0003 john doe
When I click the button I want the last user id in the records to come into the textbox, so in the example that would be 0003, my connection is already set up.

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.
