Hides All Boxes And Labels And Displays A Datagridview?
Sep 1, 2011
i have a form when it appears it has 5 textboxes and 5 labels and a button. the user enters the information in all 5 textboxes and the button dims each as a string eg dim netno as string netno = textbox1.text
it then hides all boxes and labels and displays a datagridview.when the user presses the add record i want it to place the data in the netno in the column0 field for the new record and then focus on the next column automatically,

I have some combo boxes which displays one column of one database, and I want to trigger a query to it every time the CBox is changed, but as soon as the dialog with the cboxes opens, triggers itself..
Private Sub cbProd2_SelectedIndexChanged(sender As System.Object, e As System.EventArgs) Handles cbProd2.SelectedIndexChanged
'MsgBox("Changed")
txtQtd1.Text = "2"
End Sub
[Code]...
To test it I used the MsgBox and everytime the form opens it triggers the Msgbox 3 times each combobox.
I tried with SelectecIndexChanged and SelectedValueChanged but none of them worked good (I tried both isolated, one at time)

I'm trying to make a calculator that adds from two text boxes and displays the answer in another box, but It gives an error when someone enters a character. What can I do to display a string error message in the third box if a letter is entered in one of the first two boxes instead of a number?

I'm currently trying to make a beat generator, which allows you to add several labels (boxes) onto a panel, and then sound will be played when the "play slider" reaches the same x-value. However, i can't make the slider find the boxes. OK, so this is what I've got so far! Clicking my button, a label named sound0, sound1, sound2 is added to my panel_back (which is the background of the player) Private Sub btn_addkick_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btn_addkick.Click

I'm currently working on a program where I'm trying to dynamically create a picture box, a button, and a label for each item in a text file. Any ideas on how to do this? What I have: a plain text file with a list of numbers. Each number corresponds to a location. When that file is read, I want to create a picture box, a button, and a label related to each number. If I want to add something to the screen, all I Have to do is add a number to the file. So, lets say the file has. 1, 2
When the file loads, it will create a unique item on the display for each location. say pic1, button1, and label1 and pic2, button2, and label2. Right now, if I add something to the file, I have to go back into the editor and manually add everything. Which is a pain.

I need to create a form with radio buttons, text boxes, labels, etc.. This information needs to be pulled from a database. For instance, I have a form that displays information that needs to be inputed to a database, based on what test is being done for a specific product. Each product requires different tests. So each product may or may not have the same information that needs to be inputed..
What I have done is made a database and filled a table with each product and what tests apply. I then call that database after the product has been selected for the tests. It will then fill an array for that products information for what texts boxes and labels need to be shown. I wanna take this further and have it create a form through code and align all the controls to specific spots so that it will look nice. For example I wouldn't wanna create a control and have it be cut out of the form, or have other controls overlapping others.

I am making a program, where the user enters 6 numbers in 6 different text boxes, and it displays the larger of those 6 numbers. But I also want to make it where if the user enters a string value (like S for instance) in the text boxes, it gives an message and says "please enter the numbers again" and the user gets to enter the 6 numbers again. But when I do try to do that, it gives an error message saying conversion from "w/e the user entered" to Double is not valid. If the user just enters the numbers, it works fine. However, I am trying to make it if the user does enter non numeric value, it gives a message window and the user can reenter the numbers again.
Here is my code Example
CODE:
This is where I am trying to use IsNumeric to show a message if a user does not enter a string so the user can renter the numbers again, but when the user does enter a string value (say in textbox 1) it gives me an error message saying conversion from "S" to 'double' is not valid.
CODE:
Then right here this is where I have my series of ifs statements, this part works fine, it displays the largest numbers of the 6 textboxes every time. Error free.
CODE:
And do this with variable number 2, 3, 4, 5.
I know there are easier ways to do these with arrays and stuff. But I am not there yet. I am still learning about ifs and stuff.

I have the following code, which reads data from xml file and displays it in the datagridview. It all works fine:
[Code]...
Instead of showing read data in datagridview, i'd want to read the data from xml file into one dimensional array: X(Impedances) Or is there a way to read value from this datatable into string variable without getting data from datagridview? The point is: i'd want to scan through all "Impedance" values (which are read from xml file) and compare with value y to catch the nearest value to y. How to do that?

how to permanently save to text files then re-open all of the information again using SFD and OFD. Now my teacher has come back at me and said that i need to be able to save the information from multiple text boxes and have the text in certain labels to also be saved into the one text file (the labels need to be done because it is a database and these labels are like the fields and the right text box needs to match the right label)

I am using VB2008 Express and a MSSQL Server 2005 db by the way! I have a comprehensive SQL statement, which should fill my Grid:
DECLARE @Sum NUMERIC(9,2)
SELECT @Sum = SUM(I_LS.lmenge)
FROM dbo.lfs AS I_L
[CODE]...
Now here is my problem! I want to have a form with a datagridview that displays all of the values I am querying. This shouldn't be a problem I guess. However, I have no idea how I can integrate two textboxes that can be used to enter the selection criteria (WHERE I_L.lfsnr LIKE '%1253') AND (l.sped_journal = '11-08')[/SIZE]. I have googled and read many threads so far but didn't stumble upon anything that would suit my needs and answer my question. Maybe it's just too elementary!? By the way, it is very important that the input of textbox1 ((WHERE I_L.lfsnr LIKE '%1253')) is linked to 3 positions in my SQL query to define the search criteria!
The worst thing is that I don't want to have a bindingnav displayed! I do not need any delete, update or add functions just the select option, however!

i am using a couple bound comboboxes in a bound datagridview. It seems though, when the combo's are changed, and the tableadapter is filled again, the changes are not being saved to the table. Is there a special trick to getting the data in the combo boxes to saved when the values are changed?

I am building a simple GUI to view data within a database. I am getting stuck when it comes to filtering data. I have followed Beth Massi's video entitled How Do I: Filter data on the client?
However my datagridview will not filter, it simply moves the highlighted cell down to the location of the item selected in the combo box. The items in the combo box are also repeated as opposed to grouped by what they they are called, for instance I have a column called region and every cell contains the text "West" and the combo box just shows a list of all the cells as opposed to just one.I followed the video several times and every time this happens. Even with a new project. Could it be because my data isnt a table but a query of several tables? I can filter on this data in excel and access easily.

I created a program that has serval labels on a form and a listview object. It has a button that when clicked reads a textfile and loads up values in the listview object. I then can click and drag text from the listview box to any label on the form and then the program removes the value from the listview box. Now, my question is how can I instruct VB to save these values in the text property of the labels so that the next time the program is loaded the labels will contain the values loaded during the last run time session?

I have a datagridview bound to a bindingsource. This datagridview contains one column which is a combo-box.
Upon a click on a button,I change the underlying datasource. The selected values of the combo-boxes change.
But the change doesn't appear on the screen ! To make the changes visible (refresh each combo-box), I have to hover on the datagridview with the mouse or use the scrollbar !
Question 1 : why do I see this ?
Question 2 : what should I do to make the changes immediately visible ?

I have created a database with a couple of records to get started, also I have attemted to implement the database in my forms. I want to add, delete, edit and save new records into the database so when I use it or re open the program the entered data will still be there. Also, after I have implemented these things, I would like to be able to import data from the database into textfields or comboboxes. I have a basic email client and I would like to import these contacts into the datafields. However, I will be trying to achieve that later.I am trying not to use the data connection wizards as I am learning the code as I go along. I have been reading up on databases for about 2 days not and i'm still struggling.This is to add contacts with the fields.I have 7 labels with text boxes, using the naming convention lblFName or txtFName etc;
-First Name,
-Last Name,
-Nickname,
-Email,
-Phone number,
-Address and
-DOB
I have 4 buttons;
-Add record
-Delete record
-Save record
-Next record
-Previous record
I don't know whether to use datagridview, listboxes or something else to display the records.This is to give you an idea of what I have done so far.However, I cannot find a way; despite my best efforts over the last 5 days to link the database that is located in the same folder as my program.If anyone could point me in the right direction on how to code this into my program, or post some links of which I can read, learn and understand the code.

Well im currently developing an application for public use, I have a login screen in which the user enter's their registered credential's and the progressbar loads by increments of 3, now i placed 6 labels ontop of eachother and where the progressbar coding is i put:
If Progressbar.Value >= 1 Then
Label3.Show()
If Progressbar.Value >= 20 Then
Label3.Hide()
Label4.show()
And so on up until Label8 Show at 100%,
Now the problem is... As i have placed the labels ontop of eachother i need them hidden until they are called to show, i have tried adding a background worker to do this but have had no luck, all i see is the labels overlapping eachother when i run my application when i want them hidden untill Label3.Show() is called, and then to display them as they are called and hide them when another one is called to show...

I want to display (DataGridView's) selected row contents (each cell value on appropriate text box) on text boxes on the form. This should be fairly simple task for experienced i am sure.So far i haven't been able to find a single working solution to accomplish that as most of the articles are written for VB / VB 2005/ VB 2008 and not VB 2010.
Here is what i have already tried. (I tried putting an image but i can't due to my privileges over flow) TextBox1.Text =DoctorsDataGridView.CurrentRow.Cells(0).Value.ToString It strangely works for first 4 selected rows and populate text boxes but fails for the rest of the DataGridView.

With VB, but I've got the few basics down, file naming, adding objects, naming objetcs, etc. But the reason I'm on here is because I cannot complete even the first step. Our form is 640 X 480, and we need to have two labels, both have vertical scrolls. I know how to add and resize the labels to meet my needs, but I do not know how to create scrolling labels. Or are they text boxes? On our bubble chart (Do you know what that means?) it says lblInformation. We are going to have clickable radio buttons which will update the lblInformation with info about each of the radio buttons.

I'm trying to make a program that allows the user to click on labels which have a number in it and then that value has to be stored into a different label.
For example the user click on label1 and the values goes into label12, then it click on label3 and the values goes to label13 and so on.
At the moment I can only code on the respective label underneath (1->12,2->13...) but it has to be in any order (5->12,7->13...)
Here a picture and below my code:

I want to be able to have a dozen or so text boxes be emptied into separate columns in a row of a datagridview. This way the text boxes can be cleared and have new values entered then save the new values as a second row in the datagridview. This is so my VB gui which which runs everything through an old cmd line program, can do batches instead of one run at a time.
The problem is I have absolutely no idea how datagridview works. I've tried searching google and only found some vague things and stuff about databases. I also tried the MSDN library and that was of no help either, couldn't find anything on simply adding stuff and if I had it'd probably be to complicated to be of use to me.
