I want to use a form in vb.net 2010, so when I click on a button ,it must show me the info of a specific row in Exel and display info of that row in a text box.
eg.
Name Surname phone
Koos Leeds 08212122392
How do I start with this, any samples.
I am trying to do is fill out a form with certain info, put the info into an array, and write it to a listbox using loops, arrays, and maybe a function if I need one. This is for VB2010 and here is what I have so far... I think there are ways to make it shorter but I cannot figure it out.... maybe just brain dead from all the coffee I have been drinking!

I'm trying to make a simple game, but i have a question.i have a minimum damage and maximum damage lbl boxes on 1 form and i have a button if clicked it opens a 2nd form with buttons that deal "damage" when clicked
1. Attack (a regular attack that would deal the damage from form 1)
2. another attack ( this deals damage from form1 + 8)
3. another attack ( deals 30% damage for 4 attacks [so 4 attacks that deals 30% damage each])
4. another attack ( this one is great. it deals damage of 2 times of minimum damage to maximum damage and a third label box lblAP (attack power) which each 2 points of attack power you have it adds 1 more damage.)
i can do that math i just have no clue how to bring the info from form 1 to form 2.
I'm new in .Net and I have an application with windows form "LOGIN" When users enter the user and password and click "ok", then if user passes validation then I have the code Show(MDIMainMenu) (I'm trying to open an mdi form), but I receive the following error: "Form that is already visible cannot be displayed as a modal dialog box. Set the form's visible property to false before calling Show. Error Number 5"

How do I transfer info from one form in Access to another form in Access of similar fields, ie last name, first name, address, etc. without making the second form a subform? I have a command button on the initial form to send me to the second form, I just need to copy the info into that second form. This is what I have so for in the event procedure:
Private Sub Follow_up_Form_Click()
On Error GoTo Err_Follow_up_Form_Click
Dim stDocName As String

I have a program that uses two forms. The program opens to the Main form, and the user can navigate to the other form from the Main form through use of a button. Here's the way I've currently written it: When the Main form loads, it declares and instantiates the other form during the load procedure. When the user presses a button, the second form is displayed by means of the ShowDialog method. On the second form, there is a Return to Main Screen button which closes the second form, bringing the user back to the Main form.
So, here's the structure of the code:
Code:
Public Class frmMainForm
Dim frmSecondForm As New SecondForm
Private Sub btnSecondForm_Click(blah, blah, blah) Handles blah, blah, blah
[CODE]...
Here's my reasoning: Originally, I wrote the code so that a new instance of the second form was created every time the button was pressed. The problem was that whatever data was displayed on the second form, previously, was lost when the user returned to it a second time. Since the user would be switching back and forth between these forms, frequently, I needed that data to persist.
What is the best practice for accomplishing this:
1) Declare and instantiate the second form on program start, as I have done, and use the button simply to show the form?
2) Declare and instantiate the second form each time the button is pressed but maintain the variables on the Main form and pass them ByRef to a custom constructor for the second form? Is this even possible?
3) Something else?
Im trying to create a stopwatch in one form and another form show my progress bar using a combo box for mins and seconds to show the progress bar on form1 1
[Code]...
I am trying to use a progressbar to show on main form and then finish when next form is loaded, I have got this code.
1. When I click on button, it must open next form, but the next form must only open when the data in my list box has been loaded from Access Databse. When I run my program, it only shows the progressbar and don't open the next form.
Main form code:
Public Class Main
Dim PB As ProgressBar
Private Sub main_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
End Sub

Using the code below:
Private Sub ShowDropDown()
Using f As New DropDownForm
f.Visible = True
Do While f.Visible

This was a guess, after looking at the Form.ShowDialog method in reflector.My question is, is there a managed call I can make to acheive the same result, and what does a button click do that other clicks don't?
ETA: The problem does not occur if I open the form using a key.
This is a database app where I am trying to check for possible duplicates and give the user the option to keep the new record or assign to an existing record.In form1 the user will enter data into a textbox. I use this information to build a bindingsource.filter. Then I call another form (form2.show()) to display results to user and get user response. This part all works correctly.
The problem is that as soon as form2.show() executes, I loose the contents of the textbox - and it appears that I am no longer in the bindingsource.addnew() method.

It closes the whole app.
How would I change it so that it only closes the current form while opening a new one? EDIT: I put [Not Resolved] Because I accidently pressed the resolved thing
i used to write the code to show another form and unload the current form it always told error on UNLOAD form2.show unload me Do i have to use the code :
.Dispose()
or is there another suggestions
I have two forms , and I want write a code like ( form2.show=true & form1.show.false)
View 2 RepliesI have a series of methods being called for my networking code. An event gets fired from the networking thread. Inside this event, which I've hooked into from a singleton class, I route messages to form level methods which they register on form load to handle certain messages they care about. Inside of these form message hooks I need to close the current form (which I was able to do) but also show a different one (which is giving me the trouble).

why I need to instantiate a form instead of form.show?

I have a dual monitor setup on my computer. My program has multiple forms. I've designed the program to check which monitor the main form is currently on and to open the secondary forms on the current monitor. When the main form is on the primary monitor the secondary forms open as FormWindowState.Normal which is the design-time setting for the secondary forms. If the main form is on the secondary monitor and I click to open a secondary form then the secondary form is to be displayed as FormWindowState.Maximised.
[Code]...
So I moved the Form.Show line to after the Form.WindowState line. This works fine when the Form.Show process is very quick. The problem is that one of the secondary forms downloads some information from the internet so it takes about a second to finish the Form_Load process. When I had Form.Show first the form would not appear on screen until the Form_Load process is complete, so the delay was in the form appearing at all which is how I prefer it. With Form.Show last the form appears on screen immediately but appears mostly blank and unresponsive until the Form_Load process completes.
I would prefer that the form not appear at all until the Form_Load process is complete but I would like it to appear in an already Maximised state. Is this achieveable? It doesn't seem that complicated but I just can't figure it out.
how do you show information from a datagrid cell to show up in a text box in another form, this is for a college project.
View 1 RepliesI've come across a situation where I try to run a simple line of code in a method Dim res As DialogResult = frmOptions.ShowDialog()but nothing happens. The dialog box will not appear. If I run this method from another location in the code it executes fine (i.e. displays the form in dialog mode and code executes fine thereafter). Hence, it may be the way in which I arrive at this code that is causing my problem, but I cannot see to find what is wrong.
When I pause the debugger the line of code is highlighted in green but I can't see to step over it or into it what may cause this to happen, or what I should be looking for that might be causing the problem??

View 11 RepliesI have a database, and I am creating many forms that pull info from the db and write info to the db. I have a form that asks for a set of information. One of the box is a combobox that has a list of values. I have a button at the bottom
of the form that will allow the user to enter a new value to the values that populate the combobox if the user does not see the value they need. This will obviously populate a new form to create the new value.
I want the information on the first form to not be lost when the user hits the button to enter a new value for the combobox, yet I also want the combobox to display the new value.
Is there a way to save the information from the form and repopulate the form with the info the user entered? If I reload the form undoubtedly the form will repopulate the combobox and my new value will be there, since I have it reading and pulling info from the db on loading the form.
I am working on multiple forms that once the pricing is added to a list box and everything is totaled in label's will allow the user to submit the form and it will take them to a "receipt page" I have tried multiple times to get it to display and it won't. This is what I have.
Function CalcSalesTax() As Decimal
'Calculate the sales tax
Return decSubtotal * decTax_Rate
