I have an equation on Form1.vb that calculates a number. I need that number to be used in another separate formula that's on Form2.vb. How do I do this? I thought using a Module would work but I can't get the function on the Module to "see" the formula and/or variables that I need on Form1.vb. I am using VB 2005.
View 8 RepliesI recently bought a barcode scanner for God knows what reason, just to play around and now it seems that its easy to sort out everything at house with it (e.g. Disc Collection). So I decided that I need a special program for it to get sorted with the collection. I am new to Visual Basic, but used to do programs with Java 6 years ago, but it doesn't seem to be any similar to each other. Basically I have a Microsoft Visual Basic 2008 and here is what I want to do:I have Form1 which contains of a textbox and a button (which will be Enter further), a textbox for total amount spent (which has to be calculated from Form2 and a nice background. I also have a Form2 in the same project, which contains 3 textboxes (Title, Price and the barcode numbers)So my problems are: As I said there are just 3 textboxes in Form2. Is it possible to copy Form2 three times on Form1 with different variables in text boxes? For example Form2 1st copy will have one Title in textbox, Form2 2nd copy will have another Title in textbox and etc. The Titles are in excel (.xls) file.That is a problem further, but my problem for now is how to make barcode scanner working. The barcode scanner basically reads barcode and inputs numbers in a textfield and automatically presses enter.As I am new, I do not know how to make this work. When I launch the program the textbox has to be selected rightaway, so that I do not have to use mouse. As it is selected I read the barcode and the numbers are in the textbox right away and Enter key is pressed (but I did not assign OK button with a Enter key and I cannot output anything now). So how do I assign the button with Enter key and the textbox? Now as the button is pressed (OR ENTER KEY is pressed) The text in the textbox has to be selected again (so that I can input a new barcode) and Form2 has to be called on a certain place of the screen (e.g. 200x100px is the starting location).
Now when the Form2 was called it read the data from Excel spreadsheet and now the textfield in Form1 is ready to input new barcode. As new barcode was read the same situation is happening, but now the Form2 is copied into a new place with new parameters (e.g. 300x100px is the starting point).Same for the third time, but on 400x100px.For the fourth time the Form2 is not copied again. However the parameters of the third copy are getting the new data. Parameters of the third one are going to the second copy, second copy to the first one and the first one is stored in a text file or somewhere else to use further. (I wanted to use up and down buttons to search for what I have scanned)
Last one day I could not manage to pass data from one form2 other form.
When I am opening Form2 from Form1, I can pass data from Form1 to Form2.
When I am closing Form2, I want to pass data from Form2 to Form1 which is still open when I close form2.
I try to use shared textbox, but I understand that this is nt supported.

I know that
Public Incognito As Boolean
is a variable called "Incognito" that is class-wide that is a boolean.My question is that is there a form-wide variable form that can like communicate with different forms. So if a variable in form1 is "True" than, how can you make a variable in form2 turns to "True" too?
if in vb.net, I can call like this form2.show (), but how in wpf vb.net?

View 1 RepliesI have been converting my VB6 programmes to VB 2008, and I am beginning to regret it.According to the books that I am reading on the subject, I can call a second form from the first one. That is, when the first form code has completed, and the final line reads:
frmForm2.Show()
the second form should open and wait for input.This does not happen, the form flashes and then disappears without allowing any input, or button click.I must admit that I preferred being able to start from a module, with a Main() sub, which then read the forms, a la VB6. everything seemed to work fine then.
I made 2 form.
In form1 I have this:
form2.show()
form2 ends up behind form1, how can I make form2 appear in front of form1?
Form2.showdialog() will make form1 disappear until form2 is closed, that is not what I want.

I have a panel to form2 on my form1 which displays a picture box fine. I got a peice of code that stores 5 images in an image list and works off a keypress.
When I press the Comma key the image changes to the next one. This works fine on its own but when I put it in form2 and try to put the keypress code on form1 for it to change image in the panel it doesn't work.
I would like to do 2 things (or one of the two)
first, I have in form1 a textbox1 and i would like to bring the info of it to a textbox (or label) in form2
second, If it's possible i would like to set a picture from form1 to form2 (if that's possible)

I have Form1 that has a textbox and a button. When user clicks the button in Form1, Form2 opens up with a label control that carries the value of textbox in Form1.
What i did is set the textbox modifier of Form1 to Public, but when i call the textbox name of Form1 in Form2, i get an error that says "The name "txtbx1" doesn't exist in the current context". I wonder why since i already set the modifier of txtbx1 to Public.
Quick Note: i tried to instantiate Form1 in Form2 as:
Form1 f1 = new Form1();
and then call
f1.txtbx1.text
The odd thing is Form1 could not be instantiated (not highlighting occurs). On the other hand if i do Form2 f2 = new Form2(); Form2 gets highlighted!
This is how i show Form2 from Form1:
SetSalary salForm = new SetSalary();
salForm.ShowDialog();
Note that SetSalary represents Form2.

Using VS2008 I created a dataset in the designer and created a table with one column in the dataset. I pulled this table to create a DGV on Form1 and my column appeared (DS & BS were created on the form as well). It is on Form1 that I would like to initially populate the DT. (The DS is internal and does not have a connection string) On Form2 I would like to create a DGV and use the BS on Form1 as the data source. This is not visible, however, from Form2. I can set the data source programatically but then the column is not visible on Form2 until run time and I would like to make my formatting changes on Form2 using the designer. I tried making the DS and BS on Form1 both public but they still are not visible as a data source on the Form2 DGV.Is there a way to make a data source on a form visible to other forms in the project using the designer?

View 7 RepliesI have a simple problem and I believe that the solution is with module using but I could not resolve it yet. Here is the scene:In Form1 I have a variant that gets its value from the selections of a listbox. The code is:OPtext) in Form2 because this selection from Listbox (in Form 1) should also trigger some events in Form 2. I tried to use a module and declare the variant using Public. I did this and I now can use the variant in Form 2. But the value selected in Form1 does not come to Form 2.
