View 4 RepliesI have a VBA form in Microstation I am using to try and help automate a task. The only problem I am having is I am reading a textbox (Filebox.Text) and setting it as the variable (FN). It works, because I used Msg.Box (FN) to test it. However, in two of the lines of code, I am trying to use (FN) to pass the typed in filename to the command to run in Microstation. Unfortunently, it gets passed on as (FN).dgn instead of the actual filenale typed into the textbox. Is there a way I can make the variable actually seen as a variable? Code on Pastebin: url....Also, not sure if this is the right section, 100% new to VBA, coming from a world Bashed together.

When I declare a variable as public, shouldn't it be available in another form? I am trying to write a windows mobile prg with 12 static mileage points, form1 has the 12 buttons for start point, but when I call form2 with the destination points, my start variable value is not carried over. I intend to then assign a mileage based on the two points and write to file on mobile device. We support 12 schools, and I want my employees to track mileage easily.
Public Class main
Public start As String = "start"
Public dest As String = "dest"
Public miles As Decimal = 0

View 1 RepliesI have one form, which the user enters upto 5 websites then clicks go - I have on the second form, the one with the webbrowser. A timer which checks if the web browser is busy then either a green light or black image will be shown along side the assocaited input box on the first form.I am finding it impossible to feed variables into the clock through ByVal, like I would a subroutine or function.
Private Sub ActiveMe_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ActiveMe.Tick
If ((WebBrowser1.IsBusy)) Then
Hey.BackColor = Color.Black[code]....
'Error message says Hey is not declared, as i can't pass it through to timer
The variable Hey is determined by the first form - Which picturebox.I have an if statement which simply says if inputbox one has url enter then Hey = Picturebox1, If input box2 has url entered then Hey= Picturebox2 etc.What I want is the timer to check the page has completed loading or is still loading or refresing and the appropriate green or black to be shown aside url input box on first form.I considered using a sub or procedure to act as a clock (a large for loop with another for loop within it, acting as a delay). But found this slowed down theapp to the point of crashing it.
I have the following form: Imports System.Data.SqlClient Public Class Form1 Dim ReturnValue As Object = Nothing

I have a label in my Form which on loading, displays the contents of a text file. The contents of the text file may change and if so, the number of lines also will. I would like the Form to automatically resize itself based on the number of lines in the file. If there are more lines that the size of the label can take, I would like it to either resize or show scroll bars.
View 2 RepliesMy app has a group of forms that do a specific work in different ways. I want to create a new variable of a form when I want with its name. So, I want a Function in this form :
Public Function GetNew (byref f as form ) as form
That give a form name and return a variable of that type. In other words, it must work as "dim f1 as new formx".
I want to pass variables from one form to an other. The variables i I need in the second form( called" Hulsview") are :" hulsbreedte" and" hulslengte". To check if the varibles are passed I added a textbox in the second form,called" hulsview" to check the variable" hulsbreedte". The value selected in the combobox on on form1" hulsbreedte = HulsBreedte1.SelectedValue" returns always 0 in the textbox on de second form.
Here is the code form1:
Imports System.Drawing.Drawing2D
Public Class Form1
Inherits System.Windows.Forms.Form
Public hlb As Point 'not used

Well, my problems is follow. I use a textbox where the user can enter a text but which I would like to prefill out with a variable (later , with more experience, want to ask the AD for the username and put it in the box).
That means, when the user runs the app, automatically is the username written in the textbox without pushing a button but the user has the opportunity to change it (For example doesnt want the second surname).
I want al(InitialStrength.Text) to be set as the variable iST so I'm typing this at the top of the page before all my subs:
Public Class CharacterSheet
Public iST As Integer = Val(InitialStrength.Text)

but every time I do that and try to compile without even using the variabe, I get this error: "An error occurred creating the form. See Exception.InnerException for details. The error is: Object reference not set to an instance of an object."
I have an application consisting of 2 forms (Form1 and Form2).There is a text box on each form and they are both named Text1.From a sub routine in a module, I want to alter a text box on one of the forms. The sub determines which form to write to and attempts to refer to the form using a variable.But in the example below, gForm never gets declared when it's nested within the If statement.[code]The actual application is not so simple and I need to use this or a similar approach throughout the application in order to reduce code redundancy.To recap, I want to alter a control on a form by replacing the form name with a variable name.

View 4 RepliesI am trying to up a private sub routing based on the Text Changed Event for a listbox, inside of the event, I want to set a boolean variable to true. I have it set up, but for some reason it is not getting called.
Basically what I am doing is the user is being prompted to enter data in an input box. I am taking the data that is entered on the input box and populating it in a list box. I want to know if the text in the listbox has been changed, hence changing the blnIsChanged = True
Can I use text changed with a listbox???
Basically, I have a large number of text boxes. Within these text boxes, I'll be doing calculations based on user input and other things. These boxes will be grouped by numbers, eg Cost1, Profit1, Stock1... Cost26, Profit26, Stock26. Without too much explanation, I went to write a FOR loop to perform a repetitive calculation across multiple groups, and the following line came up.
FOR num = 1 TO 26
Cost(num).text = ItemCost
What I've tried to do is use a variable to decide which 'Cost' textbox, from the available 26, to use in the calculation. For whatever reason, it won't work. I would like to be able to use a variable to specify exactly which textboxes I want used, so that on the 3rd pass of the loop, the 3rd box is used, and on the 19th pass, the 19th box is used. Otherwise, I'd just have to do each calculation separately, and write the same thing 26 times, with slightly different numbers.

How do I make Variable eccessable to other forms in my app?
View 3 RepliesI'm trying to pass value from form1 to form2, while both form is open.
Using New (Dim frm as new form2) only works when the form2 is not loaded yet. what if both forms already open?
PS: I don't want to use module since there will be a lot variable to pass and i don't want to maintain such large collection of variable in module.
I have several instances of one form loaded. They all have an instantiated variable "Name." How do I select one of these forms based on the name variable?
Code:
Public Sub MakeForms()
Dim x as New frmBlack(me)
x.show
End Sub
My application sends information from Form1 to Form2 by means of a global variable on Form1 whose value is read by Form2.
This variable is basically used to tell Form2 what it has to do because it's value will change depending on different conditions.
All form2 is meant to do is load data from a database into DataSets which will "ported" to Form1 (the main form) for consumption. I use a Form for this rather than a class because there's a lot of data that will be loaded each time it's visible and I wanted[code]...
where I should declare my variable when using forms and the scope in my test code.
In my code below I have declared variable x in my form1 which can be printed in form2.
But when I create a structure in form1, initialize an array of the type protorec and try to assign values to cards(1).firstname etc... I get a "declartion expected" error.
Why does it work for x but not for cards(x) my array of records?
