Passing An Amount Back To An Other Form?
May 25, 2009
I have a CheckingAccountForm and a CheckingAccount class. I have 2 variables AmountEntered and TotalAmount. The user enters an Amount and hits the calculate button. So now I send the AmountEntered to the CheckingAccount class where it is added to the TotalAmount and I have to send the TotalAmount back to the CheckingAccountForm so it can be displayed in a textbox. Can someone give me an example on how to do that? I get the AmountEntered to the CheckingAccount Class and managed to calculate, but not sure how to get the TotalAmount back so I can display it in the GUI's TextBox for the TotalAmount.

I need to pass an uint8 array from C++ DLL to VB6 application but I receive always following error: "subscript out of range" if I try to work with the array 'pabyData' in my VB6 procedure. The C procedure is: typedef void (__stdcall *FUNCPTR2SendData) (const uint8_t* pabyData, uint16_t wDataLength); void SendData(const uint8_t* pabyData, uint16_twDataLength) { FUNCPTR2SendData vbFunc; vbFunc = (FUNCPTR2SendData) ptCBFPointers->p2NewDirectDataSMSEvnt; // ptCBFPointers are call back pointers, where is saved the call back address of VB6 functions vbFunc(pabyData, wDataLength); } The VB6 procedure is: Public Sub SendData(ByRef pabyData() As Byte, ByVal wDataLength As Integer

I have created an application that I am using the VB webrowser control. The users needs to login to a site to display a particular webpage. The sites login is in a popup and what appears to be happening is the popup is launching outside my application (has IE in the title). If I enter uers/pass and try to login the information is not being passed back to my webrowser form.

I have a search page with a couple of pulldowns. Dependig on the values of them I show a grid matching the searched criteria, basically a table with links the user can navigate to. My problem comes when the user wants to navigate back. At the moment I have a "Back" button which simply redirects the user to the initial search page. I think it would be a good improvement to have the values of the pulldowns filled in with the values the user selected, this way when he presses the "Back" button he would not have to restart the whole search process again.

Can anyone give me the best method of passing back a value from a Thread?I have some procedures that I have set up as threads that I'm starting at the same time.My main function then waits until the threads are done and I'm needing to get back some values that the threads have created.Is there a better way to get these values back rather than just having them set a global variable with the returned value? Also, what is the proper way to wait for a thread to to be completed?I've just got a loop waiting for the Thread. Thread State property to not be in the Running state.So if there is a more proper way to wait for the thread to end I would be interested in knowing it.

I have a project now where I will have a large chunk of CSV text, like 60 lines or more, and need to pass that from the client to the server. I know it would be weird with GET, but how would I store the multiline text so that I could later split it up, etc at my application?

Here is my case:I have a richtextbox called Rtb1 I have the text property for this control set to "ThreadAmountEdit=[Thread Amount]" This was set through the RichTextBox Tasks function, by clicking the control and selecting the little arrow in the top right corner. In working on my form, I edit the text "[Thread Amount]" of the rich text box to "45". What I need is to be able to reset Rtb1 back to default ("ThreadAmountEdit=[Thread Amount]")on button click.
I've tried: Rtb1.Refresh() which doesn't appear to do anything I've also tried Rtb1.ResetText() which completely clears the textbox.

im trying to make a simple program that calculates the time it takes to cover x amount off nautical miles at x amount off knots, the code i have so far is this :
Code:Public Class Form1 Private Sub Label2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Label2.Click
End Sub
Private Sub TextBox1_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TextBox1.TextChanged

im trying to make a fast food program on which the user will input the amount that he has, then he will check on what he wants, by using check boxes. There are 7 different check boxes with 7 different amounts of money. I have the program somewhat finished (thanks for the people that helped me before) but theres still a couple of things that I still need to get finished but I dont know how to.I need to be able to get how much money the user has (this will be entered threw a text box, I think I accidentally messed this part up, because I cant get it to work right, (theres alreasy a permit amount of money in there and it needs to be what the user enters instead of the permit, 5.59, one) and this will be the maximum amount he can spend, then the user will check on the food he wants (and the program will add the sales tax also) then it will produce an answer saying if you have enough money or if you dont. But what im confused on is how do I get the users amount of money and make it the maximum mount he can spend and make sure it doesnt go over the amount that he has checked.[code]

I'm upgrading a project from VB6 to VB2008.I have a routine that clears a combo box, named 'cmbDataTable' which could be on any form. I pass the form and the combo box is cleared.
[code]...
I assumed it would be the same in VB2008 but I get the error.'cmbDataTable' is not a menber of 'System.Windows.Forms.Form'I am working my way through the project, first updating the global procedures - this is one - I haven't written the calls so cmbDataTable doesn't yet exist.

I am trying to pass information to parent form from modal form in vb.net winforms application.
1.) I created a copy of a form and displayed it using following code.
dim f=new frmParent()
f.show()
2.) Depending on conditions a button on frmParent opens a modal child form and asks for some informations. I used following code for that:
dim f = new ChildForm()
f.showDialog()
Both code works fine. When user press saves in child form i need to close childForm and use the user types values in parent form. I know how to close the childform but not sure how to pass info from childform to parent form.

I have 3 forms, the form one is an intro, form 2 loads a user and form 3 displays a user. i use the streamread / writer to load values on form 2, then when successful it loads form 3 and the vaules are transferred perfectly, now to save time i changed the start up form from form1 to form2 (saves having to skip every time). so after having all the code load and transfer i wanted to see it in action and then the issues started.

I have a 2nd form that is minimized to the taskbar, I can click on the tab and the form opens and shows all of the data fine, but
From the main form, I am maximizing the second form and trying to pass a value to a toolstrip textbox on the second form then press a button on the toolstrip from the second form, I can get this to work fine, but where I am having a problem is
The button searches through a treeview, when I step through my code, I can see the value that I am passing, my code does execute, but the treeview is showing no nodes(but they are really there). At the begining of the code, I put a message box to give me a count of the nodes in the treeview, it shows 0, but I can see all 10000+ nodes. What the textbox is on the toolstrip is a search box. When the form is maximized, I can enter whatever and it finds it with no problems, but if I pass a value it doesnt find anything because the treeview is saying there are no nodes when there is.
