So my final goal is to take some columns from one form's datagridview (in form3) and place them into a seperate form's datagridview (form4). I started off by just trying to put all of the rows in there one-by-one. Later I will be moe picky about which rows I want. Below is the code I am using. The problem is that I am ending up with an empty form, but no errors.[code]

I have a form being called form several forms using ShowDialog().
1. Is there a way for called form to know which form called it by receiving a code or key from the calling form?
2. The calling form has a gridview. How can the called form pick up a column's value from the currently highlighted row in gridview in the calling form?
I have a base form and I am trying to get the DataSource of the ActiveControl if the control is a datagridview.What I have so far is:

how to pass value from one form into another form...? for example if i have 1 mdiform and 2 form (form1, and form2) for load form1 i'm using system.reflection.assembly here is the code for load form1 :
Imports System.Reflection
Private Asm As Assembly
Private FrmNama As Form
Public Function GetForm(ByVal FormName As String) As Form
[code]....
after form1 load i call form2 from form1 and from form2 i want pass value, here is the code from form2 to pass value into form1 :
form1.textbox1.text = textform2.text
why value from form2 can't fill into textbox1 in form1?
I am trying to copy a treeview control from one form to another. To do this I wrote the following
Dim tempForm As frmDoc
Dim tempTreeview As TreeView
tempForm = frmMain.Activemdichild
tempTreeview = temForm.treeview1
Me.Controls.Add(tempTreeview)
However this code moves the treeview from one form to another, it does not copy (or clone) the control.
I have a form that I am creating to document information about computers that I build. I have created the basic layout, what I have is a group box that has many different controls in it (text boxes, combo boxes, additional group boxes etc) What I want to be able to do is have a button that will copy the group box (computer information) and all of its contents and then paste it below the first group box with all of the fields blank or in their default setting; and keep doing this for as many computers as I want to add. Each project I do has a different amount of computers on it so I want this form to be able to handle any amount of computers.
I can't seem to find much on what I want to do, any pointers, direction or idea's
I was able to do this with an excel spreadsheet but all I had to do was reference and select a cell range, scroll down and paste the new section in. This is my code from excell, just as an example of what I did then. But with VB I'm stumped on how to approach this.

[Code] I want like to check if a file exist on main form, if not: force open settings form. And then when the user is closing the form with exit button = check if the file exist again. If it doesn't exist, close application. It's a huge application and I need optimized on most parts. Also, the settings form is asking the closing question two times.

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 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?
How can I update and get values in a Windows Forms application while moving one form to other form (like cookies)?
I need to update the values to some variable and again I am going to refer stored values and need to do some calculations.
I have used cookies in ASP.NET but I am not able to find out the same concept in .NET Windows Forms (C#).
How can these issues be resolves?

I was using 2 forms, the first one has general data capture and the second one is a calendar form. On Form1 I have mulitple windows controls. A Textb ox and beside a Calendar button. When I click on a Calendar Command button, it should open calendar form and once the user selects the date, the date should be placed in the text box on the form1. Identical to this on Form1 I need multiple textboxes that needs date to be captured.I cannot use a global variable for this as I need to validate mulitple text boxes. To explain this, I have a Transaction Date and Date Received. I need to validate whether Transaction date is prior Date Received or not? I dont want to use several global variables b'coz I might need multiple validations as above. Please help me on this.
View 6 RepliesI have been creating a call management application and I am having a problem with something that I have spent weeks on trying to get working and nothing I try is working for me. My application is an MDI application written in VB.NET 2005 Professional, using .NET Framework 2.0. It uses a back end database using Microsoft SQL Server 2005.When the MDI application launches, a form is displayed to the end user asking for phone number (MaskedTextBox) and a partner name. The partner names are within a ComboBox.
When the end user types in the phone number and selects a value from within the ComboBox, s/he clicks on the start button. This then opens a second form. The phone number from the MaskedTextBox is to default in a second MaskedTextBox (this I am able to get working without issue.) The partner name selected from the ComboBox is to default on the second ComboBox. This is the part where I have been working on it for weeks and not able to get it to function.
The second form has many ComboBoxes, all of which pull down items from a particular table within the database. Some of them are editable and some are not. The ones that are editable are also auto complete Suggest/Append on the ListItems.I wrote a sub to handle the population of these ComboBoxes and also to handle if they are editable or not. All of this is working. However, my main issue is that I can't get the value on the second form to default to what ever was selected on the first form. I do not get any errors but regardless of what I do, the second form always stays as the first item in the list regardless.
The code I am using is as follows:
<CLSCompliant(True)> Public Sub PopulateDropDownListFromDB(ByVal cboName As Elegant.Ui.ComboBox, _
ByVal TableName As String, ByVal ColumnName As String, _
ByVal UseAutoComplete As Boolean, _
ByVal UseSQLDistinct As Boolean)

View 7 RepliesI created a VBA project in Excel.

View 6 RepliesI have to write an application that consists of mainly one main form, but several different things I wanna display. Pretty standard I guess. So there is a menu, some controls, and the main stuff below (ranging form graphs, tables, dropdown boxes, print preview, etc). I would like to use it like one would use frames in html, design an object that is limited to a box or panel that I define. The literature I have does not give me a clear idea of how to do this (yet). The most obvious seem to be the use of MDI, open a predefined form with no borders, maximize it before showing and remove all minimize/maximize options. But that does not work so well. The form inside the MDI parent does not fit the size that is given for it when it is loaded. e.g.
[CODE]:......................
So my main question is: Is MDI the way to go here at all or are there better/easyer ways to achieve this? If MDI is the way to go, how do I sucessfully restrict a child form inside another object, without giving the user any opportunity to resize (i noticed that I have minnimize/maximize/close buttons, even if I disable them on the child forms themselves)

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!
