Reference The Values From Textboxes On Form Submit That Reside In Usercontrol?
Aug 18, 2011I have a large form that reuses several elements, so I decided to create a usercontrol with some common fields. The problem is when the form is filled out by a user and submitted, how do I reference those values so I can input them to my database???
Example:
Using Conn As New SqlConnection(connect)
Using Cmd As New SqlCommand(SQL, Conn)
Cmd.Parameters.AddWithValue("@Acct_Company", txtPartner.Text)
Cmd.Parameters.AddWithValue("@Acct_AccountNum", txtPartnerAccount.Text)
So, above two Cmd lines are for normally inserted textboxes in my form, but what would the line look like to reference any usercontrol form fields?
Namespace Does The Month() Function Reside In
Mar 26, 2010I'm not at all familiar with VB but do occasionally use C#. Really, i'm a BI guy who uses T-SQL on a daily basis in SSRS, which is why I have a question.I have a scenario where i've built a series of charts in SSRS 2008. Unfortunately, the functions available to me in SSRS are not enough for what I need my charts to do so I have decided to build my own function in embedded code. In SSRS, only VB.NET can be used when writing embedded functions.
I have opened Visual Studio 2008 Pro, created a solution and started building my function in Visual Basic 2008. So far, all is going well - i'm accepting a parameter which contains a string "date" of JAN-10, doing a substring operation on it to parse out the month and year, concatenating "20" to the two-digit year portion to get the full year. This part all works just fine.
For the three-letter month portion, i'm trying to use the MONTH() function to return it as an integer but unfortunatley it does not seem to be availble to me in Intellisense, which of course probably means i'm not accessing the class correctly. The odd thing is that the MonthName() function is available, but of course I can't use this with string values like "JAN" or "FEB" because it only accepts an integer. I'm familiar with the fact that in C# I can add a USING statement to the top of my class file to access a namespace, but i'm not sure how it works in Visual Basic 2008 because i'm honestly never used it before.
So my question - and this is probably a very basic question here - how do I access the Month() function? Which class or namespace (or both) do I have to reference in order to use it?Below is a screenshot of what I have so far, you can see from the Intellisense menu that the Month() function is not available:

Dec 23, 2010I have an app I created in Vb2010 (my 3rd VbApp) it is a file converter which works but all it does after convert is... I have a converted file but no file name plus it converts within its own directory as opposed to convert in dir where original file location.
So any clues as to how I always use file to converts name as defa and where the converted file will reside same dir as original file?

Calling Form-name By Variable?
Jun 25, 2010i am currently trying to re-write an old VB6 program into .net basically the program contains 100's of forms for different jobs each with a Public Sub runjob(). the form names are then stored on a database. the user then selects the job from the listbox and it calls the correct job.the code i use to use in vb6 was
sValue = database.rsselectjobrun.Fields("callname")
Set frmName = Forms.Add(sValue)
frmName.runjob
Set frmName = Nothing i have looked into it and found this code which calls the form in .net
Dim objForm As Form
Dim sValue As String
Dim FullTypeName As String
[code]....
but i cannot get this to run anything other then the formload code. i know i can put all of this into a select case module but id rather not with the amount of forms i would have.
Declaring A Variable For Form And Using It?
Feb 8, 2010I have declared this variable in a module : Public GenericForm As System.Windows.Forms.Form
and then through code I can asign to that variable a specific form .For example GenericForm = Form1. Then I can use that variable to handle that specific form , for example :
GenericForm.Show
My problem begins when I want to handle a control on that form , for example :
GenericForm.TextBox1.Text = "aaa"
This code creates an error reading :TextBox1 is not a member of System.Windows.Forms.Form.I have been using code like this in VB6 and was quite useful ,but now in VB .NET I cannot .You see I have many forms on which there are some text boxes with the same name,so I declare a generic variable as Form and accordingly insert the code the desired text box conform the form I wish each time . Can I do this in VB .NET too ?

View 9 RepliesReference A Form From A Variable?
Nov 24, 2009I am upgrading a very large project from VB6 to VS2008. I have several forms with dozens of combo boxes on each form. I use the same combo box names for each form and want to fill them from a module with different items depending upon the calling form. In VB6, I dimensioned a public variable - FormName as object and called Set FormName = frmMyForm1 on Form Load. In a module, I was able to write the following code:
With FormName
.combobox1.additem("item")
.combobox2.additem("item"
End With
I cannot make this work in VB.Net. When the form loads I call FormName = Me. If I dimension Friend FormName as Object, I get the error message that Public member combobox1 on type MyForm1 not found. If you are attempting to access members on a late-bound object make sure it is declared public". If I dimension Friend FormName as Form, I get an error that says "combobox1 is not a member of System.Windows.Forms.Form".
I have tried both CType and DirectCast to convert the form variable from Object to Form with no success. I also tried creating a public array and storing each form name in it.

VS 2005 - Variable From One Form To Another
Jan 3, 2011I have two forms and I need to take the values from the first form and add them to the second form. I have tried many things and nothing is being added or changed yet on the second form. The second form has a Panel as a background, then a GroupBox to group items together and then the relevant controls themselves. I have been working at this for the last few hours and not getting anywhere and needs a second pair of eyes.
I have tried DirectCast() and it doesnt work. Nothing happens. The data isnt added or the control selection isnt changed. No errors either. I have tried Me.ControlName.Property = FormName.ControlName.Property and it doesn't work. Nothing happens. The data isnt added or the control selection isnt changed. No errors either. [Code]

View 1 RepliesCopy A Form Object To A Variable?
Jan 8, 2009Is there any method or a way to copy a form object to a variable? Let me explain this - We have a method called "Copy" for the Dataset class & you all must be knowing that there is a difference between the below two lines of code: DsTemp = Ds DsTemp = Ds.Copy()
In the first line of code, any changes made to Ds will reflect in DsTemp. However, in the second line of code, any changes made to Ds will not reflect in DsTemp because we are only "copying" the contents & schema of Ds. Likewise is there a method or a work around to "copy" a Form object?

Declaring A Variable TableAdapter On A Form
Aug 15, 2011I am building a generic search form in my application. This will allow the user to search for various records throughout the application. The one thing I cannot seem to figure out is how to allow the declaration of the TableAdapter to change at run-time. Each part of the app will be passing a variable to the search form to specify which table should be loaded. In the form class I have the following:
FRIEND WITHEVENTS tbaSearchData AS database.databaseTableAdapters.TableOneTableAdapter This is great for TableOne. But, I have about a hundred tables that could be searched through. To load the data I'm using a DataGridView and populating it via a private method.
Forms :: Can't Pass Variable From One Form To Another?
Jun 8, 2011I 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.

Forms :: Reference Form Using Variable

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.
