Using VB.Net (Windows Application)In the form (called as FirstForm), i am using textbox, add-form Button, search button.When i click the add-form button, it will give the new form (same as FirstForm)Code for adding new form
Private Sub btnadd_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnadd.Click
Dim SecondForm As New FirstForm
SecondForm.Show()
End Sub
Search Button Code
Private Sub Search_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Search.Click
If FirstForm.Focus = True Then
FirstForm.textbox1.Text = gridview1.Rows(crRow).Cells("code").Value.ToString().Trim()
[code]....
The above code is working, but If i am in second Form when i click the search button and selected the value, then the value is appearing in the FirstForm textbox, it is not appearing in the SecondForm textbox.If SecondForm is showing, the selected Value should appear in the SecondForm textbox not in the FirstForm Textbox.
I am working on Visual Studio 2005, VB.At the back end,there is a table called "Marks" which has a column called "Subject". This column contains duplicate values.when the form loads,I want to display all the distinct values from the "Subject" column in the listbox.
I need to populate values from a database(Access) in to vb.net form. after selecting a field from first form, the next form should display all the parameters used in the selected field from the data base. Also if do editing it should be updated in the database.
Private ReadOnly Property Values() As Decimal() Get Dim X As Integer = 1
[Code]....
{"An error occurred creating the form. See Exception.InnerException for details. The error is: At least one element in the source array could not be cast down to the destination array type."}
i am having an issue populating two combo boxes on form load. The program will connect to an access database and pull data as instructed. Then as it pulls each record it puts it into the combo box.
This was working.. atleast i think it was. i dont recall it ever not working, however i wasn't looking for it.
My problem is that if when i load the MDI parent form and have it skip the selection form and the login form and load the next form in the sequence, it loads everything perfectly. However if the select form is loaded first, then the login form and then the form i need loaded, it will not populate. The only difference between the two different loads is that the login form calls a function that loads the form as a new project.form
I did this so that I can have multiple forms open at a time. I am assuming my problem is that I need to get the child forms handle then populating controls using that handle? but i think if I had to do that then I would beable to populate the comboboxes on the first form load using the login method of opening the form.
Here's my code.
vb.net Private Sub frmLine1t5_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load Me.Text = "Line " & LineNumber & " Test Form"
What I want it to do, is when a id is selected to be modified, another form will pop up with the fields are filled in with the relative data. Every time I run this I keep getting the following error -- "Syntax error in string in query expression '(the wombat ID selected)'"when it gets to the following line of "fillformDataReader = fillformCommand.ExecuteReader()"What is going wrong and how do I go about fixing this error so the new form is populated with the correct data?
Dim fillformCommand As New OleDbCommand Dim nameView, idView, regionView, sexView, ageView, weightView, lengthView, sampleView, commieView, descriptionView As String
I am new to VB 2008 express (I am a 'C' coder but have played with VB6 before). I am writing a simple program that will use the serial port. What I would like to do is, upon some trigger event, open a form, and depending on the amount of serial ports available, populate this form with an array of checkboxes with each check box corresponding to an available serial port. The user could then choose a port which would then determine the PortName.
I dont know how to dynamically populate a dataset based off the tables in an existing database.Once I can get the dataset to populate, I can then move forward with the next step of the project.
i have imported names from database table into combobox..i want to add item"all" above all names..how can i just add one single item in combobox after populating it form database tabel.
I decided to make a module to store all my Sub's for populating a TreeView on my main form. My question is, how do I make the Module.vb where I'm storing these Subs recognize the TreeView on my main form? I'm going to create subs such as this:
Public Sub Populatetest() Dim _GeneralNode1 As TreeNode = TreeView1.Nodes.Add("Test") End Sub
I have a combo box which is linked to a query which is looking up a unique reference number from a table called Tbl_Submitted_Requests.
What I need the form to do is auto populate the other text boxes when the user selects the unique reference from the combo box. How can I get the text boxes to auto populate with the data that is associated with each unique reference?
I have a simple windows form that i would like to send the values of a few textboxes and comboboxes to an rdlc report after saving them (I have VS 2005 standard, so no crystal reports) - it's as follows:
the textboxes are labeled length, width, height the combobox is labled unit of measure and contains two options - inches or centimetres the label has text of "your total cubic inches/centimetres is:" - followed by the unit of measure selected.the buttons are labeled save, calculate, print, print preview, and exit.Having said all of the above, the save, calculate and exit button code is easy enough and is good to go - it's print and print preview i'm stuck on the solution i'm after is to take those values and send them to an rdlc report that immediately prints (calls up the default printer dialogue) without preview or anything when the print button is clicked and also have a print preview function as well for when of course the print preview button is clicked.The report has already been created with the titles mentioned above..
I am using VB2008 Express and a MSSQL Server 2005 db by the way! I have a comprehensive SQL statement, which should fill my Grid:
DECLARE @Sum NUMERIC(9,2) SELECT @Sum = SUM(I_LS.lmenge) FROM dbo.lfs AS I_L
[CODE]...
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!
Inside a form, I would like to display a pdf file which is already available in my resources (template file "untitled"). In this pdf file, I have some fields which get their values from some texboxes in another form. My aim is, when the user triggers the button to call this form, it should insert the values inside the pdf file and display the output pdf inside the form.I have written the code to an extend but could not finish it myself after my many trials... Now here are the two things I cannot manage:I can use a directory to read the template pdf "untitled1.pdf". But my aim is to use the file inside my resources. can save the output file in a directory but this is not I want to do. I want to display the output pdf.
I have a custom form that I use instead of msgbox for a number of reasons. The initial reason was to keep the message centered on it's parent rather than the screen. There are many articles about this but I still have not found an elegant way to get access to the Parent's properties from inside the Child without passing them in (by one way or another).
In the child form the me.parent, me.parentform are not instantiated and apparently can not be used.
The point is to have this form be totally encapsulated with the logic being self contained. This is not an MDI child, and I do not want it to be due to the limitations on MDI children.
My current workaround looks like this I use a ShowMsg Function in my MyMsgBox form which looks like this:
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 know this has been asked, but can someone look this over. I have been going over and over this for about 3 days now. In my main form(frmBuildings) I pass a value to frmCustomerInformation like this.[code]...
Im having a problem when transfering values from form to form.Firstly I have a main menu form,click on a button to go to the dell components form.I choose the components for the computer and when i hit calculate the total is displayed in a textbox for my subtotal. When i press send it will send the sub total from the dell components form to the grand total and display it in the dell sub total in the grand total form.This part works ok, however, i go to the main menu and click on a button to go to the packardbell components form. Do the same again but when i press send, it will send the value to the grand total form in the packardbell sub total textbox but the value in the dell sub total textbox has vanished.Here is the code in the dell components form
Code: Private Sub btnSend_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSend.Click Dim frm As frmGrandTotal = New frmGrandTotal(txtDellSubTotal.Text) Me.Hide()[code].....
Finally, the other problem im having is on the main menu form when I click on the view total button I get this error: Here is the code for this bit
Code: Private Sub btnViewTotal_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnViewTotal.Click 'frmGrandTotal.Show() Me.Hide() End Sub

The insertion part of the form works great. But my problem is in the form load part......If i leave a field blank(Null),then perform Save operation,close the form after successful insertion and then reopen the form,then it retains the previous values during the form load......This is only in case where i leave a field blank in the previous data entry in the database.......But if i enter values in all fields then form load is working great.
I've created a module for my website and when a button is clicked, it calls a VB sub on the server.
I need this sub to retrieve the values that were filled in on the form, but the things I need to retrieve values from are not asp controls, they are simple <input> and <select> tags.
How can I retrieve values from input on a .aspx page from VB code executed behind it?
I have a form with 2 dropdownlists and a submit button. I want to pass the values of the lists in a URL when the list is submitted but for some reason the initial value of the ddl is getting passed. Here's my code:

How do you bring values from one form to another? Ive a car price which i need to carry over to another form as i have check boxes which if selected will change the price. How do i solve this?
I have two forms -DoctorAppointment -DoctorSchedule
the DoctorAppointment form has all the details about the doctor and the patient and one Schedule button which will show the DoctorSchedule form When I click on any value in the DoctorSchedule form like Monday or any other day and click on save button it opens a new DoctorAppointment form and store the Day value in the text box of the form. The old DoctorAppointment form stays as it is but the new DoctorAppointment form that appears after DoctorSchedule Save click it removes all the earlier values (doctor and patient Details) that were present on the DoctorAppointment Form.
I want that after the Save click it should not call any new form instead the Day value should come on the old form including the Doctor and Patient Details.

However, the issue is that TOtalAMount is getting updated automatically but FinalPrice is not getting updated. Any reasons/mistakes I have done. I have tried it a lot in few ways but could not get that working. What i did not understand is that Total amount is getting updated but Final price isn't.
