DataGridView - Error1Value Of Type 'Double' Cannot Be Converted
Jan 2, 2012
The error I am getting is: Error1Value of type 'Double' cannot be converted to 'System.Windows.Forms.DataGridViewTextBoxColumn'.C:\Users\Finley & Angelique\Desktop\Visual studio 2008\Mortgage Calculator CR 17\Mortgage Calcultor CR17\Form1.vb8922Mortgage Calcultor CR17
Public Class MortgageCaluclator17
'Write the program in VB.Net (not Web based) and have it accept user input of the amount, term and interest rate.
'Display the mortgage payment amount. Then, list the loan balance and interest paid for each payment over the term
[CODE]...........
If I remove the datagridview code the 1st part of the program runs fine and works well, it is when I add in the datagridview that the error occers.
I think I am missing something really simple. I want the user to be able to select a particular interest rate and term from radio buttons (in separate groups), the values for the buttons are to be stored in an array. Then they click the calculate button and it does it's magic and pops the result in to another field. I think I have things set up roughly the way it needs to. What I'm running in to right now is the term variable in the calculation formula is coming up with a blue underline stating that "value of type -1 dimensional array of double cannot be converted to a double". So as a result nothing is working right. I don't know where exactly I've gone wrong. If I change the data types nothing seems to change.
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Dim loanAmount As Integer = AmountBorrowedBox1.Text
This works fine . However , if I change the code to use the Select case statement instead of the If statement :
I get an error upon initializing the form , which says : String "" cannot be converted to type Double . Why is this happening ? The only detail I can add is that this sub is called on the CheckedChanged event of a Check box and of a Combo box . Luckily for me I thought of using the 1st code from the beginning , but on situations like these , changing from the If statement to the Select case is something that most probably won't cross someone's mind .
How can i get the same output as the VB results. And i have tired it ! Type conversions, math functions, everything i can think of to get the same VB6 output !
I want to use explicit conversion (CType function in VB.NET) to convert the variable d from double type to integer type and store the result as 132.
Imports System.Console Module Module1
Sub Main()

This is my code. But Visual Basic tells me an error: Error1Type 'i' is not defined.C:\Users\mihaispr\Desktop\Conversie explicita\Conversie explicita\Module1.vb1922Conversie explicita
I am trying to make it so when I use Me.Controls("Timer1") for example I can access specific commands for a timer such as Stop() Start(), I tried CType() and typed in "Timer" as the type but it says the control type can't be converted to the "Timer" type.
I updated an MS Access file with data and it showed the data is there. When I tried to retrieve I get this message " Conversion from type DBNULL to type Double is not valid" Below is the code to retrieve.
I am trying to create a program with vb.net. I am getting the following error in the form1.designer.vb and so I am not able to run the program. Its urgent. Error1Value of type 'String' cannot be converted to 'System.Windows.Forms.TextBox'.C:\Documents and Settings\Srivathsan\Local Settings\Application Data\Temporary Projects\Cyber Cloud\Form1.Designer.vb49119Cyber Cloud And it says that the error is with this line?
I have a problem, I cannot converted the value of Integer type, which it cannot converted to 'System.Drawing.Point' and 'System.Windows.Forms.Control' .
I have declared dob as date and the following code is to to call SQL server stored procedure but i cannot compile code because of error message (Value of Type 'Date' cannot be converted to integer).[code]
I'm a novice VB programmer and I am getting the above error when I try to display the results of one of my Stored Procs in SQL Server which doesn't need any parameters.
My code excerpt: Dim SQLCmd as SQLCommand = new SQLCommand() SQLCmd.CommandText = "Exec AllTableCount" SQLCmd.CommandType = CommandType.StoredProcedure SQLCmd.Connection = GlobalFunctions.GlobalF.GetDevSQLServerStoredProcedure(SQLCmd.CommandType) SQLCmd.ExecuteNonQuery() [Code] .....
I can see this SP from VS 2008 in the Server Explorer. So the problem seems to be that I don't know how to connect a data adapter to an SP. Just a string query.
In the below code I am getting the following error on line If (Not hash.Add(Numbers(Num))) Then Value of Type 'Integer' cannot be converted to 'System.Array'.
Module Module1 Sub Main() Dim array() As Integer = {5, 10, 12, 8, 8, 14} ' Pass array as argument.
I need to take 6 user entered dates and compare them to a date pulled from a database & stored in a variable. If greater than 6 weeks, then some action needs to take place.When writing the code, I get the following message (before compilation). Value of type 'Date' cannot be converted to 'System.TimeSpan'. [code] Within my code the 'dt' in the line above is underlined with the error message appearing on mouseover. I have tried using CType, as in dt = CType(Session("dt_occurence"), DateTime) in the hopes that might work, but it doesn't do it.
I have a project that you enter someone's name, home town and initials saves it to an array which later is produce into a pie chart.
The question is: The class has one method called addCompetitor that takes String parameters to indicate a name, home town and initials, and an Integer to indicate the position in the tournament. The method creates a Competitor object and stores it in the corresponding element of the position array.
Public Class Cakes Dim position(7) As Integer Dim amountSold(7) As Double Dim noOfCompetitors As Integer
I have used the following code to read a memory address from a pointer and offset previously however, Now I've come to use it again and can't figure out how I got it working last time, I'm receiving the error "value of type '1-dimensional array of Byte' cannot be converted to integer" highlighting the BytesAtAddress variable in the ReadProcessMemory calls.
Public Shared Function ReadPointerFromMemory(ByVal BaseAddress As Integer, ByVal PointerOffset As Integer, ByVal BytesToRead As Integer, ByVal pHandle As IntPtr) As Integer Dim BytesAtAddress As Byte() = New Byte(BytesToRead - 1) {}
[Code] As you can see, the code in the client side calls a function in the Server that generates an array as output. And this output SHOULD be loaded into the new array that was created in the client side. The case is that it is not allowing me to do that. The blue underlined row gives me the following error: Value of type 'ClientTest.TestService.ArrayOfString' cannot be converted to '1-dimensional array of String'.
I cannot see what is wrong, the function generates the same output type as the new var that is expecting to load it. Why data cannot be 'converted'? And what would be the solution to turnaround this problem? PS: Actually my function is a bit more complex than that and evolves a DB query, etc, but I reduced its code to simplify as the problem is occurring just in the array transfer.
A week ago, I encounter an error while doing my project. I failed to open certain form in vb.net. While clicking a button to show the form this will came out. "[An error occurred creating the form. See Exception.InnerException for details. The error is: Argument 'Expression' cannot be converted to type 'TextBox']".
How can I write this in an other way?System.IO.File.Copy(My.Resources.xxx, TextBox1.Text + "" + "blabla")I need to write this in an other way because I get this error:Value of type '1-dimensional array of Byte' cannot be converted to 'String'.
At the top of the code that follows is the method in c# into which I'm attempting to pass an integer value. Is there anyway I can change the assignment statement to the byte() PDUToSend to take care of the error I currently receive; Value of type 'Integer' cannot be converted to '1-dimensional array of Byte'.
Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick Me.BackColor = RGB(Rnd() * 255, Rnd() * 255, Rnd() * 255) End Sub
then i see this error:Value of type 'Integer' cannot be converted to 'System.Drawing.Color'
