I have a routine that exports data to HTML and works 99% of the time but now and again I get an error of Index (zero based) must be greater than or equal to zero and less than the size of the argument list on this specific line of the code
Now sRetMessage is declared and passed as a string and contains approx 5 lines of text with <br /> for each VBNewLine.
What I did notice is on one of the errors I have caught, the last 3 characters on every line are =20 sRetMessage is extracted from a text file and so the contents are out of my control.
why i'm getting this error? If it is the =20 within the string, why should this matter as it has been stored and passed as a string value
The reason this is being done is at this point we have no idea what the column contains.However, if the formatter is "{0:MM/dd/yyyy}" and the DataRow("ColumnINeed") is an integer containing 42, String.Format is returning: MM/dd/yyyy In this situation I need it to throw an exception instead of returning nonsense.Is there anyway to make String.Format throw an exception if the object does not match what the format string is expecting?
So I need a format string to pass to String.Format that would "move" the decimal point.I can't perform any math operations before doing the String.Format, so it has to work right off the bat.Basically I'm emulating a formatting string from a proprietary server. In it if I say:
"MR2"
for the value:
12345
The result is:
123.45
I'm close with this, but it's not spot on:
String.Format("{0:#0.##}", 12345)
an extra, but not necessary... there is also MR2Z, which moves the decimal 2 left, but if the value is 0 "" is returned.
I need to take a string formatted like '010711' (DDMMYY) and put it into format '01-Jul-11'. Ive thought about doing something like string.toArray and then having some conditionals that format from there but am looking for an easier way.
I am trying to get a textbox to have a time value of mm:ss. I am trying to make sure that what the user has entered is in the correct format. i.e. If a user enters in 0923 the exception would be thrown. But if 09:23 is entered it would pass through. Below is the code I currently have. I have tried 3 different things and none work. Any help would be appreciated.
Thanks
Try 'If txtRun.Text <> Format(txtRun.Text, "{0,mm:ss}") Then 'If txtRun.Text <> Format("{0:mm:ss}", txtRun.Text) Then If txtRun.Text <> Format(txtRun.Text, "{0:mm:ss}") Then Throw New BadTimeException("Please Enter a Correct Time") End If
Catch BadTimeExceptionParameter As BadTimeException MessageBox.Show(BadTimeExceptionParameter.Message, "Invalid Time", MessageBoxButtons.OK, MessageBoxIcon.Error) Exit Sub End Try
We have a winforms appliction that has to talk to an AS400. To do this we imported the IBM.Data.DB2.iSeries classes in the Winforms application and have IBM System I Access for Windows on our machines. It must have the System I Access or it will not talk to the AS/400. Everything works fine on my 64bit development machine. It also works fine on the client's 64bit machine. However when we attempt to install it on a 32bit machine we get a Bad Image format exception. We tried making just an x86 installer instead of any cpu but that did not work (same bad image exception).
My code is not working it highlights this intHoursWorked = Convert.ToInt32(strHoursWorked) when i run the program and says 'format exception was unhandled' ? Someone said to just initialize the value of lblleftoverminttl ,txtttlminworked, intHourlyPayRate but im not sure what that means?
Here is the rest of my code:
Public Class Form1 ' Weekly pay for an hourly employee
Private Sub btnWeeklyPay_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles

I had a working program a while ago, but now it is giving me an error when I try to insert some data to my Excel-file.I get this error: Old format or invalid type library. (Exception from HRESULT: 0x80028018 (TYPE_E_INVDATAREAD)) For example, one of my Excel referencing codes is:
Dim XL_App As New Excel.Application Dim XL_WB As Excel.Workbook = XL_App.Workbooks.Open("C:Program FilesIAAExcelitTuntilappu.xls", , True) Dim XL_WS1 As Excel.Worksheet = XL_WB.Worksheets(1)
The above code used to work, but now it gives me the error...I recently updated my Office from 2003 to 2010. How can I fix it?
I have a field that I display via: String.Format({0:c},amount) This produces the string "$28.28" However, when I try to convert back to a decimal amount, I get an incorrect format exception: amount = Decimal.Parse(amount.Text, NumberStyles.Currency) I also tried it with NumberStyles.AllowCurrencySymbol with the same results. I verified that the value in amount.Text is "$28.28". Am I missing something? Shouldn't these two operations use the same currency symbol and formats?
I'm trying to create a print function with a corresponding print preview. For some reason, any string I create with String.Format will NOT show up on the print preview! Use the code snippet below as an example:
Dim strTemp As String strTemp = String.Format("{0, 210} {1, 75} {2, 51} {3, 200} ", "NAME", "PRICE", "QUANTITY", "DESCRIPTION")
rs2.Fields("Field29").Value has values like "YYYYMMDD" in a string.how can i convert a "YYYYMMDD" string to a needed date format like 'dd mmm yy' (or any format)
I am trying to use string.format on a url to pass several values into the string. It's probably a simple error but I cannot get the following code to work. It doesn't even build the string.
Public Sub getStockData() Dim client As New WebClient() Dim url As String
It is possible to catch an exception and throw a new exception which wraps the first exception as an inner exception: [URL] Also, if I call a function and it throws a certain error, but I catch it, will the calling code's catch handler execute? If so, and it is of a higher exception type, is this not wrapping the exception? eg I can throw exception ex of type IndexOutOfRange, log it but rethrow, catch a higher up exception and do something, or I can throw a new exception and wrap an inner exception like:
Dim con As New OleDbConnection(My.Resources.ConnectionString) // Give exception = Format of the initialization string does not conform to specification starting at index 62.
When I substitute the actual value of the Resource, it give no exception :
Dim con As New OleDbConnection("Provider=Microsoft.ACE.OLEDB.12.0;Data Source=C: awData.xlsx;Extended Properties=""Excel 12.0 XML;""")
i have a card number and i convert it into hexadecimal. After that i wan to set the format to 6 digit if the hexa card number has a length =5. so how i'm going to set the format?
Why would anyone use String.Format in C# and VB .NET as opposed to the concatenation operators (& in VB, and + in C#)?What is the main difference? Why are everyone so interested in using String.Format? I am very curious.
I am receiving this error message: "Input string was not in a correct format." on my ASP.net 2.0 VB project.
When looking at other posts with this error its obvious that each time it will be specific to the users' project. Therefore my main question is, is it possible to generate a more informative error message?
I am already in debug mode but it does not tell me in which string the problem lies. I am converting some strings to integers with "Cint" and have also tried the Integer.Parse() method to no avail.
