I was fed up of having a duplicate method side by side so merged them into one. Both sent a request to another class.
vb
Private _messageFormats() As String = { _
String.Format(RegistrySettings.PMessageData, Identity, Topic, Body,
[code].....
var queryString = string.Format("filename={0}&filestream={1}&append={2)", fileName, Convert.ToBase64String(b, 0, bytesRead).ToString(), 1);
above line of code giving error 'Input string was not in a correct format.'
I have a function that is getting passed a String and a DataRow.The String is a custom formatter. The idea is to do this
String.Format(passed_in_String, DataRow("ColumnINeed"))
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.
however, i'm copying this directly from the book in its example format and still getting an error.
FormatException was unhandled

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.
View 5 RepliesI want to format the Timespan to have format like this 49 hr 34 mn 20 sec
I used the String format below :
String.Format("{0:00}:{1:00}:{2:00}", theTimeSpan.TotalHours, theTimeSpan.Minutes, theTimeSpan.Seconds)
It formats the Timespan to this format 49:34:20. How can I add hr mn sec to the String.Format above? or there's another easy way?
I have a "Open File" menu on form1 that reads the user input data from the selected file, stores them into variables, passes on the var. to my form2 and loads up my form2 with the user input data. My code works But when I close my form2 and button click form1 to open form2, I still see the same input data I want all my text boxes to be blank.

In reference to this post [URL] I have another more specific question about passing data between forms in VB.net I have a form with over 50 variables that I need to access on a second form and if i followed the method above, my form 2 will end up way too long and time consuming. I'm making a complex calculation software that prompts user inputs values and calculates all those unknown variables. I need to display all the resulting values in the 2nd form. and from the 2nd form , i want to give the users an option to export all those values to an ms Excel sheet.

I need to pass two variables/strings to a background worker at the same time. he background worker needs to return the first variable, and the time consuming boolean result of the second variable.From what I have read, I can only pass an object that contains multiple variables.This is where I get confused
View 1 RepliesI need a nudge in the right direction. I have a user control that has the main form and it calls a secondary form to gather some additional information in some cases. I need to pass the information back from the secondary form to the primary user control form so I can validate the data and save. In the secondary form, I have the following code:
Dim myFrm as new frmOperationComments
myFrm.OperationComments = [comments from form]
myFrm.OperationDate=[Date from form]
I have tried creating two public properties on the user control and setting them, I have created two properties in the user control form called OperationComments and OperationDate. I can set both of them, but when I close or hide the form and go back to the main user control form, the values for these properties or variables are not set. How do you set the values on the main form from a calling form within a user control?
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 sure you've all seen this a lot before (in a variety of forms) but I think (hope) it's a bit different. <Not actual names of variables>I have two forms (form1 and form2). Form1 has 2 class-level variables, a string (m_String) and a collection(colCollection).Inside form1, the collection is loaded using a key. With an if-statement, the collection is matched to input (from a combobox) through the matching key.The chosen string from the collection is then passed to the m_String (confirmed with MessageBox.Show(m_String)
