Make Function Not Generate 'doesn't Return A Value On All Paths' Warning?
Oct 22, 2010I have a function to recursively search through windows (and their child windows) to find specific ones, it works exactly as expected, however it causes "function doesn't return a value on all paths" warning. This is the only warning in my entire program, and although it might be silly, I'm interested in knowing if there is a way to stop this error from occurring, but still allowing the function to work properly.[code]

If Statement Doesn't Return
Mar 22, 2012Am I just being blind or does this If statement genuinely not do what it's meant to.[code]This displays the message box even though textSample is one of the letters. In my eyes that If statement should see that textSample is one of those letters and skip it, whereas if it was Z it would "Not" be equal to any of those and would therefore show the message box.

Return An (Anonymous Type With A Function) From A Function?
Mar 3, 2011Just so it's known, this question is mostly academic, even though I tried to use the concept in a real-world solution. I realize the example is contrived, but I believe the concept is valid.I want to write some fluent code like this:
[code]...
I realize that I can't force an anonymous type into a specific type (like implementing an interface or some other class), and I don't want the overhead of defining a specific class just to match my desired fluent name with the actual method name. So I was able to make the code work like this:
copy(my_first_file).to.Invoke(my_second_file)So there is no IntelliSense or type awareness there, and I have to include the Invoke in order to have the method run. How can I get more type safety and exclude the Invoke method, under these constraints: Anonymous Type returned from Method No additional classes or interfaces Preferably, I do not want to pass in another parameter to the copy() method that tells what type to return, unless copy becomes a generic method (but I think that means defining another class/interface, which I don't want to do)
Sql Query Doesn't Return Any Results On Datagrid
Jul 7, 2010I'm using Visual Studio 2005, and I have a datagrid connected to a table from an Access database.
I added 4 textboxes so the user can type search filters to search within the table and a "search" button.
Then, I created a query using the "add query" tool on the datagrid. I wrote it like: select field1, field2, field3, field4, field5, field6 from table where field1=? and field2 like "%"+?+"%" and field3 like "%"+?+"%"
and field4 like "%"+?+"%"
Both field5 and field6 aren't search criterias, so I didn't add them to the query. Once the query was created, I replaced the parameters inside the procedure with my textbox1.text, textbox2.text, textbox3.text, textbox4.text and then cut and pasted the whole thing inside my SEARCH button click event, so the query is executed when the user clicks on the button.
Now the problem is: when I search using the first field it goes ok, but when I try to search by any of the other fields it returns zero results, even though I double-checked I had written the words correctly. I don't know why it does this. I already tried deleting the datagrid and creating it again.[code]...

How To Use A Function's Return Value
Mar 8, 2009So the program I am writing validates the controls on the page on button_click.
I want to write a function which checks which step the program is at (0-7) then return something depending on whether or not it validated.
My plan was to return the control which was not valid.
Private Function ValidateInputs() As Control
Select Case wizardStep
Case 0

1. could I return the names off all the controls which did not validate?
2. should I be returning a control type or would something like a string be better?

Return NaN From A Function?
Oct 5, 2010I've created my own version of HexToDec() to properly handle the negative flag. I saw other versions online that used "Not(value)" to do the Pos/Neg inversion, but that does not generate the proper value... No, it's not the most elegant my any means. But I couldn't find anything online that actually worked.
Long story short, I want to return NaN in the case that the function is passed a string that is not a valid hex string...
How do I do that? Everything I've tried generates a compiler error... (assign return value to double.nan, assign return value to non-numeric, etc)
Existing function is below:
Function HexToDec(ByVal hexStr As String, Optional ByVal signed As Boolean = False) As Long

View 2 RepliesWhy Doesn't Function Strip Out Newline

CLR - Function/Operator Without Return Value?
Sep 4, 2009I've create a new project, and set treat all warnings as errors in the compile tab.All the other warnings seem to be treated as errors, except the one which I'm interested in "Function/Operator without return value".I have a simple function within a class, which does not show an error if I do not add a return statement to that function. I have read in many places that VB.Net returns a "hidden" default value if the returns statement is forgotten.My software went out to production where an overloaded function was missing a return statement, which wasn't highlighted due to the above.
