Make A Function That Will Return The Name Of Selected Report?

Mar 22, 2010

I need to make a list box with 2 reports in it. Then i need to make a function that wil return the name of selected report, or if no report is selected then return "no report selected".After i made the list box i tried to make the function in the code builder: insert procedure -> function. I tried using an IF statement to make it that when a report is selected the report shows as in a msg... but it keeps saying something is wrong with my code.

C# - Make A Function With Return Type Generic?

Apr 29, 2010

Currently I have written a function to deserialize XML as seen below.How do I change it so I don't have to replace the type every time I want to serialize another object type ? The current object type is cToolConfig. How do I make this function generic ?

Public Shared Function DeserializeFromXML(ByRef strFileNameAndPath As String) As XMLhandler.XMLserialization.cToolConfig
Dim deserializer As New System.Xml.Serialization.XmlSerializer(GetType(cToolConfig))
Dim srEncodingReader As IO.StreamReader = New IO.StreamReader(strFileNameAndPath, System.Text.Encoding.UTF8)
Dim ThisFacility As cToolConfig

Make Function Not Generate 'doesn't Return A Value On All Paths' Warning?

Oct 22, 2010

I 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]

Return An (Anonymous Type With A Function) From A Function?

Mar 3, 2011

Just 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)

Word Report Carriage Return Using Asp.net

May 26, 2011

I am generating report in word(i.e) I am exporting all the data from the database and replacing it in with the placeholder in the word document. While the data is being retrieved from the database if the data contains any enter or new line character it retrieves it with the boxes and hence it replaces the string in the word with boxes such as for eg. abc and then box icon and then xyz on other line for abc...xyz text.how can i eliminate the box icon and still display the data as above? I have tried replacing the character using chr(11), chr(13), system.newline etc but the box icon still exists? Is there any other way i can perform the above task?

When a user starts to type in and the AutoComplete does not find any matches in the listitems the user can tab out of the ComboBox and leave what they typed in the combobox even though it is not one of the Valid Items. Is there a way to check the Comboxbox to make sure of of the selected Items has been selected?

Run Through Selected Path And Return Results To Array

Nov 20, 2009

So basically, I am running through my selected path recursively and returning the results to an array.. I think.
vb.net
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim path As New FolderBrowserDialog
If path.ShowDialog = Windows.Forms.DialogResult.OK Then
Me.TextBox1.Text = path.SelectedPath
[Code] .....

I was told that to return the search to an array, I add the return toarray() at the end.
Now obviously Im not getting errors, but I am also not polling the results that are in fileslist.toarray(). I've looked at arrays quite a bit, I see their functionality if they are defined like myarray(4) with 5 declared array values... its an array with 5 value places. And to read from any one of the 5, you'd say something like msgbox(myarray(3)) to call the 3rd place in the array.

Well, as you can tell from the code, I am putting a variable amount of information into the array, How can I call that information? If I scanned a folder with 300 files, how can I call the results of that array and put them in a text file, or console, or messagebox through them? And assume I am doing it through a button click event. So, button click to read all input in the array to console or something like that.

Forms :: How To Return Selected Values To Custom Control

Feb 17, 2011

I'm learning .NET and I've got a question about user controls. I'm using VS 2010.. I've created an user control, which contains a textbox (code), a button and a label. When you fill in the textbox, the system searches of the codes exists, if so, the description is showed in the label, else it's cleared. When you click the button, a form opens with a datagrid where you can select a code. When you select a code in the datagrid, the code textbox should be filled in with the selected code. How do you return the selected value to the custom control? I've created a public property in the custom control, but i can't access it.

Function Does Not Return Nothing?

Feb 12, 2010

take a look at the following Code:

Private Sub btnDebug_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnDebug.Click
Dim d As Date

[Code]....

The Funtion ZZNull always returns Nothing, so IsNothing(d) in the calling method should evaluate to True.

But it does not !

When you run these lines, then you will see that IsNothing(d) evaluates to False

How To Use A Function's Return Value

Mar 8, 2009

So 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

[Code].....

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, 2010

I'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
Dim lngFinal As Long

Print Selected Pages From A Multi-page PrintDocument1 Report?

Nov 10, 2009

I have a data-driven many-page print system that works well, each page containing logically what's next following the preceding page. To output a sub-set of pages, how can I avoid outputting pages before the first one that I actually want to send to the printer? To pick and assemble the data correctly my PrintDocument1 process has to run until I reach the 1st page to print, so it would be neat at the end of each unwanted page to 'waste' them - then from the 1st wanted page the usual e.HasMorePages will do the job.

I thought maybe PrintDocument1.Dispose() or PrintDocument1=Nothing might void the early pages I don't want (then looping back internally to construct the next page), but no. Is there another way to 'ditch' pages until the required one is reached? Or do I have to avoid using every e.Graphics.DrawString) statement until I get to the right start point? That would of course do the job, but is pretty clumsy

CLR - Function/Operator Without Return Value?

Sep 4, 2009

I'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.
