Replace VbLf And Chr() With Constants?
Mar 18, 2009
We're trying to trim the number of assemblies we load during startup, and one of the easiest to cut is the Microsoft.VisualBasic assembly. There are alot of things in it that were easy enough to replace, like Left(), but I'm struggling to find a good way to replace vbLf and Chr(). vbCrLf was easy enough to replace with Environment.NewLine, but we have a few spots where we generate content for a Unix-based system that is expecting line feeds only.

What does vblf do? I have a piece of code from someone else and it has a string that looks like this.Dim Iam as string = "hot" & vblf & "cold" & vblf & "even colder" & vblf & "a bit warmer now"How can i use a string like this? Is it some kind of array? How can i get something from a specific position?

I am calling this function when a button is CLICKED and received the error; The name "The" is not permitted in this context. Valid expression are constants, constants expression, and (in some contexts) variables. Column names are not permitted. Unclosed quotation mark after the character string 'True)'.
The function is as follows;
Private Sub Save()
Dim conn As SqlConnection = GetDbConnection()
Dim query As String
Dim cmd As New SqlCommand

If I take the following XML:
<security>
<user>user</user>
<password>pass </password>
</security>
and call the Trim() method on the InnerText of the password node, it Trims it properly, but If I modify the fragment to look like this:
<security>
<user>user</user>
<password>pass
I can't get the Trim() method to work, pass with the spaces removed is return as pass (It has a single space at the end). I looked at the watch window and when I doubnle click the value, it shows it as:
"pass" & vbLf & ""

I am trying to create a viewer for files with large (sometimes over 2,000 characters) records. I want to use the rich text box control and show a given record in rows of 100 characters each. I have set the font to Courier New and sized the RTB appropriately to show the records correctly. However, if there is a record with 80 consecutive alpha characters followed by a space, then 120 consecutive alpha characters, the RTB separates the line at the space, as if there were a vbLF there. This happens in other cases, but I haven�t been able to figure out how the RTB decides when to break the line.

Say I have some constants that depends one of other, and I decided to keep them together in a container instead of keeping it as individual constants in a class.I thought use a Structure for that scope, but compiler force me to declare a private member for that structure.

i was concerned if constants take up storage. if a class had 10 integer constants at class level, will that adds up to 40bytes of storage or is that actually not true because they are constants?
what i'm trying to do: find the best place to put the constants that i need to access at class scope, and whether its best to make them shared or not. [constants are private]

The file reads in parameters and two of the parameters used to be in Date Format YYYYMMDD but will now permanently be in format YYYY-MM-DD. This change, I believe, is stopping the import of the file from working. I would like to replace the new format YYYY-MM-DD back to YYYYMMDD in the code. If possible I'd also like to see some output so I know that the old format has been replaced with the new format. The code is below. I added the two rows with .replace code in green in expecting that to be enough but it is still not working.
Public
Sub Main()
Dim R1, O1, P1, C1, strDateFrom, strDateTo, strRunDate

String

Every time I do something that ends up using windows API calls in VB, I always end up having to look up the values for the windows constants. Does anyone have a file with a class or something for VB that defines all the WIN-API constants?

I have two list boxes that have a list in each and each one has a constant. I am trying to add the selections that are made together and output the total in a third label. I am stuck at this point and am not sure how to proceed, it is entirely possible that i am doing it wrong. Would someone please have a look at this and let me know what the next step would be or if there is a different wayof doing it than I am.[code]...

It would be good if visual basic had standard math constants like pi, the Euler number, and others built-in so one doesn't have to define them each time and have the possibility of making typos. Even some of the physical constants in MKS unit could be included like the Boltzmann's Constant, speed of light, permittivity and such. Each could be a special simple like kb for the Boltzmann's constant. Or it could be a properties like phyconst.c for the speed of light, phyconst.kb for the Boltzmann's, phyconst.sb for the steffan-Boltzmann's constant, pmathconst.e for e=2.71.

Calculate and display the total cost of the sale, as well as the total cost of all sales and the average cost of all sales. - Clear the box for the number of yards, the total cost, and return the quality, padding, and installation settings back to their defaults. Use constants for the cost of each quality of carpeting ($4.95 for Fabulous Flat, $8.95 for Precious Plush, or $12.95 for Super Sculptured), the padding charge ($1.25 per yard), and the installation charge ($3.50 per yard).

I've got a situation where I need a table of constants in my app. It's actually a table of 43 formatting options where the description will appear in a drop down and the detailed settings will be used by the codeIt appears that VB can't do arrays of constants. So I've fiddled around with a Constructor in a class that creates a new array then loads up each element with hard-coded .Add statements. It doesn't seem elegant though.So I then decided to try an XML file, that I load in the Constructor and assign the contents to an array. This is what I've decided is the best, most elegant, option - but I'm throwing this question in to see what you people might recommend ! The data is mostly strings

The code underneath works when I use WM_MOUSEMOVE but not when I use WM_NCMOUSEMOVE. Is WM_NCMOUSEMOVE not supported anymore?I use the correct values for the constants too.Protected Overrides Sub WndProc(ByRef m As Message)Dim MousePosition As Point
Select Case m.Msg Case WM_NCMOUSEMOVE MousePosition = New Point(m.LParam.ToInt32())
If MousePosition.Y < 50 Then CloseButtonState = ButtonState.Flat
Else
CloseButtonState = ButtonState.Normal

I am exporting data to an Excel spreadsheet from a VB.Net 2008 application. Now I'm trying to format the spreadsheet. So I am creating macros in Excel that format the spreadsheet, and then using the code it generates in my application. The problem is that the constants used in VBA are not being recognized in VB.Net (They are recognized in VB6). I have the following imports:
Imports Microsoft.Office.Interop
Imports Microsoft.Office.Interop.Excel
Is there something else I should be importing? For example, in this line, xlNone and xlDiagonalDown are flagged as not declared.
oXL.Selection.Borders(xlDiagonalDown).LineStyle = xlNone

I have a bunch of object variables which are all initialised in their declarations such that:
Private _myObject As New ThisObject("SomeString")
where ThisObject is one of a number of object types, but all are initialised using a string.
I would like to use the Visual Studio Find/Replace dialog box to search for "As New" then replace everything from "As New" to the first set of speech marks with some text such that:
EDIT
My original example could be solved using other methods. This example is more representative of the actual problem:
Private _myObjectA As New ThisObjectA("SomeString")
Private _myObjectLongName As New ThisObjectLongName("SomeString")

I am trying to think of a regex replace to replace double quotes with nothing. Example:
hello("hi there") would become hello(hi there)
"hi" would become hi
"example "3" would become example "3
-edit Maybe an easier way to explain this is, replace all " that do not have a backslash before them.

I have an app that I have been recoding in vb.net formerly written in VB6. In this app I use some ASCII control codes such as ACK NAK ENQ US RS EOT. The VB6 app uses the CHR() function with the proper ASCII codes to handle these but in recoding I would like to use something more meaningful and descriptive than CHR(4) for example.

In our VB.net coding project, we have a module with the code shown below. In our frmMain.vb, we use every thing you see in the modeul.
However, when happily coding along, intellisense doesn't seem to see these or pick them up.
How can we change this so Visual Studio's Intellisense picks up our constants? For example, when typing:
If System.IO.File.Exists(SERVERS_CONFIGURATION_FILES) Then
I want to be able to type something and then the dot, such as Me.whatever and have it picked up. Below is our module:
Module ConstantsAndEnums
Public Const PROGRAM_NAME As String = "Server Monitor .NET"
Public Const TOOLTIP_BUBBLE_DISPLAY_TIME As Integer = 10000
