Reserved Characters When Building XML File From Snipets?
May 25, 2010
I am creating XML files by combining 3 text files; Header contains the start of the XML file, Body contains a repeating section of XML with placeholders that will be replaced for each entry in the database and Footer contains the end of the XML file.Currently I am using Stream writer to create the XML file, the problem comes when the data I am adding in the body section contains reservered characters e.g. > < & etc as the XML will break.Is there a better way? The XMLWriter examples I have seen seem to start from the premise of a complete XML document, which I don't have.
Is there a simple way to remove reserved characters from a string without looping through it and testing each character? I want to remove <>:/?|? from strings that are used for folder and file names.
I'm trying to execute an sql statement in vb.net to an Access database, I am escaping the reserverd word using square brackets []. This has worked in all my SELECT statements within the program.
The reserved word is level
But the SQL statement below fails saying
Syntax error in INSERT INTO statement.
If I directly copy the statement and execute this in Access it works fine
I am running an update sql statement that is returned a bad request error. This is only happening when I'm using reserved words for the field value. I know this happens for table and column names and how to account for that but I've never had this with the actual value.
I'm creating a car class. Make and model are properties but both make and model appear to be reserved words in C#. What's the best practice for naming properties/methods when your preferred name is a reserved word?My first instinct is to call the properties CarMake, CarModel (so a convention of ClassNamePropertyName).My mistake, make and model aren't actually reserved words. VS intelliesense and code coloring made it appear so to me at first glance. Though my question does stand for future reference.
OK I am as green as they come and just want to write a simple app that when it starts loads data into a few fields from the previous use.
I am thinking of using an XML file written to disk to hold this info, (I am open to any suggestions how to do this as simple as possible)
so I am going through the "Wrox VB2010 for beginners" and entering the code to create a class and apparently the compiler doesnt like something about saving stream as a string: It says "Value of type 'System.IO.FileStream' cannot be converted to 'String"

company buy some program(create by VB.net) It's easy for customer install it. in program have SQL Server 2005,crystalreport viewer,.net fremework.. i know only use shell for run exe file, but the program install all automatic, it's set registry and database name for you, you do only click next for install.My boss want to me do it but i don't know how to do.
Where to begin trying to research building a program that can inventory a program and then build a spreadsheet where I can name tabs based on directory names and then color them according to their level in the directory tree. The number of directories and/or total number of files shouldn't be a limiting factor if possible. I would also like all subdirectories to be after the tab for their parent directory.
[1] [1a] [1b] [1b1] [1b2] [1c] [2] [3] [4]
I'm working on a Win 7, Office 2010, and VB 2010 Express machine. The purpose of this is to assist with our data retention policy at my company. I want to split up directories on the tabs to make it easier to search and then employee's can go into certain directories to make files they used for a project so those can get archived and the unused files can be deleted.
I designed an application to download a file from the Internet onto a selected location on the local computer. This application too, has a form-building error.Debug Error Message: An error occurred creating the form. See Exception.InnerException for details. The error is: Object reference not set to an instance of an object.
I am building a program that strips out certain keywords from a much larger file. I am using code that .paul. provided in a different post, but I can't get it to work correctly. Here is the code that I am using: [code] Basically, the first match will appear in textbox2, but no other matches appear after that. I put a breakpoint at the For Each loop and checked out the locals. I am showing 2,502 matches for the variable "match." I just now put another breakpoint in there and I can see that it is stepping, but nothing is recorded.In the archive is a file named debout.txt. This file should be used for the testing.

I am not the original author of this software project and the code is poorly documented. I am mainly a Java/C++ developer.The program displays the tree structure and allows files and folder to be selected. The program is getting errors with FileSystemTreeView when trying to return nodes on a system with a reserved partition.Here is what is happening: tree.SelectedNode = tree.Nodes(0) 'returns error with system reserved partition.calling, GetDriveList() will properly return all the drive letters - and not throw an error. Only when trying to get a tree.Node() or tree.load() is the error occurring.
Working on a small program that saves a file path to a text file and then when run opens the text file reads the file path which will be the only line in the file. I believe I have traced my problem due to the character that would be in the text file when hitting enter to start a new line which I assume is "vbCrLf".
I have a text file coming out of access that I want to ftp to a server but before it gets ftp'd I want to automatically rename the file based on the characters at position 115-119, ie the file will be renamed from 'output.txt' to 'FP002'.
Essentially I am trying to replicate the Windows 7 (In-Windows) activation key TextBox form. The Form where it will auto capitalize letters, remove or deny all non alphanumeric characters except dashes every 5 characters that will be auto-input.I assume this can be done with a fairly complicated replacement Regular Expression but I cannot seem to create one to fit the needs.
This is an Example of what I have right now, but it creates an infinite loop as it removes all characters including dashes, than adds a dash, which changes the text and removes the dash again.
I have a string of text i captured within AutoCAD (0.000000, 0.000000, 0.000000) wich is saved to a text based file named position.txt.as you probably have gatherd with a file name such as position.txt the text could be composed of any random number combination eg: (5.745379, 0.846290, 150.6459046).However for it to be of any use to me I need the captured string to exist without spaces or brackets how can i achiev this in VB.net?
Not sure if too many people know this, but the following line will cause an error:
GroupName.Substring(0, 3) = "jt_"
....if the length of GroupName is less than 3 characters. I always thought it would simply return whatever characters in GroupName, but no, it errors. I must be thinking of the old VB6 days.So, I now have to change the code to:
If (GroupName.Length > 2) Then If (GroupName.Substring(0, 3) = "jt_") Then
Note that the two comparisons need to be on separate lines. If they are on the same line, such as:
If (GroupName.Length > 2) and (GroupName.Substring(0, 3) = "jt_") Then then the code will still fail as the length command is executed at the same time as the substring command- which will cause the error when the GroupName length is less than 3.Just thought that those of us not aware of this should be!
I have two textboxes. I type in one of them and the text gets copied in real time into another textbox. There is one catch. I need to replace specific character with something else.
If I enter a quote " in textbox1, it has to be replaced with " in textbox2.
I started with something like the below code, but obviously this does not work (tried different stuff - this is for demonstration only). In the example below 'a' represents " , and 'b' represents "
Private Sub TextBox1_KeyUp(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TextBox1.KeyUp TextBox2.Text = TextBox1.Text
With the shape of really large characters such as numbers and alphabetic characters + others, is there a way to get that shape as a REGION please?Imagine a really fat snake forming the letter S or two rectangles placed together to form a large letter L or a T like the shapes in TETRIS.
1) Does anyone know of anything in VB.Net that can translate such shapes into a System. Drawing.Region or know of a project elsewhere that achieves this please?
2) While I'm on the subject, how would you SCALE UP / DOWN a System.Drawing.Region please? How would you work out the Transform Matrix required please?
I'm making an application that will change position of two characters in Word.

Program works good, it is mixing characters good, but it doesn't write text to the file. It will write text in console, but not in file. Note: Program is working only with words that are divisible by 2, but it's not a problem. Also, it does not return any error message.
I'm making a custom control suited for handling passwords. I have created a control that inherits from a text box and I have implemented a lot of things so far. But what i want to do now is create a system so that when a user types It will display his last character typed for a X amount of time. Is there a way to turn only selected characters into password characters and still be able to get the password text from the Text property ?
My user can export a ".doc" file but when VB.NET writes to this file it uses "" and "," characters at the end of each sentence. I was wondering if there was a way of actually appending the exported file to remove these characters?
