I am facing an issue with my code the thing is i want to escape { in the string.format function Of course one way to escape it is to use {{ (2 curly braces)Is there any other way possible to escape without using the double curly braces.
View 4 RepliesI tried writing the following TestCase for an NUnit test written in VB.net:
<TestCase("FirstNode", "<node id="FirstNode">")>
Public Sub GetNode_GivenSomeNodeId_ReturnCorrectNode(ByVal nodeId as String,
ByVal expectedXml as String)
[Code]....
The xml-node passed as the second parameter to the testcase is not valid however, as this clearly is not the correct way to escape double quotes. I'm sure I can find a workaround in order to check that the method under test returns the expected XML-node, but I'm curious:
Is there some clever way to pass a string such as this, containing double quotes, as a parameter to an NUnit test?
Does anyone know the keyboard shortcut to jump from the start of a For / For Each (or If, While, etc.) block to the end of it in visual studio if you're using vb.net? I found the following which I thought would work but doesn't : Go to Matching Brace in Visual Studio?
Following the comment there I checked Tools/Options/Environment/Keyboard for the Edit.GotoBrace command which is mapped to Ctrl + å in Swedish.Vb.net doesn't use braces per se, but in the following example:
For Each Foo in Bar
Do lots of stuff
Next
I would have thought that the same command should jump me from the For Each to the "Next" but it doesn't do anything. Is there another command (or should that command work but something is broken locally?)
I am stuck in a problem with an application. I have following lines of text :1) hi {my|your|his} name is {stacker|monster|overflow}2) hi {my|your|his} job can be to {stacker|monster|overflow}3) hi {my|your|his} car {stacker|monster|overflow}What I want :on the click of a button select and replace those words which do not have { or } just before or after the word i.e. in line 1 or 3 we do not have any such word. In line 2 we have "can" and "be".

How can I get the curly brackets in sql server? Which is my db in backend.
I am trying to build an application which does the following :
1) write some text in a richtextbox
2) when user clicks a button, the app will replace the text with another text in {} braces.
what I want is that the next time, the regex searches for any text it should exclude those which are present in {}. for eg : my world is good world and a happy world and will be a better world for everyone. first pass - change word "world"

I need my application to do some fairly simple C-style curly brace text parsing. The text style is similar to C or C# in that it uses curly braces to define blocks of code.[code]As you can see it also uses C-style comments (//) and can (actually always will) use nested blocks, but only up to one level of nesting is allowed. As you can also see, the code does not have to be formatted neatly. There can be spaces before any opening or closing brace and it will still be valid.The text however is not similar to C or C# in a few ways:
- it does not need a semicolon ; after each 'statement' (abc, def)
- the block names will always consists of one single word except for the possibility of comments behind that word.
- the event names may contain more words
- the block and event names do not end in parentheses ()
I am telling you this because I have a C and C# parser which I can use (it came with the text editor control I am using) but it does not recognize the language I need as valid C or C#, because the block names do not end in parentheses, and the commands are not ended by semicolons. Therefore it keeps doing things wrong (it should automatically outline the text, auto indent it, smart format it etc) because it is expecting C syntax exactly, and it sees my language as loads of syntax errors (missing semicolons etc).So, I need a way to parse the language manually, and it needs to be pretty fast too. Some of the things I need include:
- Getting an entire block (including nested blocks) just from the block name (identifier?).
- Getting all block names (nearly had this working with the help you guys gave me but not completely there yet).
- Getting all event names in a specified block.
- Getting an entire block (or just the block name) just from the current cursor position (if the cursor position is somewhere in block2 I should be able to identify that and return 'block2').
- Probably more...
Then I thought, wait a minute, this C-style language is probably the most used language style, so there should be LOADS of examples online... So I started googling but did not find many relevant things.Is there anyone who has any knowledge about simple language parsers? Anyone who can help me do the things I wrote above..? I realize I am asking for a lot, but the language is pretty easy and I cannot imagine that it is extremely hard to parse it quickly. I also don't require any syntax error checking; all I need are the few things above (mainly retrieving the block names and event names).
I have written a quick 'algorithm' that automatically formats curly brace code in the correct way:[code]It works quite simple, it loops through all the lines and keeps track of the brace count using a counter. The counter will be incremented by 1 if it finds an opening brace, and decremented by 1 if it finds a closing brace.Then, each line is trimmed, and a total of "n" tabs is inserted before the text, where "n" is the brace count as explained above.[code]So my question basically is, how can I avoid having to do the same thing (exchanging lines) twice? I have noticed that the actual exchanging of lines is very slow, so having to do it twice for each closing brace line is simply a very bad design..
View 6 RepliesI have a situation where I am handling both single & double mouse click events on a form. In both cases something has to be loaded, however when a double click occurs, I do not wish to execute the code attached to the single click event.Is there a way to intercept the mouse click's and check if double or single and then execute the right event appropriately?
View 2 RepliesI have a htpc project that I am working on. The main program loads dll plugins which are basically other win forms. On each of these forms, including the main program, I use a picturebox (a double buffered picturebox) for the background image and then draw everything on it by hand. Whenever I load the form from the dll and show it, I get a weird flicker. It looks like it is the previously used double buffer. Is there any way to clear the background double buffer before the flicker? Or am I going in the wrong direction?

View 6 RepliesI want to do the equivalent of the following VB in c#
Function([class]) "hello"
This would be the same as this in c#

The problem is that the word class is a key word in the language. But I want to use it as a variable name. In the VB example you can use the [] brackets to 'escape' that key word and allow it to be used as a variable name.

I'm trying to track down the cause of an annoying interface bug in an app that was ecently upgraded from VS2003 to VS2008 (the bug did not exist pre-migration).What happens is this :1) User clicks in textbox containing a date.2) User clears date3) User tries to move to another field, but can't. No error messages appear - it's as if the validation failed.Further info :1) The textbox's Text property is bound to a dataview which uses a datatable as its source. The bound field is a nullable datetime field with no constraints or default.2) The Validating event fires and the CancelEventArgs property is not set to Cancel. The Validated, LostFocus and Leave events all fire as well, going LostFocus > Leave > Validating3) I can't see any code changes relating to the control or the datasource with a couple of exceptions. The first is that this :
Me.txtRangeEnd.DataBindings.Add(New System.Windows.Forms.Binding("Text", Me.dvClientNos, "RangeEnd"))

I have a couple of strings (in Ms-Word) which I copy and paste into variables in visual studo. Ms-Word uses high ansi characters for double quotes ("x"). I need the same in my app too. There seems to be no easy way to do this.
1. Visual Studio converts them to simple double quotes ("x") if I let it format the line automatically (auto-indent/auto-format).
2. If I turn autoformatting off and put those characters, I can see the correct characters in the code in Visual Studio editor. But when program is run the behave same as the simple double quotes. They are treated as simple double quotes and converts to simple double quotes in the output.
The only way I could find out is to use Chr() etc. functions to concatenate the character codes at appropriate places. But that's tedious on large strings. I want something to escape these characters appropriately (just like we can put two double quotes to escape the simple double quote character). [code]
1. What is the correct way to escape these characters? I don't need string concatenation; I need it in one string (like x="abc").
2. Are there any other characters also which visual studio messes up?
For displaying the character & in a button as text, i am using &&
I would like to display the string % in another one button but the &% does not work.
So how can i display the char %
By using this btn5.Text = "%" the percentage symbol is not displayed at all!

If I needed to escape a double quote character within a string literal I'd use two consecutive double quotes as follows:
Dim name = "Chuck ""Iceman"" Liddell"
However, it doesn't seem like consecutive # works the same way. The compiler is expecting a compiler directive to follow the # character, even when its enclosed in double quotes. How can tell the compiler that I want a # character in my string?
EDIT: as a few of the answers below point out, # is not a reserved character. I closed my solution in Visual Studio and re-opened it and no longer got the compiler squiggles warning me.
