I currently have a very long column (5,000+) of which a lot of cells start with a range of zeros which I want to get rid of (the zero's that is). After importing the data from a txt file, I have a loop going through each row in turn getting data from different cells. So I could amend when teh data is being imported or during the loop reading the data.

I've got an issue with a program I am writing. The specific issue is replacing characters in a parent string by finding, and matching, specific characters within it that are parsed from an external xml file. It's for a chat-like client.Here's the 2 classes I am using to pull the emote strings, titles, and id from external XML:
Imports System.Text.RegularExpressions

I am writing a Macro for an Excel spreadsheet that copies cells out of a separate file and pastes them into the open workbook. Some of these cells contain the error #DIV/0. I need an if statement to replace all copied cells that have the error #DIV/0 with the value 0.

I am working on a program and for one of my features, I need to replace all spaces in a program with - (dashes.) Is there a way in which I can do this?
Example:

I've got a string which could or could not contain the substring "/announce". I would like to replace this part of the string with "/scrape" if its found...so far nothing tricky. But heres the thing: I only want to replace it if the '/' in it is the last occurring in the string. Heres what I mean:
Heres a scenario where I want the replace to happen:
MyStringWithRandomText/announce?x=19
would become:
MyStringWithRandomText/scrape?x=19
And heres another scenario where the '/' in announce is not the last '/' occuring in the string, so I dont want to replace it:
MyStringWithRandomText/announce/foo?x=19
I hope that made sense. Not sure if there is a way to handle this by only using RegEx
I have a binary file. If I look at it with a hex editor, the first values are:208, 207, 17, 224, 161, 177, 26, 225, 0, 0, 0, ... etc.It has a length of 330240 bytes I have tried to open it and read it into a string so I can manipulate it and write it back. No matter what I use, I either don't get the correct number of bytes or the values in the string are incorrect. The most common error results in the first values being: 63, 63, 17, 63, 63, 26, 0, 0, 0 .... etc.It is interesting that it appears that any value > 63 becomes 63.
I get the 2nd values by a simple loop:
For lnx = 0 To 99
Debug.Write(Asc(line.Substring(lnx, 1)))

I have tried a whole number of ways to read in the file, including filestream, My.Computer.FileSystem.ReadAllText, File.io.readAllLines, etc.All either give me a string length of about 324000 (not sure why) or, if they do, don't have the correct values. Yes, I have tried various encoding options.
I need to find a string (sort of like: "D" & Chr(0) + "L" & Chr(0) + "S" & Chr(0)... ) so I can then replace that portion of the string with a new value, then write out the file.I use the ".indexOf" to find the data in the string.Why can't I load the file into a string? Or, do you know of an easy way to find some text (similar to above) in a file and then replace the next x number of bytes with a new value and close the file?
when i copy code from vb.net code window, and paste it in my richtextbox, the color synthax is as it displays in my vb.net code window.. this i want to keep when finding and replacing words. i have the following code to find and replace,

but the color syntax of the richtextbox code is lost, looks like a textbox's text.. how do i replace the words and keep the synthax coloring?
i'm trying to create a program that is highly edible. Users will be able to change multiple things by just replacing the existing dlls. Kind of like a modding ability. The new DLL shouldn't have to recreate every function though, it should only include the ones that it changes and then hook to the old dll for anything that it doesn't have. Is there a way to dynamically do this? Reference another dll (like a proxy) through yourself for anything that doesn't exist in its self?

I can replace one parameter with one value using string.replace, but how would I continue to process the rest of the string? Would I replace the first parameter then reevaluate the string again to find another parameter until no more parameters are found?
I am trying to do this but it doesn't work:
VB
Dim str As String = "07" & GetBetween("Stephen 0761234567", "07", vbNewLine)Dim op As String = "lol" TextBox1.Text.Replace(str, op)
GetBetween is just a function to match something between something else. That works fine, the string (str) sets as 0761234567 just like I want but when i try to replace the text it doesn't work.
Sorry if this seems like I haven't searched, however I have. Maybe I'm not understanding something or maybe I just haven't found what I need. Anyway my question is this. How would I find multiple strings in a text file and replace them? So far I've been able to find out how to replace a single string with:

View 5 RepliesVB 2010 form has 1 panel, 1 DGV in the panel, 1 TabControl with 3 tabs in the panel each tab has a DGV all 4 bound to the same DataSet through code.
I have a form that has multiple Datagridviews on it, 1 in the main portion of a panel and the other 3 in a tabcontrol. If I click on cell 0,4 of DGV1 cell 0,4 of DGV2 is also "hilighted" and the same goes in the reverse order. If I click on cell 1,4 in DGV 1, cell 0,1 is hilighted in DGV2 (basically it stays with the last selected col and what ever row for that DGV).
This isn't the functionality I'm really looking for here, when I single click or change cells on any of the DGV's I don't want any of the others doing anything.
As you can see there are 2 cells selected this was created by a single click in the 4th cell of Param0
I am using vb.net to parse my own basic scripting language, sample below. I am a bit stuck trying to deal with the 2 separate types of nested brackets.
Assuming name = Sam
Assuming timeFormat = hh:mm:ss
Assuming time() is a function that takes a format string but
has a default value and returns a string.
[code]....
I could in theory change the syntax of the script completely but I would rather not. It is designed like this to enable strings without quotes because it will be included in an XML file and quotes in that context were getting messy and very prone to errors and readability issues. If this fails I could redesign using something other than quotes to mark out strings but I would rather use this method.
Preferably, unless there is some other way I am not aware of, I would like to do this using regex. I am aware that the standard regex is not really capable of this but I believe this is possible using MatchEvaluators in vb.net and some form of recursion based replacing. However I have not been able to get my head around it for the last day or so, possibly because it is hugely difficult, possibly because I am ill, or possibly because I am plain thick. I do have the following regex for parts of it.
Detecting the parentheses: (w*?)((.*?))(?=[^(+)]*((|$))
Detecting the square brackets: [[(.*?)]](?=[^[+]]*([[|$))
I have a DataGridView. I'd like the user to be able to select multiple cells using ctrl/shift. Then, as they type, I want the contents to update in all the selected cells. I'd prefer it if this happened as they type but I'd live with it updating the other selected cells when they leave the current cell.
I've tried hooking in to various events to to this but in each case there seems to be one problem or another that stops me doing it.
I want to know how many cell a namedRange contains . or want to check either a named range contains a single cell or multiple cells.
View 2 RepliesI am experiencing something very bizarre when I execute the Fill method of my adapter. I've been running this query for months and all of the sudden this is happening after I installed SP1 for Visual Studio 2008. For some reason several DataRows in 2 of the 3 tables within my DataSet have errors in them when I view them in debug mode using the DataSet Visualizer. Here is a picture of what I'm talking about
It does this to random rows. If I execute the Fill method the first time, rows (5-10) will have these errors. If I execute the Fill method again rows 12-23 are affected and so on. I have no idea what is happening here.
This is effected my DataGridViews, because they don't display any rows, because of the erros. I should also note that when I run the lines of code below in the Immediate Window it says the DataSet doesn't have errors.
?Me.ds.Tables("Current").HasErrors
False
?Me.ds.HasErrors

I am trying to write a module that will select cells from multiple, non-contiguous columns within a row that is defined by a variable. The column numbers are known and are unchanging. For example, my worksheet might look like this:
A B C D
Row 1 X X X X
I want to select cells A1, B1, and D1; however, I don't want to use the row number (1 in this case) in my code. Rather, I want the row number to be specified as a variable. The code I am writing is inside a For/Next loop, so I would like to use the iterative variable (i in this case) to define the row number. That way, every iteration of the For loop will select cells from a different row.
I'm working on a simple miles-per-gallon calculator.

Dim count As Integer = 0

This compiles and works for 1 iteration, after many trials and tribulations . What I need to do is make it run for a user-specified number of iterations (the tankfuls variable) and store those separate results in separate locations in the arrays, then average all of those values at the end (find the overall average MPG).
I wanted to make a flow chart with more than 50 labels (see this link for just a small portion of the flow chart [URL]). I looked all around but couldn't find one in VB 2008 with the same problem. but anyway, my questions are:
1. Is there a way to set the color of all the labels instead of just one by one say:
Label1.BackColor = Color.FromKnownColor(KnownColor.Control)
Label2.BackColor = Color.FromKnownColor(KnownColor.Control)
Label3.BackColor = Color.FromKnownColor(KnownColor.Control)
...
...
...
There should be a way to loop through them
2. Is there a way for search through the Labels and find for example Label14? or a label with tagindex of 14? I rather be able to find label 14 but the tag also works.
3. Is there a better way to represent flow charts and stuffs like that in VB 2008?
At my company, product is boxed and then placed on a scale/label printer set up in order to be weighed and labeled. The application running on the PC also records a record of each box in an MS Access Database which is then transferred to the main server. There is a separate access database for each scale PC and currently the only way our shipping department can print out a manifest for each pallet (which contains a list of all the boxes and their weights) is to open the correct access database and print out the report by entering the pallet number. Since there are six printer scales and the shipping person has no idea which scale it will be on just by looking at the number, she has to find the correct database through trial-and-error.
What I've been asked to do is create an application where she can simply type in the pallet number, and it will search each individual database for the number, then open the correct one where she can then print out the report without having to guess where it is. I've already figured out how to make the application open the database and report, but I don't know how to make it find which database the pallet record is contained in.Basically I want it to search a number of databases for a particular number in a field, and the return a value when it finds it of which database it is so that I can plug that in later. I have no idea how to do this and my searches online have proven fruitless.

I am finding specific words in the RichTextBox (in this case, "Hey!") and selecting them by getting their initial position through the "Find" command. Unfortunately, this does not work when I have multiple instances of "Hey!" in the RichTextBox. Here's an example:
Text in RichTextBox:
Hey! This is cool!
The Find command would return a value of 0 in this case. However, let's take a look at another scenario:
Text in RichTextBox:
In this case, the Find command would return a value of 0 again, but I want it to get the initial position of the second "Hey!" statement. I'm wondering how I can do this.
My main goal is to have an excel spreadsheet that automatically plots the overall success of my stock portfolio over time (% change over time). I've been able to incorporate stock data into my spreadsheet by linking it to the web, but the trouble is the spreadsheet will keep no history of what the previous stock values were, so I can't graph how things change over time. This sounds like it might be too complicated to be built in to excel, so I was wondering if anyone knew how to program this in Visual Basic. Maybe something like this.... If refresh then new cell plus new time stamp. Another possibility would be to have a whole bunch of cells that refresh only once but at longer and longer intervals, e.g.,

View 3 RepliesWhile my user is typing text into a textbox i want the characters " to be replaced with ' '. The thing is, when i put ' ' in the replace code, it thinks it is a comment so i cannot run the code without producing an error.Also in my multitext box, everytime i write text and hit ENTER, save and then load it back again, the last line ends with a comma, so:
Line 1
Line 2,
When the text is written to the file i read from, it will show like this:

So i need a way of trimming ", when the apostrophe " and the comma , are together. My code already trims "".
