I've made a little map-maker for my tile game, which just stores a single digit for each tile. The problem I've noticed, is that when I save a digit, it tags a space on the end of it, so that when I read the file I have to read every 2nd character.... plus ofc it makes the file twice as large. Is there a way to trim the space from my digit when I save it to a text file?
View 11 RepliesI just changed a control on a form from a masked textbox to a normal textbox because I wrote my own code to validate the data. I'm trying to clear the leading spaces that were created for this column in an Access database using the LTrim function and it doesn't work for some reason. The column is " :30" in the table and when I LTrim it and save the changes, it's still " :30" , not ":30". Is that leading entry not a space character?

View 4 RepliesI'm reading in an xml file, which is working fine with no problems, but I want to re-format one of the elements data attributes slightly.
The XML attribute output is currently Wind: NW at 6 mph
What I want to do is extract just the number from the string, I figured an easy way would be to simply play with the length of the string and assign it to another variable.
However, I've ran into a little problem.
I can use windRtrim = wind.Substring(0, wind.Length - 4) (Where windRtrim is the amended string variable and wind is the string from above)
This returns Wind: NW at 6
Which is great, but the problem now is trimming the correct number of characters from the beginning of the string as it'll be different if the number were to go over 9 (ie. 10 and above)

Is there any way to create a login form that grabs info from active directory, and based on the group you're in, the correct tabs will appear on the form. For example if you are in the domain admins group, that tab will appear, if you are in the helpdesk group it won't show.

View 4 RepliesI've got an unusual request. I have an image that will always have bounds that are of Base 2 (2, 4, 8, 16, 32, 64,...) in both dimensions. I need to know if there's a way that I can get a small 16 x 16 square (or smaller, still of base 2) portion of the image. I'm planning on overlaying a grid on this image that way the user can select a portion of it and then the program creates a dynamic image from the selected grid square to use. Is this possible to do? I did a quick search on the Image class and didn't see anything that stood out. Note: This is for framework 2.0, but not picky about jumping to 4.0 if necessary.
View 8 RepliesI have an array filled with values from Excel cells. Each of the values is a concatenation of two things separated by a pipe, like "Machines|MachinesCode"
I need to, as I fill this array, strip out the pipe and everything in front of it so that the array being filled is only filled with the "MachinesCode" part of the cell value, but I haven't had much luck finding how I should do this. Each cell is dynamically filled and will never have a set length, so I can't set a trip by a particular number value of characters in the strings.
This subroutine is what I'm using. I am filling array FieldArray with another array (ExcelArray) currently holding the concatenated values.
Public Shared Sub PopulateFieldArray(ByRef FieldArray() As String, ByVal iFieldCount As Integer, ByVal ExcelArray(,) As Object)
Dim iIndex As Integer
For iIndex = 1 To iFieldCount
FieldArray(iIndex) = CStr(ExcelArray(2, iIndex))
Next
End Sub
But I don't know what to wrap around the CStr Excel array to cut off the pipe and all values before it while I fill FieldArray.

I have a large tab delimited text file to process each day (usually around 25 mb) consisting of usually well over 100,000 lines. The file is actually made up of about 9 or 10 reports separated by "END OF REPORT". I'm wanting to write each individual report to it's own text file. Some values may have trailing spaces or even contain nothing but spaces, so I am wanting to trim those to only the data, or be left with null. Ultimately each report will be imported into sql server tables. The code I have below runs successfully to completionwithout error although each text file is empty. The script is also extremely slow and seems to use quite a bit of memory. The arguments are ad

View 39 RepliesI have a website that has highly granulised access and hence requires many web.config files. The problem is I would like to trim the menu so that only certain users will have access to certain folders. I have enabled trimming and setup roles in the sitemap, however when I access the page the menu is not show, as I am authorized to view the default page which is not in a subfolder. When I type the url of a page in sub folder's I have access.
How should I handle this:
A site map for each web.config file - don't know how this will work Removing the sub web.config file to only use a single one
I have a list of strings. For each string in that list, I want to prepend another string. I wrote a method to do it, but I was wondering if there was something already in .NET I could use to do this. It seems like something that could be built in, but I was not able to find anything.
Here is the method I wrote:
Private Function PrependToAllInList(ByRef inputList As List(Of String), ByRef prependString As String) As List(Of String)
Dim returnList As List(Of String) = New List(Of String)
For Each inputString As String In inputList
returnList.Add(String.Format("{0}{1}", prependString, inputString))

It works, but I would rather use built in functions whenever possible.
I'm migrating from VB6 to VB.NET, in hence my questions below:
I have to write a function that returns array of strings.
How can I initiate it to empty array? I need it since I have to check if it's empty array after it returns from this function.
Is list of arrays better for this purpose? If I use a list - Is it empty when it firstly defined? How can I check it it's empty?
I have been looking for examples to find the string between two strings. This top one works fine;
Public Sub ReadData(ByRef keywordStart As String, ByRef keywordEnd As String, ByVal filename As String)
Using reader = New StreamReader(filename)
[Code].....
Now the first one is fine - Ext_Volume is result of the string between the strings <Volume> and </Volume>. <Volume> and </Volume> are unique so this is straight forward.
However the second one - "^FDExp:" is unique, but "^FS" is not unique. There are occurances of "^FS" before and after "^FDExp:".
How do I get the string to search AFTER the occurrence, not before etc?

View 13 RepliesI have a DataGridView that has some columns with dates. It binds to an in-memory Datatable which gets loaded from an string array of data passed back from the backend Some of the rows returned have nulls for the date columns. Solution 1: If I define the Date column in the DataTable as "string" I can easily convert those nulls to empty strings and display it in the grid as empty strings (desired results). However, if the user clicks on the date column header to sort by date, it doesn't order the rows as you want. You get a purely string sort order. Not acceptable

When I'm writing comments in my code, I often forget to add the initial space after the comment identifier.
'this is a comment
when really it is supposed to be
' this is a comment
I realize this is quite trivial, and you could simply say "just add the damn space you idiot", but I'd really like to automate this so that I just don't have to worry about it. add the comment space?note I do realize that a catch all string replace or regex replace could screw up other things ... IE:
Dim something As String = "I'm a nerd"
would actually come out
Dim something As String = "I' m a nerd"
if it's only on a line by it's self and is not followed by a second single quote... IE: '' would not trigger the replacement.
