I generated 10 integers in the array(9). Then I separate the array into two parts by using substring. But I just can't run the code, it has no error but cannot run.

is it a bad idea to create separate parts/winforms of the same application (using the same SQL Server DB) in different executable files. For example for a School IS: A Receptionist App, A Teacher App, A Principal App and so on.

View 11 RepliesI have a Comma Separated value file in .txt format... simply put, its a bunch of data delimited by commas and text qualifier is separated with ""For example:
"So and so","1234","Blah Blah", "Foo","Bar","","","",""
"foofoo","barbar","etc.."
Where ever there is a carriage return it signifies a new row and every comma separates a new column from another.My next step is to go into VB.net and create an array using these values and having the commas serve as the delimeter and somehow making the array into a table where the text files' format matches the array After that array has been created, I need to select only certain parts of that array and store the value into a variable for later use.... how to make the array and selecting the certain info out of it..
I seem to have a problem here. I need to be able to delete a certain part of an array. For example, this is the array
Array(0) = "Test"
Array(1) = "Test2"
Array(2) = "Test3"

I have a large matrix, aprox 600x300 and want to divide it up into 6 sections across and 4 vertically and then sum the corresponding areas of the large matrix based on this division. To clarify all the numbers in the top 100 x 150 area of the matrix would be summed to give me the first number in the next matrix. I've tried playing with some code but its not giving me what I expect and I'm unable to figure out exactly why. I'm sure there is a more efficient way to do this but I'm unable to find it.
Array1 - original large array
Array2 - new small array
y and x count are the new coordinates of the new array

I normally place all db related work in my databases in SQL Server Express 2005. But in tutorials I have seen, I heard that one needs to re-create referential integrity and relationships and constraints and checks and defaults anew in datasources mapped onto databases. Is this true? What parts of a database are NOT mapped on to datasources?
View 2 RepliesI'm trying to create a valid RegEx replacement pattern for correctly formatting specific .XML file names. Specifically, if a file name does not begin with a prefix, let's say, ACE_. If the XML file name and extension does not begin with ACE_, prepend the string ACE_ to the file name.For example, if my input source string is the following:
Widgets.xml
I would like to execute a single RegEx Replacement that would result in the string being:
ACE_Widgets.xml.
Conversely, if the string already begins with ACE_, I would like it to remain unchanged. Also,how can I include the pattern ".xml" to ensure that the string pattern for the file name and extension ends with ".xml" in the same matching pattern for the RegEx Replacement pattern? As for the match, I have some luck with the following:
^ACE_{1}[dD]+
Which indicates there is a match for the pattern if the input string is ACE_Widgets.xml and no match if the string is Widgets.xml
The RegEx pattern would suffice, but if you need to know the language in which I'd like to use the replacement pattern is in .NET 4.0 in either C# or VB.NET.

I need to separate each value and put it in an array. typically it would be done by ".split". however I need it to be split in this order: 0, 50, 100, 200, 400 etc.. In other words, I need it to read the rows left to right. I have no problem separating each number, I just need it to read it in the specified order. I've tried the regexp and I forgot to mention that after each line there is a line break. I am not sure if this would impact the regex, but in any case, after i do the regex, I get the following order: 0, 6.65, 84..??, 35.... etc
I am not getting the order I need as stated above
Expected results: 0, 50, 100, 100, 200, 400, 218, 9.8, ???, 6.65, 6.31 etc...
I am going to follow some of the suggestions below by splitting up the string into separate lines initially. this code almost does that:

I have a TabControl object on my form with many tabs created in code (TabPages) and my problem is that the same objects that are in the initial TabPage needs to be in the other TabPages created in code, I have this done in code when the user clicks the 'New Tab' menu option, however the same code is used for any new tabs created. The problem created here is that I have an event against one of the objects that appear in the other TabPages, but because the same code is used to create any new tab pages, the event will only work on the newest tab page, if that makes sense? By the way these objects that appear on the other TabPages are properties at the top so events can be handled against them in the respective subroutine.

I'll get straight to my problem - I'm currently coding in Visual Studio.I have a table (countries) with the columns ID | Name. The table is filled with around 28 records.I also have a form with 4 combo boxes (set up as 1,2,3 & 4) that I want the user to select. These combo boxes will display the names from the table countries. I then want to use the selected names in the combo boxes to Insert into their corresponding ID into another table. For example England would have the ID 1, USA the ID 2 etc.So, is it possible to have separate combo boxes that will give separate ID values but using the same table? At the moment I can't seem to find a solution.Eventually the form will have more than 4 combo boxes so I don't want to use separate bindingsources for each combo box.
