I have an application in which a streamwriter is used to save values to a file. It all works fine, except I'm curious as to why the values in the file would be rounded. They are rounded with enough accuracy that it doesn't really matter to the app, but I'd like to know why this is happening. My line of code that writes the line is.
View 14 RepliesI am taking in two html files and creating one out of them. To do this I am opening the first html file and not writing out the closing </body> and </html> tag and opening the second file and not writing out the corresponding opening tags, as well as the <style></style>section. I start a streamwriter, and write the lines out to it, and then close the streamwriter. My problem is that the output file is filled with strange characters. I've tried opening the streamwriter with different character sets as the third parm, but all this does is change the characters to different strange characters.It says charset=windows-1252 at the tops of the input files (and the output files for that matter - since I'm just reading stuff in and writing it out - with the exceptions mentioned above).Questions;First, do you think I am properly approaching appending two .htm files together?Second, how can I eliminate these strange characters.

View 4 RepliesI am using streamreader and streamwriter to read a text file , change the text, then write to the same text file. This all happens in a loop every second or so.Currently I use:
Dim csetpointfileread As New System.IO.StreamReader("C:webcsetpoint.txt")and Dim csetpointfile As New System.IO.StreamWriter("c:webcsetpoint.txt", False)before every file read / write operation, it gets dimensioned every loop. To me this seems like a waste, and should only have to be dimentioned once. If I try to run both statements in the beginning, outside of the loop, the second statement wont work because the "file is allready open". Am I missing something or am I doing it correctly to begin with?
building another command-line app and I need to generate a log file and write to it throughout the app's run, but the log needs to be named <work_order>_<device>.log - both of those are held in a text file and will change frequently.
I can extract them no problem, and use them in the log file, but can't get the log file to use them in the name.
so I have:
Using strDATA As New StreamReader(DATA_FILE)
Do While Not strDATA.EndOfStream
Dim eng As String() = Split(strDATA.ReadLine, "=")

PATH and WORK_ORDER are declared as Public earlier on as are PATH, LOG, TMP and CSV, this sub is also Public. I also need to use the log writer in other subs as well as WORK_ORDER and DEVICE.
I have a subroutine that needs to accomplish the following things:
1. Open wordpad (wordpad.exe) - so the user can see the file being written to for printing purposes.
2. Create wordpad file (Sample.wri)
3. Write various text to Sample.wri (in the wordpad window that opened) using Streamwriter. Again, this is for printing purposes.
The code below is the start of the subroutine. As it is written, Wordpad does start, and Sample.wri is created. But the streamwriter DOES NOT write the "does this work?" text to the file created, nor does it display in the window that opened when wordpad process started. I'm new to using streamwriter so I'm sure I've overlooked something simple. The start of my subroutine is below:

View 5 RepliesOnly now, I'm facing this kind of problem, i have a application that until now worked with two different cultures ENG and PT, i always knew this, and i manage to solve all problems related to parsing the numbers, but now i have to change the code, and "protect" the code to handle with others cultures. So i need tips/best way to handle different cultures, and different database culture settings.I think that i shouldn't limit the user, by setting the decimal, the grouping digit, the date time format, etc. . The application should accept the numbers in the user current culture. But this path forces me to putting everywhere the parse/tryparse method.

i need a simple way to get a random number from 2 numbers. This means that for example if my 2 numbers are 3 and 7, i don't need a random number between 3 and 7 that would be like 3,4,5,6,7 but only a random that is either 3 or 7. Meaning not all the numbers between x and y, but either x or y.

All that is happening above is two players are being compared by scores and a winner is then decided. The calculation works fine and places the winner in the correct spot (txtWinner1.Text) as long as the numbers are positive. So if txtU1D.Text has 13 and txtU2D.Text has 14...txtU2 is the winner. Works with no problems. However, if txtU1 has -1 and txtU2 has -2...it says txtU2 is the winner. The negative scores are common in the game being played so the situation often happens, but may be one player only. It seems to work if one is positive and one is negative, but if both are negative it thinks the higher negative number is the winner for some reason. So it will give the win to someone who has -9 over someone who is -4.
I am making a calculator that accepts large number (represented as strings) and performs basic math functions on them. So far I have Add and Multiply figured out.

I saw something like this in the code bank but the examples there were from VB6(?) and were hugely inefficient (compared his Add and Multiply examples to mine, his having way more code and loops.)
How do I add, for example, all the numbers in the textbox (they are separated by spaces)? I tried a couple of methods but no luck so far. So for example, this is what the user will input in the textbox:

Is it a no-no to have a module within a module like I do there? So far there is no mention of such in the book but I can't find an example of it happening yet either? The instructor wants modules to perform the input and return of information and the only way I could figure out it doing both of those things (rather than using the main module for user input) was to call the module that figures hi/lo within the module that asks for the numbers. I'm really unsure on this part.

So I have an assignment dealing with arrays for school but first I will start it off with the simple question as to where I am stuck now. I was wondering what the simplest way is to declare all the numbers in an array without going down the list one by one ( ArrayA(1) = 1, ArrayA(2) = 3 and so on.) I was wondering if the simplest way to do this is just by putting: ArrayA = ArrayA += 1 or what the simplest way to do this is.
