Setting StreamWriter Buffer Size

Jan 26, 2012

I built a console application that reads a directory of files, builds a 'put' statement for each file and submits each statement to a webservice. Then, it reads the webservice output (for each statement), parses it for a specific string, builds a 'get'statement and submits the 'get' to the webservice (for each file).Then, the application reads the 'get' output stream and writes a file (to the local file system) for each file that was submitted, using a streamwriter.I have encountered an issue where some files are unable to be written to the local file system by the streamwriter.After much testing I have figured out that any file exceeding 4096 bytes will cause the application to hang where streamwriter should write the output to file.I have tried the syntax below to increase the size of the streamwriter buffer however, it doesn't seem to be working.I do need to mention that I am an extreme novice with VB or any other language and have, for the most part written this module from research and code samples.I should mention that this module does work for any file that is less than 4096 bytes in size.

Setting A TextBox Buffer Size?

Jan 20, 2009

How can a TextBox or RichTextBox buffer size be set? I have data that goes to a TextBox continuously, but I want to set a maximum size of buffer for the TextBox. I read in one forum someone suggesting to set the TextBox MaxLength property, but the questioner replied that he had tried this, and when the MaxLength was reached no further data input was possible, and what he wanted was the situation where new data could still come in, but the oldest data was then deleted, i.e a rolling buffer, which is precisely

Streamwriter And Strange Charactors - Opening The Streamwriter With Different Character Sets As The Third Parm?

Apr 21, 2010

I 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.

The reported size is 10. Can someone explain the difference here? My hunch is that VB6 is using a .75 step because my system is configured at 96 DPI, and .NET is not using said step, or not reporting its usage, but I'm not sure.

Change Application Screen Size Setting

Jul 27, 2010

I am working on an application using vb 2008 express. I have built test programs over the past few weeks and shared them for feed back. Today when I finished some work, I built another test application, but when I install it the start-up screen maximizes but is set between one and two desktop icons from the top of the screen.

In debug mode it looks fine. In the past it looks fine. Each time I start the program the screen is in a slightly different location. It is set to start maximized and to the best of my knowledge, I did not change any settings in the property area. I have tried loading on three computers and the results are the same. Any ideas on what I could have done to produce this strange result?

Rich Text Formatting - Setting Font Size

Jul 1, 2010

I have created an instance of a Rich Text Box:

Dim RichText As New RichTextBox()
I was able to write to it using:

I was able to save the document to a file:

RichText.SaveFile("C:TempRTDoc1.rtf")

What I cannot find is how to set the font, and font size. IntelliSense doesn't help. Everything is "read only", meaning retrieve a current value.

Programmatically Setting Custom Paper Size For Crystal Report?

Nov 5, 2008

I have created custom paper Size "XPaperSize 15 x 12" in Printers - File - Sever Properties. In VB .net 2005 I am trying to set custom Paper Size for Crystal Report. My problem is when I run report from Vb .net, Crystal report viewer showing correct preview for custom paper size but when I give print command it's print default printer paper size e.g. Letter size.

Here's the code I'm using to print:
Dim ObjCrReport as new ReportDocument
ObjCrReport.SetDataSource(ObjPrintDataSet.Tables("PrintData"))
SetReportPageSize("XPaperSize 15 x 12", 1) ' call Procedure for setting Custom Paper Size
End Sub
[Code] .....

If I used "myAppPrintOptions.PaperSize = PaperSize.PaperLegal" then print preview & Printing coming correct. Why it's printing Letter Size where Crystal preview showing custom paper size preview? & How to set Crystal Report Printer Paper Size?
