I have written a VB.NET program to open a word document and generate a .TIF file by printing it using the MODI printer. Usually the documents print fine. But, sometimes it appears as though all of the letters on each line are printed on top of each other which produces little square "blobs".[code]
View 1 RepliesI am doing a little program that writes to an excel file then it prints the worksheet out using
WorkSheet.PrintOutEx()
this does print out fine but i now need to select a printer before it actually prints out. How can i do this?
Visual Studio 2005 I have an application that prints formatted text to a printer. I'm using the sample code from MSDN to impliment PrintDocument.PrintPage. My function for formatting the pages uses exactly the same code.
The problem is that the actual printout is off by one line. The footer from the first page prints at the top of the next page. Subsequent pages scroll down by one line for each page printed. If I reduce my formatted text lines by one, the opposite happens... the header from the second page prints at the bottom of the first page.
I've fussed with margin settings and fonts and I just can't seem to make it print pages correctly. I'm hoping that someone out there has seen this and can offer advice.

I want to find the remaining number of prints left on the printer. I use a Sony UP-CX1 dye sub printer. If I go to Printer Properties>Preferences it tells me the remaining prints and also the total prints on the current thermal head. How can I tap into this information with vb.net?
View 1 RepliesI have a WebBrowser control in a VB.NET WinForms app. I am able to set the default printer from code and print without prompting the user. However, there is also a print button that shows the PrintDialog. If this action is done first the page will print.Then if I try to programmatically print later (again setting the default printer to some other printer) the it will print to the last printer selected in the PrintDialog box even though I am resetting the default and see the default printer being changed in Windows.It works fine unless ShowPrintDialog has a printer chosen first. Once that occurs it seems to always use that printer no matter what I do.

I have a suite of programs that currently store PDF files as BLOBs in a SQL Server database table. The purpose of this design is to take advantage of Adobe's PDF iFilter and Microsoft's Full-Text Search functionality to allow other modules of my suite to run queries against the contents of a PDF file.This has been a huge headache, however, resulting in databases that are gigantic and unwieldy. We have also run into problems getting the Adobe PDF iFilter to play nice at times. Further, re-creating the entire full-text index on an 80 GB database can take a looooooong time (when it works at all!).So, the new idea is to use the open source XPdf library to extract a copy of the textual contents from each PDF file, and instead of storing the entire BLOB, merely store that textual data for the full-text functionality. Then, instead of storing the whole PDF file in the database, it will be stored somewhere on the server's file system.My issue relates to that last bit, storing the file on the server's file system, and the subsequent serving of that file out to remote users. Currently, with the entire BLOB residing inside of SQL, it has been very simple (though not easy) to manipulate the BLOB from the server to the client and vice versa. Sending the files across the network in chunks worked out well, too. I'm not sure how to do what I want to do now, though. I'm thinking that it's not a good solution to simply make a network share where all of the PDF files are stored and let the remote user view them by issuing a: Process.Start("{remote file share}filename.pdf")What I would LIKE to do is the following:
1. A Search is run, and the end user selects a file for viewing.
2. The SQL Server knows where the file resides on the local file system.
3. Something (on the server) issues a command to create a temp copy of the file at a safe location that is shared over the network.
4. The client's program then opens the file using a web browser.
Advantages:
1. The main body of the PDF files are protected and hidden from the prying eyes of those who shouldn't see them.
2. PDF files with Fast Web View enabled will load in a linear fashion, improving user experience.
Drawbacks:
1. I don't know what the "something" is in #3 above.
2. I don't know what happens when a file type other than ".pdf" is the target of the URL in a web browser. I know simple image formats will just open, but what if the file is ".doc/x". What about any other file type? Is it the same as issuing a "Process.Start("") to the UNC path?
Trying to insert 315K Gif files into an Oracle 10g database. Everytime I get this error "ora-01460: unimplemented or unreasonable conversion requested" whe I run the stored procedure. It appears that there is a 32K limit if I use a stored procedure. I read online that this does not apply if you are doing a direct insert, but I do not know how to create the insert string for a Byte Array. This is a thick client running on the server so not worried about SQL Injection attacks.
View 1 RepliesI have an applicaiton that I wrote that converts PDFs into TIFFS using the MODI driver and it works fine except for one part. Once I use Adobe to print out the PDF to the (MODI) driver, I get a "Save As" popup. The name of the file is correct and all I need to do is to click save. Problem is that I do not want the "Save As" to appear at all. Is there a way to prevent this window from coming up and just save it to default location? I need to take my application code and make it into a windows service, so having this popup really makes it hard.

I'm printing HTML files stored on disk to tiff files using the Office MODI driver (set as the default printer). I need to multithread this code, and therefore I need to specify the output filename for the modi driver to use, otherwise I won't know which output file is for which thread. I'm currently printing the html using a webbrowser control on the form, but this not important, I'm happy to use any method that will allow me to specify the output file.

m want to display tif images into my project. then i used a third party software (trial version CPImageViewer) it's working nicely. but problem is it's 3 months trial verison and it display message while running program....'Demo version'. so it hassle for end user. then im trying to use Microsoft Office Document Image Vierwer Library 11.0.
but problem is while i first time i set file name property its display the file but then it doesn't display any file.
note that, i m developing this project using VB6 under W2K3 platform.
my used code is given below:
modivierwer.filename="c:filename.tif"
i searched a day long for useful sample but nothing find useful.
I have a vb.net application successfully processing the text in TIF files, but it is ignoring the checkboxes. Is there anyway to use MODI to process anything within the file that is not text? Such as a mark that a person has made with a pen inside a checkbox? I think I would need to be able to evaluate where the pixels are. This is for a zero budget personal project.

1. Detect if my printer is busy, because my code tells the printer to print more pages that it can cope with, so I need to delay the command for 'Print the next page' until the printer has finished printing the previous one.
2. Shift the output to my printer so that it gets printed in it's entirety on the paper, instead of seemingly being anchored to some nebulous point on the A4 page. It starts printing at X = 29mm from the left edge, and Y is 28mm from the top, and stops at X = 22mm from the right edge and Y stops at 22mm from the bottom edge, leaving (aprox) 50mm of X and 50mm of Y unprinted.
3. Get useful information on Bounds, which I'm fairly certain is what I need to control where my printing should start and finish.
