.net Printing With Both Texts And Images?
Dec 7, 2007
I'm new to VB.net programming on printing a page to a thermal printer (Epson T88IV). I really had a hard time figuring out how to code the printing of a bitmap image and some text, while sending commands (through font control) to the printer.I tried sending the escape characters with Control font, but the Graphics.DrawString of PrintPageEventArgs do not allow it.. so I used the RawPrinterHelper class I found on Microsoft KB. It worked out but, I cannot print a bitmap image with it.Anybody knows how to do that?

I'm working with PDFs in VB.NET using a DLL I found on code project:
[URL]
My app allows you to select multiple files in a grid and print them. The files are stored in password-protected zip files, so the first step I do is extract each selected file to a memory stream that I pass to a new PDF wrapper object. Each object gets added to a queue. Then, each object in the queue is printed, page by page, as a system.drawing.image. The whole thing runs on a background worker.
Now, extracting the PDFs to the queue uses hardly any memory. But in the PrintPage event handler, when I extract the images and send them to the printer, something must be going wrong. My memory usage explodes. Each image, of course, is large because it's rendered at 300 dpi, but the memory used by each page isn't being returned to the OS and neither is it being garbage collected. In the end, if I select enough files, I run out of memory. Why?

With 8 Images my Code works fine, but with 16 Images I get an Argument Exception after printing Image 10 or Image 15 in Line e.Graphics.DrawImage(_lPrintImg, rect, srcRect, srcUnit). This is my code. I already tried to dispose any loaded Image and used Image.FromFile instead of New Bitmap(file):
Private Sub PrintPageLandScape(ByVal e As System.Drawing.Printing.PrintPageEventArgs, ByVal PrintPage As Integer)
Dim rect, srcRect As Rectangle
Dim i, iStart2, Number As Integer

I tried to get the value text at the end of the field id equal text on the webpage at each line. I only want to get the two value text at each line which something is like this: 111.11.11.11:4000. I want to input them in the messagebox but when I clicked on the button, it displayed as "fieldid=fieldid2=". I am trying to make the project to check and get it response as like this 111.11.11.11:4000 but it got it wrong. The reason why I want to get do this is because when I get the value text with the full ip address and the open port to input the strings text on the messagebox, I can start the next method by writing the code to make the project connecting to the sever with an open port.
Here it the code:
Code:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
' used to build entire input

I am using VB 2008 & Access Databases for creating WinForm Applications. Also i am using Crystal Reports for Report solution. my question is How do i created reports such a way that they can be printed in faster Ascii Format on any DotMatrix printer. The default true type fonts make printing very slower.
I tried to use "Draft 10 cpi" font which come to available me after i installed a correct driver for my Epson printer. which also helped me overcome this problem. however it wont be the scenario with all my clients i.e. they might have different printers having different Make with different drivers installed. i have tried to open such project on there PC but the printing wont come in Draft instead the fonts get expanded too much & the print wont come right.

I am creating an application for a point of sale in a bar in which I have a form (frmTransactions) where there are some radio buttons to be selected (main groupbox), each radio button is exclusive, and some combo boxes in the second groupbox to be ticked, which are instead not exclusive.In this form I created a 'Print Invoice' button which opens the form invoice (frmInvoice) and there are some labels that display the text shown on the transactions form; although I managed to do fairly easily the part regarding the customers details I am now finding some difficulties with the part regarding the transactions selected.[code]...

I have 2 textboxes where the user enters texts of same length. I need to do a char by char comparison. For this, i used Chars(i). Now, i have been trying to highlight the differences at the string index which is different. I am not able to figure a way out for that.
for example:
string1 = HELLO
string2 = WELLM
When the user hits Compare button, the code should highlight H and W, and also O and M maybe in the same respective textboxes or 2 different labels etc.

I have a panel on a form in which I have two labels and a small picturebox. The label texts and image in the picturebox are changed from time to time program matically. I would like to have where a user can click anywhere in the panel to bring up another form, but I have not been able to make it work. Since the labels are I guess "above" the panel, if the user clicks on the label itself, it does not trigger the panel onclick event.

I have an application I am creating that displays pump information based on customers in a database. I am using VB2008 .NET3.5.I have a combobox that has a selection for a unit of measure. What I want to happen is when that is changes the labels that have a unit of measure change to reflect the change. There are 15 labels total that need to be changed and all there names are the only ones in the project that start with a X if that helps at all. I would like to avoid creating a bunch of labels and changing the visible property and just change the text value of each one.

I basically have an application that generates reports in a .html file, I use a .html file for the ease of making tables and formatting text.Now I would like to introduce a way of printing the reports from my program. Because I use a .html file, the formatting would not the correct if I was to print it directly from my application (as far as I know). For this reason, I would like to print it just like my web browser would have in order to keep the tabular data intact and the text formatting.

I'm creating an application which has an scheduler to print and it checks if there is a pending job on the print queue before it prints the next file. I use a timer which checks if there is any file to be printed on my database. Example, the timer ticks and selected 10 files to be printed, it should print the 10 files 1 at a time, if there's no print queue, that's the only time the next file should print. I think another timer is required which will keeps on checking if print queue is done. How will i do this?

I'm looking for a way to mirror text (like how Stack Overflow provides a preview of the text being entered, as it's being typed). I also need to be able to modify the texts output environment (whether it be a textbox/messagebox/etc.) for background/text color (selected from a dropdown menu). Suggestions on the best way to go about this? FYI I'm using Visual Web Developer 2008 Express and it's an aspx page.

I have a parse from Wikipedia saved in a text file in the following form: The town itself is situated to the south-east of the rock, and overlooks the Palaia Monemvasia bay. A small hamlet with about 10 houses lies to the northwest.The founding of the town and fortress of Monemvassia most probably occurred in the 6th century AD. The town was founded in 583 by people seeking refuge from the [[Slavic peoples|Slavic]] and the [[Eurasian Avars|Avaric]] invasion of Greece. From the 10th century AD, the town developed into an important trade and maritime centre. The fortress withstood the [[Arab]] and [[Normans|Norman]] invasions and conquests in 1147. Cornfields that fed up to 30 men were grown inside the fortress.What I need to do is to extract specific texts from the parse given the header names. For example, if I type in a textbot Geography I need ONLY the geography text returned.

How do I search for the words with the same font size (e.g. 15) in a rich text box and put the words into a list box? For example, consider a dictionary whose word entries are of size 15 and the rests are of 12. So how do I put all word entries into a list box and then the description (of size 12) in another list box. I am using visual basic 2010. I've tried regex but couldn't find a way of specifying the font size.Consider the bold letters of size 15 and the rests of 12.[code](physics) hypothetical truly fundamental particle in mesons and baryons; there are supposed to be six flavors of quarks (and their antiquarks), which come in pairs; each has an electric charge of +2/3 or -1/3
