.net - Print Using .net On Paper With Fixed-width And Dynamic Height?
Nov 10, 2011
I'm developing a Point Of Sale (POS) app in VB.NET and .NET Framework 3.5 where multiple items can bought at a time. I need to print all items: their code, name quantity, price in a row-column manner.
SHOP NAME date
========== =====
SL CODE NAME QTY PRICE
== ===== ===== === =====
[code]....
The width of page is fixed but the height will be dynamic.The printout will be printed on rolled paper normally used in a POS system.How can this be done?
This is a long long lojngoi sudofi usdfh ksjdhfjk sdhfgkj shgh sdfhg sdfg sdfgdsfg ... I want to specify a maximum width (eg 180) for my string and get the height returned... the picture below explains in more detail:
I would like to take print on pre-printed stationery where I need to fixed up my data in very particular place. Also the paper size is 10 inch by width and 6 inch by height and it is continuous paper which need to be take print from dot matrix printer.
I want to print bill on a roll paper using vb.net. The requirements are as follows: The width of the page is 300 pixels or 3 inches. The height of the page is variable, depending on the number of the rows in the datagrid. The page header will have an image. The names of the items could be long, so they should not be chopped, rather print on the next line.
How can i set a fixed height detail section in crystal reports regardless of record count.I set the height of detail section to 10 records. If i put 8 records, the space for other 2 records should be white space. That is, total height remain the same.
I am aware that this is a visual basic dot net post. However It was extremely simple for me to write out a file in VB6 using lines such as the following snippet
[Code]...
I want basically to export an array A (I used zero based array here) with three columns and a particular value B in fixed widths, hence the @@@@@ which means 5 spaces in to a text file defined by the FreeFNum (FreeFileNumber).
I would like to use CSV and all the other formats but some scientific programs written in FORTRAN may not support them. Anyway my file output here needs to be in this fixed width format because it will be used by proprietary software that I have no access to the source code.
I have files that are one long line of text but are made up of individual segments. I have managed to parse the segments into a string array but now need to parse each segment into its individual fields, based upon a field structure defined by the first 2 characters of the segment.For example:
CA12345ABC999999XXPPPPPPPP55 CA segment (CA is first 2 characters of segment) has fields defined as: Field Name,Start,Length
I'm using vb6 to read lines of txt files, using the code posted in ream.In.Code "Reading a Text file Line by Line". My question is how can I real a line with fixed column width, for example:
The objective is to read each part of the row. In Visual Studio 2010 Beta version the code I present below that is actually working but it doesn't work in VB6.
Using Reader As New Microsoft.VisualBasic.FileIO.TextFieldParser("C:\teste.txt")Reader.TextFieldType = Microsoft.VisualBasic.FileIO.FieldType.FixedWidthReader.SetFieldWidths(8, 30, 25, 45, 57)
I found away to read a fixed position text file, but I encounter a problem, I know which field I want to go and check, how can I jump directly to the field I need. Readfields does not helps.for instance I need to check on field 3 and 7 of the row before the next row is read.[code]is this my best approach to read a fixed position text file?
I want to set header column width for grid view. I tried HeaderStyle-Width="30px". But it is depending on Item columns. The column width is setting based on item value. But I want fixed width even if it has value or empty.
I need to write some fixed-width font (i.e Courier New or Consolas) text to a .net Winforms window in the Paint event - not using a label or any other winforms control - rather using a graphics object method to render the text onto the form's client area. I am having difficulty aligning text on different lines under headings even though it is fixed width font. How can I get a precise measurement of the width of a single character in the fixed-width font? How can I get 2 lines to print out aligned horizontally in successive text out calls?
For example: Heading 1 Heading 2 Short Other text A bit longer Still aligned?
I need a separate call to render each cell of text under Heading 2. For argument's sake - let's say column 1 items are printed in black and column 2 are printed in blue - we can't use the same text out call for the entire line.
I am trying to format a string of arbitrary length into a fixed width field for display.
Let's use a width of 20 as an example, and call the string to be formatted s. I'm adding the formatted string to a StringBuilder named b.
Dim b As New System.Text.StringBuilder() Dim s as New String
If the string I want to display is shorter than 20 characters, I can do this:
b.Append(s.PadRight(20))
or
b.AppendFormat("{0,-20}", s)
So far, so good. But, if the string is longer than 20 characters, I want the string to be truncated to 20 characters as it is appended. The code above appends the entire string.
I tried this:
b.Append(s.Substring(0,20).PadRight(20))
But, this fires an exception if the string was shorter than 20 characters.
So, I ended up with:
b.Append(s.PadRight(20).Substring(0,20))
This seems to do the job. The PadRight prevents the exception by making sure thet string has 20 characters before the Substring is performed.
I was wondering if there is an alternate method that would look more elegant and avoid padding the string just so prevent the substring from causing an exception. Have I missed a feature of String.Format that can accomplish this in one step?
Edited to add solution:
I ended up with the following code:
Module Extensions <Extension()> _ Function AppendFixed(ByVal b As StringBuilder, ByVal s As String, ByVal width As Integer) As StringBuilder
[Code]....
This uses an extension method to clean up the syntax, as suggested by Joel and Merlyn, and uses the StringBulider Append overloads to avoid creating new strings that will have to be garbage collected, as suggested by supercat.
I have a form which is a mdiParent, on this form I also have a left docking form which obviously reduces the size of the avaliable mdi area. Is there a way that I can get the width and height of the mdi area that is avaliable? I am programming in VB.Net.
I am working on a report in Excel and there's potential for quite large amounts of text easily over-running a merged sell of maximum row height size. I therefore want to be able to merge the right amount of rows to make the text fit cleanly.My idea was to try and find the height of a string when limiting it's width - essentially placing a piece of text into some kind of container, making that container fit to size (with a set width limit, in this case 640 pixels), and measuring the height of that container. With the height of the said container, I could then work out the amount of standard sized excel rows I want to merge.I tried to use a label but there's no way to set only the vertical element to be autosize.
In html I just do <img src="x.jpg" width="1px" height="2px"> how about in vb.net. Is there an easy way to do this. When you are viewing the image through the picture box
i have a RichTextBox in my application and there may be many and many lines, i dont want to use any Scrollbar in RichTextBox. i want RTB to change its height and width itself according to the lines in RTB.
I have the darndest problem. One of my forms resizes itself. In the development environment the size is 605/301. When the program runs it is much larger. In the form_load event I put the me.Width & me.Height commands and it still is much larger. I looked at the "hidden" windows forms code and can't see any resizing going on. I added a msgbox with the width & height. It says 605 & 301, yet the form is much larger.
I know to get an image's size if its a file, but what if it is located in the clipboard? I really don't want to save it from the clipboard as a file only to read its size.
I want to get the width & height of the image file.. Mine code is currently getting the file size, I also want to get the width & height.How to get width & height,
I have a form which is a mdiParent, on this form I also have a left docking form which obviously reduces the size of the avaliable mdi area. Is there a way that I can get the width and height of the mdi area that is avaliable?
im wondering if theres an easy way to get the width of a control in WPF at runtime while the control is collapsed.when i use control.Width ill get the following result: -1.#INDand control.actualWidth will return 0.0 because its collapsed.
I need to get the dimensions of an image on a server without downloading it.I thought I can request some header data or any kind of data that refer to the height and width of the image but can't find anything like that.
