Don't worry, it's probably already correct - that's just the way these things are displayed in the debugger

I've had to do a bit of work printing to serial printers and instead of sending the string value to the COM port, you might want to use something along the lines of System.Text.Encoding.UTF8.GetBytes(string) for TxFrame and then append the CR (0x0D) LF (0x0A) to the byte array. It seemed to work for me.

There are a few problems with your message:
1.
"carriage return" and "line feed" are the names of two popular ASCII characters.
2.
what you want to terminate a line of text and start a new one is called "NewLine" in .NET; it is a string and its content depends on your system (Windows, Linux, ...). The default value can be found in Environment.NewLine and will be used by some WriteLine methods, such as Console.WriteLine
3.
data sent to a peripheral using a COM port, or sent to another system in some other way (e,g, portable file), or shared with another system (e.g. a database), should NOT rely on a local convention or characteristic.
4.
the SerialPort also offers a WriteLine method, which relies on its own NewLine property which in turn is initialized to a "line feed". If you explicitly set to "\r\n", you will probably get what you want.
5.
the code in your other message, with initializers D and 1, will not compile as is.
6.
code snippets should preserve their formatting, that is what PRE tags are invented for. Use them!
7.
If you hope to be successful in programming, you'll have to become a lot more meticulous.

I only read formatted code with indentation, so please use PRE tags for code snippets.
I'm not participating in frackin' Q&A, so if you want my opinion, ask away in a real forum (or on my profile page).

Why not something like:
m_ComPort.NewLine = "\r\n" ;
...
m_ComPort.WriteLine ( System.String.Format ( "{0}{1}" , par , val ) ) ;

Hi All,
I am sharing tips which is about Document merging in C#.NET.
Some times during application development we need to generate a MS Word document from a predefined format and some custom data. The predefined format is generally called as Template. This template used to carry some merge fields which can be replaced with the user data.
The user data can be taken from DB or XML data source etc.
The following procedure describe how to generate a MS Word document by merging a word template with external data using C# and MS Word reference libraries.
Step 1:Create a template word document
Hello {Recipient_name},
Wish you a very Happy New Year.
Thanks
- Here {Recipient_name} is called as a merge field and this can be replaced with the external content.
- The shortcut key to create the merge field in word document is : ctrl+F9
Hope you find this tipshttp://www.mindfiresolutions.com/Document-merging-in-CNET-734.php[^] useful and of assistance.
Thanks,
Bijayani

This isn't the right place to post this. This is a tip/trick, so it should be posted as one. By posting here, you have made it appear as though this is a question, and it will soon disappear from this page. I would suggest that you move it now.

Is there any dll file or other tool for .net framework 2.0 by which we can change look/ appearance of controls of window forms. I need it for VS 2005 and .net framework 2.0
Thankx in adv.

It would be helpful if you provide a more specific example of what you are trying to achieve. What do you mean on changing the appearance/look of controls?
|
|
|
|
|
Actually I want to change style of controls like- trianglr button, stylish appearance of any other control etc. Please suggest me any tool for VS 2005.

Without knowing which parts you want to change, I can only suggest that you look at the use of Themes if you just want to change the theme, or search for owner drawn (control of your choice) c# in google.

Hi,
I need to build an image editor that should have all the functionalities of photoshop. The images should be loaded in a repeater or a listview control showing thumbnails. I should be able to drag the thumbnail on to a canvas and be able to edit the image, add layers etc...similar to photoshop and finally print it as a PDF. So far all my efforts to do this have failed. Kindly help me.
I have started developing the application. I have sucessfully loaded a Repeater Control with images...sort of like an image gallery. Now i want to drag those images into a canvas like that of photoshop and be able to add layers and other effects. I am unable to do that. Is there a way to drag items from a Repeater control and is there a way to call Photoshop in a .NET Application??

|
|
|
Consider checking out Paint .NET, it is an open source project. Sort of a photoshop implementation in .NET.
Best regards,
Anıl Yıldız.

It's not open source any more. It's free, but the author no longer provides the source code, something to do with people passing off his work and trying to sell it as an image editing suite.

Makes sense. Thanks for the info.
Best regards,

Hey Anil...how do i call the Paint.NET in my application. I need the code for it.
|
|
|
|
|
Hey
My program has a lot of controls on the main form and when minimizing it the screen flickers for a couple of seconds. Anyone know how to stop this?
Thanks
|
|
|
|

After the call to InitializeComponent in the main form, add the following line:
SetStyle(
ControlStyles.AllPaintingInWmPaint |
ControlStyles.UserPaint |
ControlStyles.DoubleBuffer,true);

I'm having trouble creating an 2007 Excel file from scratch using Microsoft.Office.Interop.Excel with C#.
Here is a part of my own class I'm using to create a non existing excel-file or open an existing excel-file
using Microsoft.Office.Interop.Excel;
public ExcelFile(string excelFile)
{
application = new Application();
if (!File.Exists(excelFile))
{
this.workbook = application.Workbooks.Add(XlWBATemplate.xlWBATWorksheet);
this.workbook.SaveAs(excelFile, XlFileFormat.xlAddIn8, "", "", false, false, XlSaveAsAccessMode.xlNoChange, XlSaveConflictResolution.xlLocalSessionChanges, false, Type.Missing, Type.Missing, true);
this.workbook.Close(true, Type.Missing, Type.Missing);
}
this.workbook = application.Workbooks.Open(excelFile, 0, false, 5, "", "", true, Microsoft.Office.Interop.Excel.XlPlatform.xlWindows, "\t", false, false, 0, true, 1, 0);
}
Notice I check if the excel file exist on the computer before I use it.
If the excel-file don't exist I'm trying to create it, close it and open it so I can use it in my application.
But when I try to open it after creating it, the "application.workbook.open()"-method crashes in a COMException.
If I use an excel-file which already exist, the "application.workbook.open()"-method don't crash.
What do I miss? I used this page as source: http://csharp.net-informations.com/excel/csharp-create-excel.htm[^]

I do not know the answer to your problem but I would suggest that you paste the complete ComException message into the search box on one of the search engines. You will probably find lots of hits with the exact same problem and one of them may well have the solution.
After a quick glance at the link you provided, I noticed that you haven't quite implemented the complete solution. For example you have not 'Released' any of your objects after creating and closing the worksheet. Unless you do this, I suspect that the file will be considered 'in use' therefore causing the exception.
Good luck!
