Hoe to include a schema reference in an xml file - C# Discussion Boards

Hi,

I am working on a windows application. In this I have a multiline textbox for entering the text. For this textbox I fixed the height and width to particular values. For this text box don't want to extend the width and height i.e., by using scroll bar.

I want the text should be entered only in that particular area and no scroll bar should come for this textbox. I tried this by setting different properties of the textbox like scrollbar, max length etc but they are not working..

If you have any idea to solve this please reply me.

Thanks in advance.

Hi every one
I have a log file that continually is filling by a application.
How can I read the log file?
I tried

    StreamReader tr=new StreamReader("d:\\theLogFile.txt");
            MessageBox.Show(tr.ReadLine());

but got "The process cannot access the file because it is being used by another process." error.
help please?
thanks.

Fundamentally, something has the file open for it's exclusive use.
Most likely, whatever is writing to the log has it locked. Another possibility is that, if you have the log open in notepad / word/ other text editor it locked by this.

Hi,

if your app-under-test is logging to a file by opening a file once, and writing to it, and finally closing it upon exit, then no other app can read that file while the AUT is running.

What I often do is keep the logfile closed and add a line of text to it using

public void log(string s) {
    File.AppendAllText(logfileName, s+Environment.NewLine);
}

And for apps that run for several hours, I switch logfiles regularly, so each file remains limited in size, can be deleted when no longer useful, can be copied/emailed to another location, etc.

Uufortunately the logger application does not release the log file during running...
anyway... thank you for your answers

Hi
I have a GUI class that creates a IO object that handles IP based connections, packets and whatnot. On the GUI I have a label that is supposed to report the status of the connection (connected, failed, connecting, disconnected etc...) The label update function is written as a delegate in the GUI class to allow cross-thread calls - but I cannot work out the best way to call the delegate from the child object when an IO event occurs.

Could anyone suggest the best way to do this?

Many thanks indeed

FR :

delegate.Invoke or BeginInvoke maybe?

hi,
   My requirement is pretty simple. I need to generate an xml file using C# which will refer some 3 or 4 schema files. Ill have to generate an xml file by including all the schema files and finally validating the generated xml file with all the schema files for any errors.

The problem im facing currenlty is like this:

I have an xsd file named common.xsd and another one called hardwarecommon.xsd.

Every time when i try to write a tag which is defined in common.xsd ill have to include a prefix "c:"

That is if i want to write a tag called "UUT". But this type is defined in common.xsd then ill write it as   "C:UUT". When i try writing like this im not able to get the prefix in the xml file. I don see any error but im getting as "UUT" alone. Pls someone help

This is the code im using to generate.

xmldoc = new XmlDocument();
                  xmlnode = xmldoc.CreateNode(XmlNodeType.XmlDeclaration, "", "");
                  xmldoc.AppendChild(xmlnode);
                  //adding the root element
                  xmlelem = xmldoc.CreateElement("", "TestDescription", "");
                  xmlelem.SetAttribute("xmlns:xsi", "http://www.w3.org/2001/XMLSchema-instance");
                  xmlelem.SetAttribute("xmlns:c", "urn:IEEE-1671:2008.01:Common");
                  xmlelem.SetAttribute("xmlns:hc", "urn:IEEE-1671:2008.01:HardwareCommon");
                  xmlelem.SetAttribute("xmlns", "urn:P-IEEE-1671.1:2008.03:TestDescription");
                  xmlelem.SetAttribute("xmlns:tsf", "STDTSFLib");
                  xmlelem.SetAttribute("xmlns:std","STDBSC");
                  //xmlelem.SetAttribute("xmlns:atsf", "urn:P-IEEE-1671.1:2008.01:ATMLTSFLib");

                  xmlelem.SetAttribute("xsi:schemaLocation", "urn:P-IEEE-1671.1:2008.03:TestDescription TestDescription.xsd STDBSC STDBSC.xsd STDTSFLib STDTSFLib.xsd urn:P-IEEE-1671.1:2008.01:ATMLTSFLib ATMLTSFLib.xsd");
                  xmlelem.SetAttribute("uuid", "{F9ED240A-ABA1-447e-BBBA-1A4EF0D434B1}");

                  XmlElement Element1 = xmldoc.CreateElement("UUTDescription");
                  XmlElement Element2 = xmldoc.CreateElement("Description");
                  XmlElement Element3 = xmldoc.CreateElement("c"+":"+"Identification");

I have derived a custom control from the DataGridView to enable pasting operation from the Clipboard. I am able to do almost all the operation of pasting except the following

Scenario :
1. Added the custom DataGridView to form
2. AlloUserToAddRows = true and I have also set some other required property of custom DataGridView
3. when I turn AlloUserToAddRows = true , VS adds a one default row to grid
4. so I used the following steps to reproduce the bug
a. I run application and paste the data in each cell individually on the default added row it does not add any additional row to grid
b. I copied some rows from excel sheet and tried to paste in grid by selected first cell (as current cell)
c. Programmatically, I have to calculate the number of rows required to add in grid for pasting operation which I did , and using this.Rows.Add(n); to add n number of rows (I also tried with Insert())
d. While using Add() function everything works fine except that the first row is moved to end of the grid (only in the above mentioned scenario; for everything else it works fine)
e. While using Insert () method overloads, I am getting the exception (on same line in debug mode) InvalidOperationException with message as “no row can be inserted after the uncommitted new row.”
5. I tried many things to get work around for this bug, however I didn’t succeeded

Anybody knows the any approach where I can either get rid of this bug or exception?
suggestions are also welcome!!

Reg,
Deep

Happy Coding

Hi,
I need to convert string which has EBCDIC, packed decimal and Endian data to byteArray to save it in the database. I tried the following code.

Byte[] updateByte;
updateByte = System.Text.Encoding.Default.GetBytes(strData);
//here, strData is the string

Here what happens is it converts some characters to '?' with decimal value 63. For e.g. abc(ASCII vale) after converting to EBCDIC i get [129 130 131](these are decimal values of the converted EBCDIC data). When i convert the string to byte array in order to save it in database, it changes all three characters(129, 130 and 131) to 63. This mostly happens with small case alpbhbets.

I also tried other encoding(EBCDIC-US) but this also changes more characters.

IMP: Please note that the string that i need to convert to byte array contains EBCDIC, Packed decimal and Also Endian data.

Kindly let me know how i can achieve this.

Thanks,
Deepa

Hi,

that doesn't make much sense.

1. in .NET a sttring consists of Unicode characters, nothing else.
2. in a database, data is stored in fields, having some type, such as NVARCHAR.
3. "packed decimal" needs details
4. AFAIK "Endian data" does not exist; multi-byte data (such as int or float) can be stored in big-endian or little-endian mode, where one is "natural" on a given system and the other isn't.

I suggest you provide:
1. a better explanation of what it is you want
2. two examples with available input data, and the corresponding output data you hope to get (use either all decimal, or better yet all hexadecimal).

Smile | :)

Depak - I suggest you read the guidelines for forum posting. This looked like an interesting question right up till the last 2 sentences.

He was actually being NICE to you and you just went off being rude, AGAIN.

READ THE FORUM GUIDELINES.

No one cares how urgent it is for you. The more urgent it is, the less likely you will get ANY response.

No one is going to just hand code to you.

I am using C#.net 2005 and crystal Report XI while running report the dialoge box get promted and displyed this messege that "R6025 Pure Virtual Functiona Call Error". If I clicked on Ok Button of the Dialoge Box it shows me ::

My Event Log Error Shoews as ::

Any help Appretiated..I stuck same error from no of days but coun't found any exact cause behind this.

public interface IncDec<br />
{<br />
void Increment();<br />
void Decrement();<br />
}<br />
<br />
public class MyIncDec : IncDec<br />
{<br />
private int x;<br />
public MyIncDec(int x)<br />
{<br />
this.x = x;<br />
}<br />
public void Increment()<br />
{<br />
this.x++;<br />
}<br />
public void Decrement()<br />
{<br />
this.x--;<br />
}<br />
}

Part 1: Implement a class which can be used to measure how long each invocation of the Increment and Decrement method takes (in milliseconds) and prints out this information. The class should fit in more or less transparently with existing clients of the IncDec interface.
Part 2: Imagine you need to do something similar (timing of method calls) for many places in an application. What other ideas come to mind, e.g. could you propose other ideas for getting timing information more conveniently?

I got this question need to answer, it is simple, just something confused to me. hope anyone can help me.
btw, what "The class should fit in more or less transparently with existing clients of the IncDec interface.
" means?

you need CLR Profiler for that :

I suppose your teacher (this is homework, right?) means to give you a hint. If you create a new class that inherits MyIncDec and call the base classes methods, you can use this class instead of the orignal and have a place to put your performance timing code without disturbing MyIncDec's existing users.

Standards are great! Everybody should have one!

its not homework, I konw its simple.

thanks your answer. do you think the new class inherit from interface or that class. which one is better

Hi,

this is a stupid assignment. In order to make it a realistic problem, one would need to measure a method containing hundred or more instructions to start with, not a single increment.

The code required to transparently measure the duration of an increment will probably use a derived class, virtual methods, and a StopWatch. As such it will be much slower than the original increment itself, so the result is bound to be inaccurate (on top of being utterly irrelevant).

Hi Guys,

How can we set the web browser control for example if the user load a .doc file on it then it cannot be edited? I mean, the user is not able to change file that has been loaded in the web control (example format is '.doc','.xls' etc..).

I'm trying to counter this kinda things, but sad to say, I did not find some hint or solution on how to do that.

Thank you!

regards,
erson

So far as I know, you must set a password for "Change Document" in word during saving. Wrong password means not able to edit the document.
