In my application...

I have declared a SerialPort object in parent form & i am accessing it from a child form but

Here is sample code for some more information...

//In parent form

public SerialPort comport = new SerialPort();

child_Form childForm= new child_Form();//this is the child form
child_Form .MdiParent = this;
comport.PortName = "COM1";

//In child form

if(!((ParentForm)this.MdiParent).comport.IsOpen)
((ParentForm)this.MdiParent).comport.Open(); // Getting error on this line

((ParentForm)this.MdiParent).comport.Write("send the text on serial Port");

I am getting intellisense for parent's 'comport' in child form.

Hi,

I'm not sure if this is your problem, but I think you don't have defined baud rate, parity, data bits and stop bits for your comport.

OR

Try send your comport trough parameter to your child form.

I hope it helps,

E-mail Subject Problem

Hi,

I am still having problems having an e-mail pop-up from an <a></a> tag. The subject contains an "&" and there cuts off certain text. I was told to use Server.UrlEncode which does work to a degree, but then it adds "+" to the spaces (which I don't want), like:

Enquiry from J&D+Ship+Services

It should actually be:

Enquiry from J&D Ship Services

Here is my code in the .aspx page:

<a href="mailto:<%= Globals.InfoEmail %>?Subject=Enquiry from <%= Server.UrlEncode(Globals.CompanyLongName) %>"><%= Globals.InfoEmail %></a>

I hope someone can help me.

Regards
ma se

Add replace function your code, before sending to the aspx page, that replace the "+" with "%26".

replace(varName, "+", "%26")

Logon to Windows 2003 server.

Hello friends,

I am developing an application, in which I need (the client... which is running the application)to login to a Windows 2003 server in the domain.

I write the following function...

internal bool DoLogin(string userDomain, string userName, string userPassword)
{
string domainpath = "LDAP://" + userDomain;
string username = userDomain + "\\" + userName;

DirectoryEntry entry = new DirectoryEntry(
("LDAP://" + userDomain), (userDomain + "\\" + userName), userPassword);

try
{
// Bind to the native object to force authentication to happen
Object native = entry.NativeObject;
return true;
}
catch
{
return false;
}
}

It only works with Windows 2003 server. I mean.. when I run the application on Windows 2003 server, it login to the server.

But when I run it on a WinXp machine.. (connected in a Windows 2003 server domain) it is not login to the server and gives error.

Also I wanted to login to a Remote Windows 2003 server from a WinXp machine... connected by internet.

Can anybody guide me ... how to do this?

Thanks in Advance

Hello,

I am trying to create a static method that converts ArrayList to List<t> and vice versa. I am at a loss at how to do it, anyone care to help? I posted the code I created below.

<br />
    public static List<T> ConvertArrayListToList(ArrayList arrayList, Type T)<br />
    {<br />
      List<T> result = new List<T>();<br />
<br />
      for ( int i = 0; i < arrayList.Count; i++ )<br />
      {<br />
        if (arrayList[i] is T)<br />
          result.Add((T)arrayList[i]);<br />
      }<br />
<br />
      return result;<br />
    }<br />
    <br />
    public static ArrayList ConvertListToArrayList(List<T> list)<br />
    {<br />
      ArrayList result = new ArrayList();<br />
<br />
      for ( int i = 0; i < list.Count; i++ )<br />
      {<br />
        result.Add(list[i]);<br />
      }<br />
<br />
      return result;<br />

First step, tell us why this code doesn't work. At first glance, I assume you forgot to check 'Ignore HTML tags in this message below, and it's a List<T>, otherwise, I don't see a problem, although I may be able to if you gave me a hint.

Hi,
Do you want to use some component for this or through pure .Net.

If you dont want to use components, then have a look at java.util.zip namespace. remember that on ur machine J# Redistributable package must be installed. This is part of J# libraries.

For more details, please take a look at following link
http://msdn.microsoft.com/msdnmag/issues/03/06/ZipCompression/[^]

If you want to use a component the search for Xceed Zip components on google.

Hope this helps you !

Hi,
I have a wmv file in which I wnat to add a text data as attribute. The data is >64k.
I have written following code but it gives "The parameter is incorrect." error.

try
{
// Create a WMEncoder object.
WMEncoder Encoder = new WMEncoder();

IWMMetadataEditor metadataEditor = null;
try
{
//create encoder object
Qlikkit.WMFSDKWrapper.Functions.WMCreateEditor(out metadataEditor);
}
catch(Exception ex)
{
string str = ex.Message;
int mydata = 0;

}

// open wmv file
try
{
metadataEditor.Open("d:\\3333.wmv");
}
catch(System.Runtime.InteropServices.COMException ex)
{
string mystr = ex.Message;
string mystr2 = ex.StackTrace;
int jj=0;
}

// get the IWMHeaderInfo3 interface
IWMHeaderInfo3 headerInfo = metadataEditor as IWMHeaderInfo3;

// get attribute count
ushort Outindex = 0;
headerInfo.GetAttributeCount(0,out Outindex);

IWMEncDisplayInfo displayInfo = Encoder.DisplayInfo;

readMetadataStream();
String mydaya22 = "data" ;
System.Text.StringBuilder mydata33 = new System.Text.StringBuilder(mydaya22);

Qlikkit.WMFSDKWrapper.WMT_ATTR_DATATYPE attrDataType2 = new Qlikkit.WMFSDKWrapper.WMT_ATTR_DATATYPE();//Qlikkit.WMFSDKWrapper.WMT_ATTR_DATATYPE.WMT_TYPE_STRING;
attrDataType2 = Qlikkit.WMFSDKWrapper.WMT_ATTR_DATATYPE.WMT_TYPE_STRING;

try
{
// add attribute
headerInfo.AddAttribute(0,
"Author",
out Outindex,
attrDataType2,
0,
//myDataptr,
mydata33,
(uint)metadataSIze
);
}
catch(Exception ex2)
{
// TODO: Handle exceptions.
string str = ex2.Message;
}

Also My defination of IWMHeaderInfo3.AddAttribute is

void AddAttribute(
[In] ushort wStreamNum,
[In, MarshalAs(UnmanagedType.LPWStr)] string pszName,
[Out] out ushort pwIndex,
[In] WMT_ATTR_DATATYPE Type,
[In] ushort wLangIndex,
//IntPtr pValue,
[In, MarshalAs(UnmanagedType.LPWStr)] StringBuilder data,
[In] uint dwLength);

is it correct?

Can I lose the default XML namespace ?

XmlDocument SVGPlot;<br />
SVGPlot = new XmlDocument();<br />

<br />
...<br />
<br />
XmlElement e = SVGPlot.CreateElement("rect");<br />
...<br />
SVGPlot.DocumentElement.FirstChild.AppendChild(e);<br />

My root element has the namespace URI xmlns="http://www.w3.org/2000/svg"
The problem is that every element e I add is like:

<br />
<rect x="100" y="40" width="40" height="10" style="fill:rgb(0,0,255);stroke-width:1;stroke:rgb(0,0,0)" xmlns="" />

The xmlns="" makes my svg not to work and I don't think of a way to lose it Cry | :((

Please help me Sigh | :sigh:

Inserting string at a particular position in RichTextBox

Hello,

I have been trying to insert a string at the caret position of a richtextbox using following method

<br />
int indexOfCaret = this.rtb.SelectionLength;<br />
this.rtb.Text = this.rtb.Text.Insert(indexOfCaret, "Test");<br />

But when the text in the richtextbox exceeds, say 1 page, the flickering starts...because I am replacing the text everytime.

Please suggest another way out of this.

Thank you,

Anshuman

The index of the caret is actually SelectionStart, I believe.

If you're having to replace the text, I don't see a way around the fact that it gets replaced every time you replace it.

dont run your insertion directly in textbox.take the current text in some variable and do you replacement there and after that replace whole text of textbox with new value

I am trying to find a class to get the system info (i.e. memory usage, disk space...). I have seen several references to a System.Mangament class but its not list in the .net MSDN help files and doing a "using System.Management;" creates an error. Any ideas.

If you are looking for "System.Mangament" I can understand that your search results were sparse. Perhaps if you look for "System.Management[^]" instead... Wink | ;)

I marked the reply as "Answer" because it is supposed to be helpful, eventhough the joke is on you for misspelling the namespace.

Just click on the link that I included in my post, and you will come to the documentation.
