Hi,
Can you please specify what did you mean by 'currently open project'? Do you want to know the physical path in Visual Studio .Net? or when you are running the application?

Hi gurus,
I have an automation add-in created using C# for Excel, in which I am
exposing a number of functions. Is there any way I can add help-text
the way excel does for other categories like Financial, Statistical,
etc.
The place I want my help-text to be available is in the
Insert->Function. Here, we can select a category and function. The
corresponding help text is displayed. Now, my automation add-in is
also listed in this categories. I want help text to be displayed when a
user selects my add-in and functions in it.
I tried the MacroOptions method, but it is raising an exception.
This is the code I tried (I tried both early binding and late binding):
early binding:
code:
_excelApplication.MacroOptions("Report_Alloc", "custom description", Missing.Value,
Missing.Value, Missing.Value, Missing.Value, "Report.Report", Missing.Value, Missing.Value, Missing.Value);
Exception Message: "Exception from HRESULT: 0x800A03EC."
StackTrace " at Microsoft.Office.Interop.Excel._Application.MacroOptions(Object Macro, Object Description, Object HasMenu, Object MenuText, Object HasShortcutKey, Object ShortcutKey, Object Category, Object StatusBar, Object HelpContextID, Object HelpFile)\r\n at .......
late binding:
code:
object[] parameters = new object[10];
parameters[0] = "Report_Alloc";
parameters[1] = "Some sample description...";
parameters[2] = Missing.Value;
parameters[3] = Missing.Value;
parameters[4] = Missing.Value;
parameters[5] = Missing.Value;
parameters[6] = "Report.Report";
parameters[7] = Missing.Value;
parameters[8] = Missing.Value;
parameters[9] = Missing.Value;
_excelApplication.GetType().InvokeMember("MacroOptions", BindingFlags.InvokeMethod | BindingFlags.Public | BindingFlags.Instance, null, _excelApplication, parameters, new System.Globalization.CultureInfo("en-US"));
Exception Message: "Exception has been thrown by the target of an invocation."
StackTrace " at System.RuntimeType.InvokeDispMethod(String name, BindingFlags invokeAttr, Object target, Object[] args, Boolean[] byrefModifiers, Int32 culture, String[] namedParameters)\r\n at System.RuntimeType.InvokeMember(String name, BindingFlags invokeAttr, Binder binder, Object target, Object[] args, ParameterModifier[] modifiers, CultureInfo culture, String[] namedParameters)\r\n at ......
Inner Exception Message: "MacroOptions method of Application class failed"
Any help would be appreciated.....

Does anyone of you can tell why the following code:
private void HandleKeyPress(object sender, KeyPressEventArgs e)<br />
{<br />
char c = e.KeyChar;<br />
<br />
if(c == (short)Keys.Back)<br />
{<br />
e.Handled = true;<br />
SendKeys.Send("{LEFT}");<br />
return;<br />
}<br />
}
works in common textBox but it doesn`t work in richTextBox?
In textBox line e.Handled = true; stops the backspace key action and only action after pressing bakcspace key is move the cursor to left (SendKeys.Send("{LEFT}");).
In richTextBox it`s taken double action. e.Handled = true; code doesn`t block backspace key action so:
1) first it deletes character (backspace key do it - it isn`t block)
2) second it moves the cursor to left (like SendKeys.Send("{LEFT}"); code do)
Can anyone figure out what`s wrong with it?
|
|
|
|
|
Try this
private void richTextBox1_KeyDown(object sender, KeyEventArgs e)
{
if (e.KeyCode.Equals(Keys.Back))
{
e.SuppressKeyPress = true;
SendKeys.Send("{LEFT}");
return;
}
}
private void textBox1_KeyDown(object sender, KeyEventArgs e)
{
if (e.KeyCode.Equals(Keys.Back))
{
e.SuppressKeyPress = true;
SendKeys.Send("{LEFT}");
return;
}
}
|
|
|
|
|
It`s working 
Thank you very much 
But code
e.SuppressKeyPress = true; I turned into e.Handled = true;

Hello!

Hello!
I have wrote a code in which i m trying to hide the Notification icon when i click on the context menu (which pops on that icon). BUt in this manner two events fire. One which is my event written in the code(which works according to my requirement) and other is the Windows own event, which is Taskbar Popup menu. which always seems bad. if i call any messagebox after that fired events, the windows event hide but i don't want to show message box. Please help me.

Hi,
Sorry to disappoint you, but i wanted to ask my own question in this.
Are you able to detect when the user is clicking on the window in the taskbar?
Actually, i have made a program in which i have made the FormBorderStyle as None. This prevents the system menu to appear when i click on the window in the taskbar.
So, i wanted to figure out a way in which i could detect a click on the taskbar window and display the menu manually.
Please let me know, if you happen to know about this.
Thanks in advance.

I think, i am getting your problem.
See, when you pop-up the message box, the event is still being fired and it still shows the taskbar menu too, but the message box removes the focus and hence makes the taskbar menu disappear.
Secondly, the fact that the taskbar menu is appearing shows that you are able to hide the icon successfully, but somehow another event is being generated which is being sent again.
I am not sure about how this is happening, but i guess, you can refer to this article[^] for more details.
Also, i hope, you are using the NotifyIcon control. It saves a lot of time.
I hope this helps.

I think this will solve your problem :
try {
int port = FindUnusedPort(IPAdress.Any);
}
catch (SocketException) {
// no free ports
}
...
using System;
using System.Net;
using System.Net.Sockets;
...
public int FindUnusedPort(IPAddress localAddr) {
for (int p = 1024; p <= IPEndPoint.MaxPort; p++) {
Socket s = new Socket(AddressFamily.InterNetwork,
SocketType.Stream,
ProtocolType.Tcp);
try {
s.Bind(new IPEndPoint(localAddr, p));
s.Close();
return p;
}
catch (SocketException ex) {
// EADDRINUSE?
if (ex.ErrorCode == 10048)
continue;
else
throw;
}
}
throw new SocketException(10048);
}
Cheers

I want help in opennig only one child file at a time. My application irritates me when there are too many child forms open.
I added this code (on all the menu items) to open only one, but the problem is that, I can't open another child while there is a child active. How do you control that ?
Interfaces - Is the folder Name where all forms are located
frmPerson - is the child form (requered form to open)
private void mnuManagePerson_Click(object sender, System.EventArgs e)
{
if (Interfaces.frmPerson.ActiveForm.ActiveMdiChild == null)
{
Form frmchildfrmPerson=new Interfaces.frmPerson();
frmchildfrmPerson.MdiParent = this;
frmchildfrmPerson.Show();
}
}

Make the base class of your child form to implement the singleton pattern

How do i manipulate hashtables in c# ? i could store objects into hastables but i get problem while retrieving them back.
i tried this :
<br />
Dictionary<string, string> openWith = <br />
new Dictionary<string, string>();<br />
[here i intend replace "string" with my own object type]
but it failed,
may be because it failed even when i tried to include this
using System.Collection.Generic;
it says like "are you missing any assembly reference?"
BTW, just like we have vectors in C++, what's the equivalent container in C# ?

A potentially dangerous Request.Form value was detected from the client.
I have a webpage using .net 2.0 with
an asp:button Back and
a textbox with text = "<space>"
I've done my research and everything I see says set ValidateRequest="false" in page directive which I did.
There's no problem if I click the browsers back button. But when I click my own asp button BtnBack, the error is produced. Is there something like setting the validation within my own button?
Thanks!

Hi,
When browser back button is clicked, no new request is sent to browser, I think(unless we expire the page programmatically). Most probably, you have written a Response.Redirect in your asp button click, right? So, the html code gets posted to the server and server generates the error.
You can either call History.Back(or something like that in javascript) in your button click or you can set ValidateRequest = "True"
Regards,
Jim
