sorry for the junk code
Hi,
I am kinda of struck in this and I found that when I hardcode the legacyExchangeDN string its getting the entry from the Active Directory but when i Parse the string from th email address
say for example Doe, John <EX:/o=First Organization/ou=First Administrative
Group/cn=Recipients/cn=jdoe<...... i parsed the string using this
the code is
--------------
int startIndex = -1;
int endIndex = -1;
startIndex = inString.IndexOf("<EX:", recIndex) + 4;
if (startIndex > recIndex + 4)
endIndex = inString.IndexOf(">", startIndex);
if (endIndex != -1)
lemail = inString.Substring(startIndex, endIndex - startIndex);
int email = lemail.Length;
logger.LogDebug("email " + email);
-------------------
It returning NULL...I dont understand why its not working, what i am doing for Hardcoding is also just outputting the lemail and Coping the same to hard code it...
Any help would be Appreciated... I am struck for more than a week....
Thanks

Hi,
so you have 10 lines of code that go wrong ?
how about debugging it, this means:
- either you single step through it and look at intermediate results
- or you add output ("log") statements to see intermediate results.
Whatever method you choose, you should soon figure out you made a simple
mistake (that could have been avoided by applying a more defensive
programming style).
Good hunting !

Hi,
I am suppose to read XML files and extract some data from certain nodes based on its attribute. What I have done is to use XmlTextReader and loop through, using select case and hardcode (inefficient and poor practice) the nodes to be extracted. I have used XmlTextReader instead of XmlDocument initially as I would not be needing Xpath. Now, I would like to know if there are ways to select the nodes based on part of its attribute name like using wildcards. I have tried using Xpath but no success. Essentially, I want to select all the nodes with attributes beginning with a certain string eg) Wanted[…., regardless of the remaining text in the attribute name field.
Can anybody please kindly point to me how to go about doing it if possible? Any advice will be greatly appreciated.
Below are sample of my code and xml file.
reader = new XmlTextReader(link);
while (reader.Read())
{
switch (reader.NodeType)
{
case XmlNodeType.Element:
if (reader.Name == "A") //To select some nodes w/o attributes
{…. }
if (reader.MoveToFirstAttribute()) {
switch (reader.GetAttribute(0)) //To select somes nodes based on attributes.
{
case "Wanted[zxx]":
…
break;
case "Wanted[yyy]":
…
…
default:
break;
….
- <Root>
<A>XXX</A>
….
- <Elements>
<Element name="Num">XXX</Element>
<Element name="xxx">xxx</Element>
<Element name="B1">1424</Element>
<Element name="Unwanted1">xxx</Element>
<Element name="Unwanted2">xxx</Element>
<Element name="Wanted[XXX]">xxx</Element>
<Element name="Wanted[YYY]">xxx</Element>
<Element name="Wanted[ZZZ]">xxx</Element>
</Elements>
</Root>

I don't think so.

Oh no. If that's the case than I'll have to hardcode the cases. Thanks for the help. Any other view or advice will be greatly appreciated.

Hi!
Im currently playing around with making a Keylogger (nothing malicious, I promise) and ive gotten everything to work properly thus far, but one feature I think would be helpful would be recognizing what window currently has focus for each keystroke, i.e. if "hello" is typed in an internet explorer window, and then "c# programming" is typed in a firefox window, is there any way for my application to both get the kaystrokes, and the window with focus... making me able to do something like this:
Internet Explorer - The Code Project:
hello
Mozilla Firefox - The Code Project:
c# programming
Hopefully ive been clear on what I would like, any help would be much appreciated. Thanks!

Hi,
you can get a window handle and then either get the window's title, or scan the
process list (Process class) to find the process it belongs to. Some PInvoke
would be required:
[DllImport("user32")]
public static extern IntPtr GetForegroundWindow();
[DllImport("user32.dll")]
public static extern void GetWindowText(IntPtr hWnd, StringBuilder sb, int capacity);

Hello everyone,
I am using the following code to specify a window to receive mouse and keyboard messages from the video window.
IVideoWindow.put_MessageDrain(this.DvdPanel.Handle);
I was wondering if I can do the following:
1- Can I distinguish between the right and the left mouse click?
2- Can I assign seprerate events to the mouse clicks?
- I would like to have ContextMenu once the right mouse is clicked; and follow the menu available on the Video Window once the left mouse is clicked.
Thank you very much and have a great day.

What is an IVideoWindow ?
1 - in your event handler, you can. It's part of the event args
2 - no

Helo Christian,
Thank you for your help. IVideoWindow is a DirectShow Interface. It is used for rendering Video images. If I am not mistaken your answer still stays the same regarding the mouse click. As I mentioned I can detect mouse click but I am unable to seperate the Left from Right mouse click.
Thank you very much for your help and have a great day.

hi all,
let's say i have the following code:
public void GetAuthors_Click(Object sender, EventArgs E) <br />
{<br />
String selectCmd = "select * from Authors where state = @State";<br />
<br />
SqlConnection myConnection = new SqlConnection("server=(local)\\NetSDK;database=pubs;Trusted_Connection=yes");<br />
SqlDataAdapter myCommand = new SqlDataAdapter(selectCmd, myConnection);<br />
<br />
myCommand.SelectCommand.Parameters.Add(new SqlParameter("@State", SqlDbType.NVarChar, 2)); myCommand.SelectCommand.Parameters["@State"].Value = MySelect.Value;<br />
<br />
DataSet ds = new DataSet();<br />
myCommand.Fill(ds, "Authors");<br />
<br />
MyDataGrid.DataSource= ds.Tables["Authors"].DefaultView;<br />
MyDataGrid.DataBind();<br />
}
there is a text file i read with lines as follows:
DECLARE @VAR0 VARCHAR(40) --Variable0<br />
DECLARE @VAR1 INT --Variable1<br />
DECLARE @VAR2 BIT --Variable2
such that the second column gets stored in string[] strVarNames (i.e. strVarNames[1] = "@VAR1")
third column gets stored in string[] strVarTypes (i.e. strVarTypes[1] = "INT")
my question is in the following line from the above code:
myCommand.SelectCommand.Parameters.Add(new SqlParameter("@State", SqlDbType.NVarChar, 1));
how do i replace the 2nd parameter type as in the following example?
myCommand.SelectCommand.Parameters.Add(new SqlParameter(strVarNames[1], ***HOW from strVarTypes[1]?***, 1));
Thank you in advance.
I am a SysAdmin, I battle my own daemons.

First of all, please tell me you're not really putting all this code in your click event handler ?
Basically, if you have a string representation of the type, you probably need to write a switch statement that works out what type to return, or you may be able to use reflection.

I can't figure out the Mesh.Save() method. Does anyone know how to use this properly? I want to save my mesh data to a .x file so that I can use it in other programs, but I can't figure out this method.

Note: *** Never give me an answer have anything to do with Visual Studio. I don't have this program, and it'll be that way for a long, long time. ***

What API are you using? (Managed DX? XNA?)
p.s. your signature sounds like something heard from a whiny slashdot linux fanboy. It discourages me, and probably others, from replying to your posts.

hello everybody,
I'm currently writing an Poker Odds Calculator.
I want this programm to read some informations from Online Poker Rooms like Pokerstars or PartyPoker. But the big problem that I have right now is that I dont know how to collect this Informations (like what text is stored in a textbox...) and transfer it to my Application so that I can calculate with it.
I searched the Internet but I didnt find anything.
Can you give me some inspirations?
This would be very great.
|
|
|
|
|
Do PartyPoker et al have a public API you could code against?
If not, you're left to stealing info from a behind-the-scenes browser (think System.Windows.Forms.WebBrowser). Such is possible, but not recommended because of difficulty and fragility, not to mention it's probably on shaky legal grounds.
|
|
|
|
|
I dont think that there is a special API, because other Odd Calculators (like 'Texas Calculatem' or 'Holdem Genius') need the Pokerwindow on top of the screen. So I think that they do Screenshots of special Parts of the Window and analyze this pictures. I'm not an very experienced Programmer so I dont know if this is correct.
But this sounds to me very 'unclean', there has to be a better way I think...
Here on Code Project I found an interesting article about a memory scanner. Would this be an option? I think I will write a little program to have a closer look to the memory befor I try the way with the screenshots.
How can I check the pokerprograms for an API?
A few weeks ago I found an article (dont know where right know) about someone who wanted to add his own controls to an external application. And he got it. Maybe it is possible to add a 'datareader' to the pokersoftware from which I can read the data in my calculator? (I dont know if this is possible and/or legal.)
I dont know what you mean with 'behind-the-scenes browser'. Can you explain it a bit for me? Or do you have a link?
I'm german, so if you dont understand something, please ask me...

Question 1) I'm just starting out in c# and am trying to figure out how to bind treeview and listview controls to the groovy new Windows RSS Platform. I see plenty of examples binding these controls to XML or databases, but none using the new platform. (FeedsManager, IFeedFolder, etc.)
Question 2) The new platform FeedsManager stores info under the application folder for the current system user. Can anyone suggest a way to create another instance of the feeds manager for different users and override the default directories that only pertain to the user signed in?
Thanks much!!

William,
Your question was well described and clear, unfortunately not too many people here have used the new Windows RSS platform. Perhaps if you ask this question on one of the RSS platform team member blogs on blogs.msdn.com, or in some other forum dedicated to this platform, you might get more help.

I use MS ReportViewer control in local mode in C# application which calls custom code module.
To reproduce issue:
1. In C# create Code module :
public class Util {
public static bool Empty(int nValue) {
return (nValue == 0);
}
}
2. In report hidden expression call use this function with integer field parameter like
<visibility>
<hidden>=Util.Empty(Fields!myintegerfield.Value))
Observed:
Error shown below.
How to force ReportViewer to call my function ?
Should I use some attribute in method declaration ?
Microsoft.Reporting.WinForms.LocalProcessingException: An error occurred during local report processing. ---> Microsoft.ReportingServices.ReportProcessing.ReportProcessingException: The Hidden expression for the textbox ‘Textbox23’ contains an error: Overload resolution failed because no Public 'Empty' is most specific for these arguments:

I have custom report viewer control in form.
Form has the following code in keypress event:
private void BaseForm_KeyPress(object sender, KeyPressEventArgs e) {
if ((int)e.KeyChar == (int)System.Windows.Forms.Keys.Escape) {
Close();
}
}
I View report containing many pages.
I Click in scroll down button in vertical scoll bar and hold down mouse left button while clicked.
I Release mouse button.
I Notized that form scrolls down continuously even
when mouse button is released.
I Press Esc key.
Observed:
Thread exception Cannot access a disposed object.
Object name: 'VScrollBar'.
How to fix this error and continuous scrolling ?

Hi,
I guess the following is happening:
1. continued scrolling: keeping the mouse button down launches several Windows messages
that get processed one after another; if the processing takes longer than the autorepeat
interval, they accumulate, and after you release the mouse the processing will continue
for a while. Probably your processing is too slow. I suggest you add some logging
(with millisecond time resolution) to the mouse down, mouse up, and scroll events.
If this confirms my theory, you should go find what makes your scrolling that slow,
and fix it.
2. disposed: once a KeyPress event is fired, you close the form, causing it (and all
its content) to disappear; if any more events have been queued in the mean time,
they may not find their control any more (such as VScrollBar). This may be a side effect
of problem 1 !
Hope this helps.

thank you very much for excellent explanation.
I'm using report viewer from fyireporting.com
Some reports may take a lot of time to scroll. It is really not possible to speed the scolling up.
How to remove the error message which occurs after pressing esc ?
Is it possible to clear message queue or is the other solution ?
