If I had created a DLL (OS or CS) I would probably NOT have you distribute my work in encrypted form.
As a matter of fact, doing so might get you into REALLY deep trouble.
Imagine your customer being sued for illegally using copyrighted CS-DLLs he has not obtained a license for. (CS = Closed Source)
Or you being sued by the FSF because you did not follow the license for an OS product (OS = Open Source).
Being honest works best.

well the dll's that i distribute with my program are all open source so that is not the problem. But it just looks better i think.

Hello,
I'm developing a client/server application in C# and Windows Forms. When the user is logged in (in my client application) I want to detect when he hasn't used my application in a certain time (say, one hour) to automatically log him out.
Does anyone have any suggestion on where to begin?
I've tought of a timer? but how do I reset it? o mousemove and click events or in any menu item/toolbar event?
Any pointers will be appreciated!

Umm..that's actually quite a wierd one and may not do what he expects.
I previously thought as you do, but recently I added a tool bar tool in a form that has it's text set to the current date and time in OnAppIdle event on the form. (when the user clicks on it, it inserts the current date and time as text in a text field or selects the current date and time if in a date/time editor etc, also as a side effect I expected it to be useful as a clock when in the full screen form).
If you try that you will notice much weirdness about it, the time display will not update on it's own until you do something in the form (opposite of what you would expect) including the fact that if the form doesn't have the focus it won't process unless you move the mouse around over the form, if you open the form but don't click on a control it won't process, in fact the only thing that is guaranteed to fire OnAppIdle is if you click into an editable control and keep focus there, then it will mysteriously start firing regularly.
Of course this is normally perfect since I use OnAppIdle for updating various things on the form in relation to user caused change of states, but in the case of the timer it might not work very well in practice.
I think what it's doing is interpreting what exactly "idle" means, it's not strictly idle when you're not doing anything on the form.

Well, from what I understood of the situation there is a timer that runs continuously - he only wants to reset a counter when the application enters an idle state - so each time the user stops doing stuff, even for a fraction of a second, the counter resets to zero. The timer fires a few times (say once per minute) and when it reaches its threshold the timer event can do what it needs to do at that point.

Right! Yeah, I see what you mean, that actually is the easiest solution now that I think about it.

I usually don't promote my own articles on the discussion boards but I think this is what you're looking for: How to check for user inactivity with and without platform invokes in C#[^]. There's also a thread titled Other methods to detect OnIdle?[^] where I describe why in my opinion OnIdle is useless in this case.
Best regards
Dennis

Yes, exactly that is what I was hoping to know. Such an excellent article, thank you very much!
I have one question (about the Application.AddMessageFilter solution>, but I'll post it in the article's forum, so it may be helpful to someone else.
Thank you very much!

hi,
I'd like to know if it's possible in C# to access an application to make it execute some actions based on some specific events. For example, i'm using the yahoo messenger as a chat, and i'd like to make it save all the received and sent messages automatically in a specific file.doc when exiting. This is already possible with it but it has to be done manually by clicking on the save button.
Thanks,

yeah, at my school, we've been having accessing private ftp's. is this a setting that can be changed in internet explorer? what's the setting called. or any other way. I can probably find the reg. key if you know what it's called. thank you.

I would guess that is more a function of the network you are on. If you mean private meaning within your school then it will just be an FTP server within the network somewhere. If you mean you have to log on to the FTP server and you want to know where the authentication information is stored then you are out of luck as only the SYSTEM user (i.e. the operating system) has access to that.
If it is not either of these situations then you will have to be more specific in your request.

yeah, how do I add text to a textBox (programmatically, not via the user) on the next line if there is already text in it?
danke schon,
Stephen

|

textBox.Text += "\r\n" + newTextToAdd;
|
|
|
|

Also if you want to insert text at the current active point in the edit control you can programatically copy text to the clipboard then paste it in to the control by calling the controls' paste method. (it's the only way to insert text into the current position or replace highlighted text as far as i know) If you just want to append it then it's a simple: control.text+="some new text";
|

|

Sorry to correct you, but TextBox has a SelectedText property, that, when set, just does what you describe: replace the text currently selected. If there's no text selected, setting SelectedText will insert this text at the cursor position.

I want my application to send a request to search engine(Yahoo.com ,Excite,Altavista,msn) and the search engine should return the URLs of the top 10 sites that match the keywords I sent to the search engine.
I have found google.com contain an API for developers but the other search engines does not provide a similar API or web service.
Thanks in advance
|
|

|

Yes, you can use the webservice API provided by Google. For others, I'm afraid you've to resort to screen scraping (directly parse the HTML output).

If I understand you correctly, you want the user to see one thing.. say a Customer Name, but you want to use a different value, say Customer ID.. This is very easy to do.. Set the DataSource of the ComboBox (ComboBox.DataSource) and then set the ComboBox.DisplayMember for what to be displayed and the ComboBox.ValueMemeber for what the value of that item should be... example:
<br />
ComboBox myCombo = new ComboBox();<br />
myCombo.SelectedValueChanged += new System.EventHandler(this.myCombo_SelectedValueChanged);<br />
<br />
DataTable myDataTable = new DataTable();<br />
<br />
myDataTable.Columns.Add("Customer Name");<br />
myDataTable.Columns.Add("Customer ID");<br />
<br />
DataRow myRow = myDataTable.NewRow();<br />
myRow["Customer Name"] = "Joe Smith";<br />
myRow["Customer ID"] = "1024";<br />
myDataTable.Rows.Add(myRow);<br />
<br />
myCombo.DataSource = myDataTable;<br />
myCombo.DisplayMember = myDataTable.Columns["Customer Name"].ToString();<br />
myCombo.ValueMember = myDataTable.Columns["Customer ID"].ToString();<br />
<br />
private void myCombo_SelectedValueChanged(object sender, System.EventArgs e) {<br />
MessageBox.Show("Display: " + myCombo.Text + " - " + "Value: " + myCombo.SelectedValue.ToString());<br />
}<br />
hope this helps!
