but where are this messages stored? in one textbox? so how will user decide what is the name of file and which part of textbox text is to save?
or you simply want to save all the text from textbox but choose the file?
if so, make second textbox in which user will write the filename and save file like this:
StreamWriter msgStreamWriter = new StreamWriter(textBoxFileName.Text+".txt"); //with some validation if user written ".txt" or not
msgStreamWriter.WriteLine(textBox1.Text);
msgStreamWriter.Close();
if it is not a solution answer firts question

I am using a 3rd party library and tried to call a collection object. Worked fine in VB.NET but not in c#. in c# it asks to give an argument.Checking the definition in OBJECT browser, i found following:
VB.net:
Public Overridable Function Sessions(Optional ByVal item As Object = Nothing) As Object<br />
Member of: RepServerLib.IRepServer
c#:
public abstract new System.Object Sessions ( System.Object item )<br />
Member of RepServerLib.IRepServer
what the heck? why can't I use argument as OPTIONAL in c#? it drives me crazy. why is it not overridable in c#?

Hey don't take VBs abuse of good practice out on C#.
In pure OO terms, the VB version should actually be converted into 2 methods which would correspond to the following in C#:
public abstract object Sessions ()
{
return Sessions(null);
}
public abstract object Sessions(object item)
{
}The VB version is just syntactic sugar, and it does place some restrictions on VB code. Take this example:
Public Overridable Function Sessions() As Object
Public Overridable Function Sessions(Optional ByVal item As Object = Nothing) As Object Think about what would happen if you tried to call the no-parameter Sessions method. Not good is it?

the issue is that the "Sesion" method returns a Collection list oBject. in VB.net, i can use "Count" method while count is alien for C#.
can you please tell em what should I do?
|
|
|
|
|
Cast the returned object to a collection, and you have the Count property available. The issue here though is that the Session should explicitly return a Collection if that is what is being returned. It shouldn't return an object and then rely on you to cast the object. Apart from anything else, this is going to result in unnecessary boxing/unboxing on this object.

Because C# doesn't support optional parameters.

This[^] article might help you with this. Alternatively, take a look at the SharpZipLib project.

Hey!
Does aynone know if it somehow is possible to get continous events when clicking (and not releasing) a button? Or if it is somehow possible to achieve this behavior in some other way?
The thing is that I want to use regular buttons for scrolling and if the user wants to scroll much he could just click and hold the button instead of clicking many times.
|
|
|
|
|
The only thing that springs to mind is to start a timer on the button down event, and on each interval, check to see if the mouse button is still down / still over the button, and if so, fire an event. If the mouse button is up / not over the button, stop the timer.
It's 0800hrs here, my brain doesn't get into gear until about 1000hrs, so there might be a much better way.

For a starter, I think you don't need to check state of button, but simply stop the timer on mouse up event of the button.  Other then that, your idea looks ok to me.

if you don't check button state, if user moves his mouse with mousebutton clicked the program will still behave like the button would be clicked.

I stand corrected, MouseUp OR MouseLeave.
I still think it's better to use available events then setting up timer and checking manualy. Then again, it's quite possible that I am missing something, since I've been doing exclusively web dev lately.

It's 1000 here, and I can't think of a much better way either.
Unless I take longer to get my brain into gear. In fact, I browse these forums every morning to do just that - start thinking in developer mode and not human mode anymore.
I do not believe they are right who say that the defects of famous men should be ignored. I think it is better that we should know them. Then, though we are conscious of having faults as glaring as theirs, we can believe that that is no hindrance to our achieving also something of their virtues. - W. Somerset Maugham

:(sigh:Hi Everyone,
Okay in the past two weeks I have learnt so much and I'm starting to work things out on my own. However even this one is tricky for me.
I am trying to automatically check checkedlistboxes based on data in the database.
I know I have to compare the dataset tableadapter to items in the ckedlistbox and then tick them if they match the ID. But how? I have created a join table aswell with EmpID and TechSkillsID so that people can tick multiple skills and they will be saved in there. Even though it isn't working yet. and yes the foreign keys are set up correctly. My code doesn't tick anything.
This is my code.
[code]
sql = "Select t.ProgLanguagesDatabase,e.EmployeeID,e.TechnicalSkillsID from TechnicalSkills t, employees e where t.TechnicalSkillsID = e.TechnicalSkillsID and e.EmployeeID = '" + FirstnameText.Text.ToString() + "'";
for (int i = 0; i < techSkillsCheckListBox2.Items.Count; i++)
{
for (int j = 0; j < this.dataSet1.TechnicalSkills.Count;j++)
{
if (i == j)
{
techSkillsCheckListBox2.SetItemChecked(i, true);
}
}
Thank you so much

I think your logic is wrong. All you are doing is comparing two numbers - the index of the item in the collection. Imagine techSkillsCheckListBox2.Items has 4 items and this.dataSet1.TechnicalSkills has 5 items. Your loop will look like
<br />
0 = 0 : true<br />
0 = 1 : false<br />
0 = 2 : false<br />
0 = 3 : false<br />
0 = 4 : false<br />
<br />
1 = 0 : false<br />
1 = 1 : true<br />
1 = 2 : false<br />
1 = 3 : false<br />
1 = 4 : false<br />
<br />
<br />
2 = 0 : false<br />
2 = 1 : false<br />
2 = 2 : true<br />
2 = 3 : false<br />
2 = 4 : false<br />
<br />
and so on , which is not what you want. You need to iterate through the dateset, retrieve the identifier of the skill, which should match an identifier on the check box, and then set the check box.
Step through with a debugger and you will see what's happening.

Thanks. so I've heard. Just ignore i==j.I've tried everything and I know what the debugger is showing me but I would love to know exactly how to iterate through the dataset and compare the items in teh table to the items in my checkedlistbox. If the items are matching based on the techskillsID then I have to have them ticked. I have retrieved the ID by using
sql = "Select t.ProgLanguagesDatabase,e.EmployeeID,e.TechnicalSkillsID from TechnicalSkills t, employees e where t.TechnicalSkillsID = e.TechnicalSkillsID and e.EmployeeID = '" + FirstnameText.Text.ToString() + "'";
Can you suggest how I can create the if statement. I know we are supposed to be taught the logic and we find the answer ourselves, but I think I understand the logic but can't find the answer anywhere.Its the fact that I have a checkedlistbox, and a sql database and table adapters. its hard to find the exact answer when you have so many topics involved.
Thanks. Much appreciated.

I am assuming (hoping) that you create your CheckBoxList dynamically, and read the possible options from the db. When you do, you add the checks as ListItems. Something like
<br />
while (myreader.Read())<br />
{<br />
ListItem myCheckBoxItem = new ListItem( myreader["DESCRIPTION"].ToString() , myreader["ID"].ToString() );<br />
myCheckBoxList.Items.Add( myCheckBoxItem );<br />
}<br />
To select the relevant ones, read all the skills for a user from the database
<br />
sqlstring = "select skillID from userSkills where userID = 'myuser'";<br />
<br />
DataRow[] rows = dt.Select();<br />
foreach(DataRow row in rows)<br />
{<br />
string techID = row["skillID"].ToString();<br />
myCheckBoxList.Items.FindByValue( techID ).Selected = true;<br />
}<br />
And that's it. Please excuse typos etc as I can't get to a dev box to test this.
