I am trying to create a contact us page on my website which will send the info entered to my email address using SMTP.
I got the following error:
the SMTP server requires a secure connection or the client was not authenticated. The server response was: 5.5.1 Authentication Required.
Which fields do you think this is referrring to? (server, host, port, recipient, sender, etc?)

your smtp server requires logon...it has nothing to do with the mail itself.

Since there is no link between a file on the server and the machine name that created it, this isn't possible.

the above code get all information about file(created,changed,deleted,renamed).
In server ,there are many user access the file using our username and password. And I have to also run this program in server, server have status of all user who are connected to server using username and password.
Thanks

First of all, posting the entire app was completely uneccessary.
Second, why did you even post this at all?? The FSW cannot tell you which machine created/changed/deleted a file.
Third, ignoring all the cross thread calls is a really, really bad idea.

You can't. NTFS does not track that information.
About the best you can hope for is to get the owner of the file. There is no way to map that user back to the IP address/machine name that they were using at the time.

Hi,
I wrote a program original in VB6 (I know it's old) and now in vb.net 2008.
When the program reads music files in some cases(most of the time on vista machines but sometimes on XP) the duration returns 0. Is there another way of retrieving the lenght of an mp3/wma file rather than open it into a mediaplayer control or a solution so that it 'always' returns the write time
Thanks Jan

Hi All,
I have made a project in VB2008 in which I have bind my Grid to Class as a datasource. The column names of Grid are the property names of the class. But I need to have customize column names for my properties in the Grid. One way is to add an attribute <displayname("name")> _ for example before each property. But it is so hard to name each and every property as i have thousands of properties in this project. Someone has told me that there is a way by using IListSource.. Does anyone have any idea about that??
Regards
Ovais

You could just create the columns in the grid yourself, then just setup the bindings for each column to property yourself.
|
|
|
|
|
Thanks for your reply dear, but I have only one grid which is binded by different classes at different scenarios..
For e.g.
Instead of having separate grids for Employees, Leaves, Allowances, Deductions (to show thier respective detail), i've a single grid. When i hit Employees button, it fills with Employees class, when i hit Leaves button, it fills with Leave class, and so forth..
Hope you understand my problem.

Then if you are able to, I would suggest that you have a Form for each category. Apart from this allowing you to do as previously suggested for the column binding, it will enable your users to do side-by-side comparisons between datasets.

So what's stopping you from Clearing the Columns collection and creating a new set of columns in the same grid and binding those to the new object collection?
|
|
|
|
|
Thats what i was doing so far, but the problem is that i m unable to customize column names in the grid. Acc. to your suggestion, i suppose to name the columns for each class at the time of binding with the grid..
|
|
|
|
|
Each DataGridViewColumn derivative allows you to set the columnheader text, using it's HeaderText property, seperately from the column name it's bound to.
|
|
|
|
|
I do exactly the same in my main form, 1 DGV and throw tables at it. I have a static method that formats names according to the capitilasition eg "ContactID" becomes "Contact ID" and I use this to populate the header text, it is part of a method that is used to bind all DGVs and gives me a consistent format throughout the app. It also means you need to take your conventions all the way back to the database design. As I own the DB I have no problem with this.
My problem is that if you bind to the List<class> using the public properties you lose the sort/filter capabilities unless you implement iBindingList (I think) on each of your classes which is a PITA. So Ah Ha I though, turn each class into a datatable, at which point I chucked the entire bind to class list out and just bind to the original datatable.

Hi,
I am working on a windows application where the user should be able to move,resize and drag and drop a control (a Textbox in my case).
I am pretty much ok with the moving and drag and drop except that I cant differentiate between MouseDown and Click events, because everytime I press the mouse button on the control the MouseDown event fires up and I cant really use the click event. Is there a way that i can differentiate between MouseDown and Single Click.
Second: I am trying to highlight the control when the user selects the objects so that I highlight the control or get that resizing rectangle around the control so that user can drag it to resize the object. Something we do while creating a application (we add a control on the form and then resize it) . Can any one please help me out with this.
Thanks
If you can think then I Can.

|
|
As for differentiating MouseDown from Click, you can start a timer when MouseDown is fired. If you get a MouseUp before the timer expires, then it's a Click, otherwise it's starting a drag-and-drop.
Highlighting the control can be done for example by using the OnPaint event and adding GDI+ code to draw your highlighting depending on the component status (drag-and-drop active or inactive).
