Hi,
Iam developing an application/service for printers.The scenario is as follows
1. When a user selects a document and then he says the print command(no through my application...he selects normal print in file menu)then i have to catch some details like printername,no.of pages,document name..and so on...This action should be done before it get out from spooler.
2. As all of you that after printing data from spooler will be deleted..but in general for example for HP printer 3 files like lpr1234.tmp,shockwaveobject file ,.shd are generated. In this I have take take required files and keep them in my own spooler.
On my extensive search I came to know that by using WMI and WindowsAPI functions I can get to this goal...
But Iam unable to get into the right way....
If I have to use APIs then kindly tell what are the method I have to implement(if possible give me documentation link)
If through WMI....kindly guide me for the same
ALL these should be act as a service.....
thanks in Advance

HI,
I have a grid control which has three columns viz.quantity, unit price, and total Amount column.
Quantity column can have only integer value.
I want to validate quantity column in a way so that as soon as user insert value other than integer, a message box should display showing error and return the focus to the cell.
OR
System should not allow any value other than integer into the cell.
Is there any keypress/keydown/keyup event for datagrid's cell also? If yes than please provide me code or any hint...
Please help.

You could try the following:
1 - Handle the DataGridView.EditingControlShowing event
private void DataGridView_EditingControlShowing(object sender, DataGridViewEditingControlShowingEventArgs e)
{
if (e.Control.GetType() == typeof(DataGridViewTextBoxEditingControl))
(e.Control).KeyPress += DataGridViewTextBoxEditingControlTextBoxControl_KeyPress;
}
2 - Inside the keypress event, check for the keys you need and process them
private void DataGridViewTextBoxEditingControlTextBoxControl_KeyPress(object sender, KeyPressEventArgs e)
{
if (e.KeyChar == (char)Keys.Back)
{
e.Handled = false;
return;
}
if (_dataGridView.CurrentCell.ValueType != typeof (int))
return;
e.Handled = char.IsNumber(e.KeyChar);
}
Hope this helps...

Hi there we have an in-house reporting system that I have been tasked to create a report scheduler for, I am thinking of mimicking the interface used in Windows for Scheduled Tasks so will build a GUI in c# where you choose from radio buttons
Daily
Weekly
Monthly
One time only
then configure the options depending on which first option you chose, configure your report parameters and save. This info will all be saved in the Database in my own schema (yet to define) and will be run via a scheduled sql job that processes all the data and emails out the reports. The report scheduler GUI will be a client side process users will do in our organisation and the sending of reports server side.
I already have all the code for creating the reports with the defined params and emailing out reports via a sql job.
My question is what schema to use for saving the schedule/period data? I have made a start but can be quite complicated and I'm sure someone has done this before or knows how Windows Scheduled Tasks does it. Also is there a code project example of the GUI for this already somewhere? I couldn't find anything.
Something that looks kind of like http://www.recrystallize.com/merchant/crystaldesk/reportscheduler.htm
Thanks, m.

The articles like the one you are using have their own forum/blog at the bottom of the Article. That would be the place to ask questions about any code from the article you want to use.

I don't see a post from you, nor one with this question about text in the forum for that Article.
Also you seem be completely ignoring the advice you got from senior developers when you asked this same question 3 days ago[^]
You seem very confused about extremely simple things. I strongly suggest you take the advice you were given 3 days ago.

Okay, what is your problem you are having? Show some code of what you have tried, and maybe someone will help.

HI, I need to design a form to INSERT multiple rows into database. I came up with putting textboxes forming a table. That may get the job done but it doesn’t seems to be the right thing to do. I wonder if there is a control that does the opposite of the datagridview. That instead of showing you the info of the database it lets you put information and then manipulate it to send it to a database.

Hi I have just downloaded Visual C# 2008 and I am trying to get a handle on it. I have a bit of programming experience.
I want to implement this code http://www.codeproject.com/KB/cs/TransparentControls.aspx[^]but i have no idea how to implement it.
I can load the demo I just have no idea what is going on. how do you apply the source code to a new project to implement the SkinTooltip control. Can someone either let me know a good place to go and learn or even give me a bit of a walk through. Thanks

Hi I am fairly new to C# too. You can find help in the page in the C# section or just Google C# tutorial. "C# Station" was a big help at the beginning. Maybe you cannot implement the code because most examples and tutorials were written using C# 2005 I recommend you download and use that version at least while you learn the basics. 2008 is not much different but most of the code material was written in 2005 version.

Hi,
you seem to have two issues here. One is a new language, the other Windows programming.
IMO a language is best learned by studying an introductory book or tutorial on the language;
that way you get all the basic elements presented in a logical order, with examples and rationale.
You can get a good feeling for a language in a matter of say two weeks with a book and some experiments;
this of course depends on your background. Then start reading some articles on sites like this one.
Windows programming is a lot trickier; there sure are books that may help you with that too, but
I am afraid there is a much longer learning period. Tooltips are OK, not quite straightforward though.
Transparency is really tricky. I have been a Windows programmer for 20 years now, but I would
not volunteer explaining how transparency works (also due to the fact that I'm not that interested in it).
Hope this helps.

Cool you are new to C#, may I suggest you try simpler tasks first.
viciouskinid wrote: how do you apply the source code to a new project to implement the SkinTooltip control.
You can either compile it as a dll library and reference it, I did this earlier. Or, you can add a source file to your project and just add it in.

Hi all,
The application I developed takes some memory while doing its processing.
The memory only grows if the app is kept idle. But when I minimize it, the memory suddenly diminishes.
How can I free the memory without minimizing the window?
Please guide.
Thanking you!

Thanks to this forum where I got to this site.
Any further expertise would be great though.
Thanking you!

Hi,
I'm in desperate need of help. I'm very new to C# and have only limited exposure to ASP.NET. I'm developing a win form application.
Basically, the user clicks a button and imports a text file into a sorted checkedlistbox. That works so far.
The text file will hold a list of IDs that need to be retrieved from a table in my DB. I have a stored proc in the db that does the same but when I ran that via GetStoredProcCommand, I'm getting 'Array out of Bounds' exceptions.
I've tried GetStoredProcCommandWithSourceColumns, GetStoredProcCommand, ExecuteReader, and AddInParamter, all of which won't work. I know I'm making it harder than it really is since I'm also using VS2008. If stored procs won't work, I will settle for a regular select * from table where user = CheckedlistBox.CheckedItem as well. Once I have the users I need to work with, I have several stored procs that should be run depending on the what control the user clicks. I just don't why it's not working trying to run a simple proc. Thanks in advance for your help.
I've read, read, and researched every place I could before posting here as well.
Code below
//code to load/process IDs (from import to checkedlistbox) with a stored proc in a sybase table
private void ProcessListbutton1_Click(object sender, EventArgs e)
{
try
{
//open up database connection
Database _db = DatabaseFactory.CreateDatabase();
foreach (object sysuser in CheckedListBox1.CheckedItems)
{
DbCommand cmd = _db.GetStoredProcCommand("sp_ust_user_retrieve");
}
}
catch (Exception ex)
{
MessageBox.Show(ex.Message) ;
}
-----------------------------
//import text file into Checkedlistbox
private void Importbutton1_Click(object sender, EventArgs e)
{
this.checkedListBox1.Items.Clear();
//this.checkedListBox1.GetItemCheckState();
OpenFileDialog Open = new OpenFileDialog();
Open.Filter = "Text Document|*.txt|All Files|*.*";
try
{
Open.ShowDialog();
StreamReader Import = new StreamReader(Convert.ToString(Open.FileName));
while (Import.Peek() >= 0)
checkedListBox1.Items.Add(Convert.ToString(Import.ReadLine()));
}
catch (Exception ex)
{
MessageBox.Show(Convert.ToString(ex.Message));
return;
}
this.checkedListBox1.BeginUpdate();
for (int x = 0; x < 0; x++)
{
this.checkedListBox1.Items.Add(x.ToString());
}
for (int x = 0; x < this.checkedListBox1.Items.Count; x++)
{
this.checkedListBox1.SetItemChecked(x, true);
}
this.checkedListBox1.EndUpdate();
I've tried databinding directly from the checkedlistbox and it returned all rows in the table - and overwrote what I imported. I only need to return rows from that table that are checked.
I hope this was clear. If not, please be patient with me and I will post whatever is needed.
