Hello,
i am very new to C# so please be patient.
i am printing orders in my app.
so i have a button which creates the printjob.
the paper will be written in the Printpage-Event.
now i want to have a function that gets th order-object as a parm
and print it on the paper.
the reason is, that an order must be printed on severall programm modules.
private void btnDruck_Click(object sender, EventArgs e)
{
PrintDocument Druckjob = new PrintDocument();
PrintDialog Druckermenue = new PrintDialog();
PrintPreviewDialog Druckpreview = new PrintPreviewDialog();
Druckjob.DocumentName = "Rechnung";
Druckjob.PrintPage += new PrintPageEventHandler(Druckjob_PrintPage);
Druckpreview.Document = Druckjob;
Druckermenue.Document = Druckjob;
if (Druckermenue.ShowDialog() == DialogResult.OK)
{
Druckjob.Print();
}
Druckjob.PrintPage -= new PrintPageEventHandler(Druckjob_PrintPage);
}
void Druckjob_PrintPage(object sender, PrintPageEventArgs e)
{
Graphics g = e.Graphics;
StringFormat lineFmtRight = new StringFormat();
lineFmtRight.Alignment = StringAlignment.Far;
g.PageUnit = GraphicsUnit.Millimeter;
g.Dispose();
}

Can any body tell me with an example, how loose coupling is implemented in c# in a such a way that if a class is implementing some interface and if we change something in that class then consumer class doesn't gets effected and without using interface how all the classes consumer class is changed if we didnot implemen using interface.
|

Only if you tell me, with an example, of how high cohesion is implemented in c# so that the module implementing the interface is written so it encapsulates only its own duties an does not effect any of the parameters passed to it.

Hi,
I would like to achieve the following. I want to use c# code in an if statement where if the last 2 digits are equal to "xx". How would I approach this.
I appreciate the feedback, thank you in advance.

Hi,
your question isn't very clear. If the variable is an integer, all it takes is if ((var % 100) == x) .... If the value could be negative, you might need additional code.

I only read code that is properly formatted, adding PRE tags is the easiest way to obtain that. All Toronto weekends should be extremely wet until we get it automated in regular forums, not just QA.

You could try
if(Number.ToString().EndsWith("xx"))
{
}
Although it wont be as efficient as using a mod operator
|
|
|
|
|
Would that even reliably work? I mean:
(quote from MSDN)
The return value is formatted with the general numeric format specifier ("G") and the NumberFormatInfo object for the current culture.
What if under some cultures something other than 0-9 is used, or if they put something at the end, or the middle, or whatever? Do such cultures exist?
I don't know, but using mod sure is a lot safer..

never convert to string if you don't have to; it is inefficient, creates unnecessary objects, and may be error-prone (e.g. when regional settings may influence it, or when checking for a type match).

How would I go about finding the nearest number ending in 'xx' to another number?

two weeks later, and still at it???
how would you do it manually?
in order to round a positive integer A to a new value B such that B%100=C one must:
1. subtract C from A
2. round to a multiple of 100
3. add C

Hi,
I've a fair amount of knowledge on collections in C#, but most of the collections that I know of in C# are ordered, indexed or key-enumerated collections. I'm curious to know if there are any special collections that would allows us to have more that 2 fields and the corresponding row values? Please post information regarding this, in case you are aware of.
My requirement states that I have a list having following columns - Year#, Quarter#, QuarterStartDate & QuarterEndDate, with multiple rows under this (as shown below). I need to return the Year & Qtr for any given date.
Year# Quarter# QuarterStartDate QuarterEndDate
----- -------- ---------------- --------------
2010 Qtr1 01-01-2010 31-03-2010
2010 Qtr2 01-04-2010 30-06-2010
..... .... .......... ...........
..... .... .......... ...........
At present, I'm storing this data in a datatable and performing my validations. Is there a collection type in which I can store this data and iterate thru?
Appreciate your time and effort.
Thanks
Arut

You can use a Dictionary.
One way is to declare a Dictionary<YearQuater, Foo>
YearQuater is a class that defines a year and the quater.
You can also do this:
Dictionary <int, Dictionary <string, Foo >>
in this cast the key on the outer dictionary is the year (I'm assuming int), the one on the innner is the "Quarter" which I'm assuming is a string
In both my suggestions Foo is the class that contains the row information.
The only collection I've had to hand-roll is a [Formal] "Set" ie a collection with only one instance of an element within it.Dalek Dave: There are many words that some find offensive, Homosexuality, Alcoholism, Religion, Visual Basic, Manchester United, Butter.

Hi,
IMO you should turn a row of data into an instance of a user-defined class, then use a generic List of that type.

Hi all,
How can i add a TextBox on a form every time a row in a grid is added.The Gridview refreshes every two minutes for additional row and would like to have a text box next to the Row in a grid to leave a note about the data being added. So for each entry on a grid i would like to have a text box automatically created next to the new row on a gridview.So that i can leave some comments about the data being added on the grid.
Here is the Gridview :
<asp:GridView ID="gvResult" runat="server" AllowPaging="True" CellPadding="4"
Height="16px" Width="45px" AutoGenerateColumns="False"
DataSourceID="SqlDataSource1">
<EmptyDataTemplate>
<asp:Label runat="server">
NO Message List...
</asp:Label>
</EmptyDataTemplate>
<Columns>
<asp:BoundField DataField="CR_CLI" HeaderText="CR_CLI"
SortExpression="CR_CLI" />
How Can I add a text Box that is Just Blank after each Row on a Grid
</Columns>
</asp:GridView>
<asp:SqlDataSource ID="SqlDataSource1" runat="server"
ConnectionString="<%$ ConnectionStrings:vp2ConnectionString %>"
SelectCommand="SELECT TOP (10) CR_CLI FROM Call WHERE (CR_CLI LIKE '7%') ORDER BY CR_CLI DESC">
</asp:SqlDataSource>

a,c,num1,function key or key code combination when user press alt+x to another apps by socket communication. then another
apps will press those key. i came to know that sendinput should be use to simulate keypress. so please give me a easy
sample code by which i can implement my logic

Hi,
I've implemented a very simple cache in a winforms-application using a static Colletion of objects. This collection, of course, is initialized at its first use. As the cache does not need to get updated through the whole application lifetime, that's all I need.
My question now is: How to share this static collection through multiple instances of my application? I don't need an extra cache for each instance..
Thanks in adavance.
|

Unless your cache is huge or you will be running many instances of your app, I suggest you just load the cache in each process.
If you do need to share your cache, you will have to implement some sort of inter-process communication, which will get messy.

Be excellent to each other

| I don't think you can, at least not without negating the benfits of the cache. Each instance of the app has its own AppDomain, which has its own allocated memory. (You could achieve this in c++ for example). You 'd need to get a copy of the cache from one application via some sort of RPC or similar, but this would probably be slower than just getting the data again.
