for beginning how to develop applications using c#,u should first of all install visual studio as your development environment.then i suggest u to watch c# tutorial videos and read articles(including this site) which can help u start building applications.visual studio express edition is free,although u can find the full version and download it through torrent files.good luck my friend. don't forget to choose best answer!

i think u should create and open the connection when your windows service starts,so during the process everywhere in your code u can use that open connection.

I have developed a windows application. I put a rectangle picture as a background picture for my form. In that picture, outside the rectangle, it is colored red. In my form I set that color as the transparency color so it would show only that rectangle or any other shape as a form. It works well in my own computer, but whenever I try to use it in another computer which also has the .Net framework installed there, the color does not hide and the transparency does not work. It shows both the rectangle and the background color. What should i do? the picture is saved as BMP. I'm using C# in a Visual studio. The application is written in .Net 2.0.

hi dudes,i have an application written by c#,visual studio 2008,my database file is an access db.i have a maskedtextbox that user enters the date,(short date as 1388/02/15-it's persian date),i parse the string to date,and i insert some data into my database,icluding the parsed date.furthermore i want to update or insert records which their date is between that date and a month later.so after parsing the entered string into date,i seperate its year,month and day, so i can add a day in farsi calender format.everything's going right until in the loop i reach the date which is '1388/02/30', i get an exception which says 'string was not recognized as a valid dattime'.where's the problem? why all the days has not any problem while that specific day has the problem? i traced the application and i'm sure the string that is being parsed while the exception raises,is 1388/02/30. more desc:in persian (farsi) calender,6 first monthes of the year has 31 days,and the 6 last monthes has 30 days.

thank u both of my friends for ur answer,both of the answered gave me a pointer,but how can i relate copying data to a progress bar?

if i were u and i had data like that one u brought as an example,i would simply make an access mdb file with one table with columns of Fname,Lname,... and insert and select from that file using jet 4.0 or Oledb 12,it's much easier,but the solution is our friend gave us about xml serializing is also very easy and comforting. u can select from an oledb database like this. oledbcommand oc=new oledbcommand (); oledbconnection ocon=new oledbconnection(connectionstring); oc.connection=ocon; oc.commandtext="select *from studenttable"; oledbdatareader dr=oc.executeReader();

dude i think ur trying to move a string(lable1.text) from form1 to form2,it's easy. for example u want have a button,when clicked u want to show second form. form2 f2=new form2(); ok,now goto ur form2.cs code view,in the first lines u c something like this: public form2() { initializecomponent(); } now change the arguments that form2 needs,in the code above,u c that second form doesn need anything for being instanced,change it like this: public form2(string labltext) { ... } now when u want to make an instance of the second form,pass the string in that way: form2 f2=new form2(label1.text) in second form u can access the string throw variable labltext. have fun :rose:

hi dudes, i want to copy a table from an access database to another table on another access database in windows application using c#,what is the best solution,i dont want my application to hang while copying the data;i've tried reading record by record by a simple oledbcommand execute way,but it would take a long time,i have a lot of records in source database,how can i do the copy by using dataset?is using dataset the best solution? how? how can i relate a progress bar to that? i've seen a class named sqlbulk which works for sql databases that copies a large amount of data between tables or databases,but my database is access.i will be thankful for those who do me a favor and give me an answer.
