Look, before you start implementing something, give it sometime and RTFD. It is well documented. Before you start working on your C# application, interact with ImageMagick from the command line. Once you figured out everything you need then start coding.
If you have specific question, I am sure will find it in the documentation.
I have a datagrid and I want to populate it from the tables in MS Access. Also I want to get the combination of different columns from the 3 Tables and populate them by providing my own column names in DATA GRID.
Connect to the database and get data into a dataset. All you need is a query to get the data from all the tables into one. (I am suspecting Union or join like scenario here.)You do have options of having your own column names. A bit of search in the documentation will help you.

I am developing an application on Win mobile 5.0 emulator in C# using Visual studio 2008.
Can anyone let me know how to write an SQL statement in C# which returns the row count?
Is the parameter required to store the count value?
I will be greatefull if someone helps with the code snippet for the same.
I have tried the following code for the select statement(the select stmt does not return the row count value) and is working fine.
SqlCeDataAdapter adap = new SqlCeDataAdapter();
String connstring = @"Data Source=Program Files\signup\signupdb.sdf";
conn = new SqlCeConnection(connstring);
comm = new SqlCeCommand();
comm.Connection = conn;
comm.CommandText = "select * from signuptbl where username =@uname";
SqlCeParameter para = new SqlCeParameter();
para.ParameterName = "@uname";
para.Value = uname_in;
adap.SelectCommand = comm;
System.Data.DataTable dt = new DataTable();
psw1 = dt.Rows.ToString();
What changes should be done in the above code for writing a select stmt the return the number of rows selected?
I am developing an application that reads a DES encrypted password generated using Java in a properties file and decrypts it, using DESCryptoServiceProvider. I am provided with the key string originally generated with Java using DES.
Does anyone have an example or sample code that converts/uses a Java generated key to decrypt a Java generated password in C#? After removing the dashes, I get the "Specified key is not a valid size for this algorithm" exception.
I've tried both of these lines of code and get the same error:
Could anyone tell me how to setup orientation to landscape, and datetime , and tabname in footer when user print the excel sheet by default. i am sending my excel code.Could any one tell what i need to do i search in google but no luck I need In C#.
this works fine when u want working with a one TableAdapter. for multuple tableAdapters, u need extend each tableAdapter class for supporting Transactional operation.
In my scenario : i'm dealing with multiple tables (insert,update or delete to/from multiple tables) within a single transaction and i think above method does not correct for this operation. look at this code sample :
CustomersTableAdapter tableAdap = new CustomersTableAdapter() ;
SqlTransaction tableAdapTran = null;
SqlConnection tableAdapConn = null;
OrdersTableAdapter ordersAdapter = new OrdersTableAdapter();
SqlTransaction ordersAdapterTran = null;
SqlConnection ordersAdapterConn = null;
tableAdapConn = tableAdap.OpenConnection();
tableAdapTran = tableAdapConn.BeginTransaction();
ordersAdapterConn = ordersAdapter.OpenConnection();
ordersAdapterTran = ordersAdapterConn.BeginTransaction();
// What i must write here ?
can anybody help me about this issue ?
Note : i don't want to use TransactionScope class.
Could not load type 'RCH.BL.EMR.PatientEmergencyContacts" from assembly 'BL, Version=126.96.36.199, Culture=neutral, PublicKeyToken=null"
Please bear in mind the reason this is annoying is because every other use of the same assembly BL.dll works perfectly fine and when I document that line the whole things work like clock work.
Governorates = new RCH.BL.Asclepius.JordanGovernorates().GetAllFromDB();<br />
PatientNationality = new RCH.BL.Asclepius.Nationality().GetAllFromDB();<br />
NumberFormats = new RCH.BL.Asclepius.NumberFormat().GetAllFromDB();<br />
//Contact Information Type<br />
InformationType = new RCH.BL.Asclepius.ContactInformationType().GetAllFromDB();<br />
//rate of stay<br />
PatientRateOfStay = new RCH.BL.Accounting.RateOfStay().GetAllFromDB();<br />
//Emergency Contacts<br />
EmergencyContactsBL = new RCH.BL.EMR.PatientEmergencyContacts();//this is the one that's causing the gates of hell to open and unleash the demons<br />
It's clean code, and that way you can spot it when something doesn't match the pattern. Unless you have seen the code often, then the brain starts filling in the holes with the things that it expects to see..
Last time I'd reference related issue, I was pulling my hair. Finally decided to so system wide search for the assembly and see how many places I can find it. In my case, it turned out to be I'd multiple versions scattered in few places. This was a project I inherited.
Did you search the system where for the assembly? This is brute force and tedious but it may unearth a clue.
