i want to assign a custom source which is a table column of a dataset to a combo box. i know how to do it programmatically but i need to do it from the autocomplete source property of the combo box. also if i want to assign the custom source to a list box, what should i do
i created an App that will send eails using outlook.the matter of the can be typed inside a textbox and on the buttin click event it sends the mail.Its working fine no issues
But my problem here i want to replace the textbox with a Datgrid.
I will be inserting the details directly in to the datagrid and on the button click event this datagrid should be sent.
Attached along os teh code for the app .This code will send mails form the text box.
I want it to send froma datagrid.
Can anybody tell me how we can do it?
public partial class Form1 : Form
hello... i think u have to combine the data of the datagrid into a string object and then send that.... how much detail are u planning of sending.. if u have one row one column then try somethin like
or if u have one row multiple columns, try
foreach(DataGridViewCells cell in urDataGridView.Rows.Cells)
or if u have multiple rows and multiple columns try
foreach(DataGridViewRows row in urDataGridView.Rows)
foreach(DataGridViewCells cells in row.Cells)
I havent tried it, but i bet id would work... u can use string.Format for formatting the string...
the minimum value should be 0 and the maximum value should be the length of array ( minus 1). Next generate the random number b/w the range and then use myarray[randomNo], to get a randomnly selected value from the array.
Hello....i've been working in ado.net for a few months now... and am quite confused how to use the dataset object. though i know it depends on what type of project a person is upto but still i wanted to know which one is the better approach to usin the datasets...
Approach 1: fill the dataset with all tables at project load and use the dataset for all searches and things. though as sqlserver is locally placed, i update the sqlserver tables as soon as i update the data set...
Approach 2: fill dataset with only the rows that are required... ie if u need some rows according to a criteria, write a select statement, discard ur present dataset and refil it with this statement...
Please provide full information,based on performance issues of a system...
as far as i think , i believe approach1 will be better but it becomes hard to handle when u have more tables, like 60 tables... so wat should be done in this case, "A dataset for every 10 tables"? or wat...
This depends on the type of application you want to write. It's a good practice to minimize the queries to a database when you write a web application. But still, my opinion is that it's not a good practice to read all the data from the database into a dataset. What happens when you have around 50-60 tables and each table has 50.000 or more rows. In this case you do a huge waste of memory. I think it's better practice to save into a dataset all the data needed at a certain time. This is my opinion.
lolz... cool answer... or should i say, read my whole question first and then try answering...
i have already said of making small datasets (at the end of my question)... max of 10 tables... which means max of 10 tables when data is less and it can go upto as small dataset as of one table... Also those tables should be related to each other...
now i can go on making datasets only for one row in a table and i have seen ppl doin it...and when i code, i use a single dataset for related data that is required... now i can't go on making dataset for 10 rows or 20 rows coz that won't help the cause of disconnected environment even a lil bit.
Anyways from ur answer, i feel i have a better sense than u atleast...and please don't consider answering again...
"i would think 10 times, before giving others answers that would give the impression that i am very smart..."...LOLZ

I have written one webservice. where i have to put this webservice to use by internet users? what to do for this?
Is there a way to look all exsisting webservices? if so where can i found?
Is all webservices are under one website(i.e by showing what for this webservices and their description)?
How we can found webservices?
