Hi,
I found some code to create DSN programmatically and thought of developing a tool to download data from SQL server to Excel. The main need of this tool is to develop an application which accepts SQL query at runtime instead of embedding the query in the code itself.
The application works fine for simple queries like 'select * from XYZ'.I am getting the output in Excel sheet for the above query. but if i give complex queries, i'm geting only the column names in the excel not the data. The complex query works fine and gives output in SQL query analyzer.
could you please help me?
thanks

Nobody would be willing to open an unknown .exe anyways. So don't even bother.

How can i load data from a server database unto a datagrid on a client applicaton
bizzo
|
|
|

To access data from a server by a client system, the method depends o how are u connecting to DB
If u are using ADO and ODBC you just have to change the server location in data source...
On the server end you have to make it sure that the DB server is listening to the IP of client...i.e. Is your DB server is configured to listen to other IP's or it is just configured for localhost
Hope this will help you a bit...

Look at http://www.connectionstrings.com[^] for the connection string you want to use ( not sure if you are using odbc, ole, ado, etc ).
You then need to have your datagrid setup on the client app and tie the datagrid to the query. I'd do a search here at CP and on google before venturing further.

I had made a application in VB 2005, with a form size.. By enabling the auto scroll property i am able to manage the situation when the target screen (monitor) is smaller then native form size.
When the target monitor is bigger and the user wants to make the application full screen, i want all the controls to be aligned and also grow in size depending the screen size...
Is there any way i can achieve that

This involves proper use of each controls Anchor and Dock properties. Also, you may have to put groups of controls in various layout panels such as the Panel control, TableLayoutPanel, FlowLayoutPanel, GroupBox, SplitContainer, ... What and how you do this depends entirely on what your control layout is and how you want it to behave.
Start by creating a new project and dropping a couple of contorls on a form, playing the the Anchor and Dock properties of those controls, then resizing the parent window to see how they behave. Then add a TableLayoutPanel and start playing around with that, dropping controls into the panel.
Noone is going to be able to tell you step-by-step how to do this. You simply have to experiment with the stuff to learn how it works, then make your own decisions on how to layout your form based on what you've learned.

Thanks for your suggestion Dave... I will the same...
I was wondering if there is any com component or something like that available they way it was there for VB 6

No there isn't. Besides, how would it read your mind as to how you wanted the controls to work?

I have two forms, and what I want is to save the data in both forms to an excel spreadsheet. I want the information in form 1 to appear first, and the information in form 2 to appear after form 1.
e.g. this is the form:
I want the excel spreadsheet to appear like this:
and I want the information on the second form, form 2 to appear on cells J, K, L, M etc... after the first form 1 information.
I have a button that says "Save to spreadsheet" on form 2 and I want to save a spreadsheet with the information in the rext boxes on form 1 and 2 like I showed. Any ideas? I am using VB 2005
In the end we're all just the same

You can use the Office Interop Library to create the excel spreadsheet.

I have a text box on my form called "txtIntrest" and I want it to display the first line in a text file called "Intrest.txt". I also want that, if you change the text in the "txtIntrest", it will ask you for a password and you have to type one in and this changes the information in the text file. If you press cancel on the password screen, it reverts back to what was in text box originally.
Any ideas?
In the end we're all just the same

Hello Dave,
You can try using the following code implementation. In this I have taken a textbox and a button.
On form load, textbox automatically fills with the first line of the file. On button click, it
will check the text box for any changes and then it will do what you require. It will ask for
password and after verifying the password, make the changes back to the file. password is coded
right now. You can use various techniques to read it from a file.
BEGIN CODE
Imports System.IO
Public Class Form1
Dim myline As String
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim sr As New StreamReader("c:\test.txt", False)
myline = sr.ReadLine
TextBox1.Text = myline
sr.Close()
End Sub
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim tempstring As String
Dim result As DialogResult
If Not TextBox1.Text.Equals(myline) Then
result = MsgBox("Do you want to save changes", MsgBoxStyle.YesNo, "Save")
If result = Windows.Forms.DialogResult.Yes Then
Dim pass As String = InputBox("Enter the Password", "Admin", "")
If pass = "Password" Then
Dim sr As New StreamReader("c:\test.txt")
Dim sw As New StreamWriter("c:\Temp.txt")
While Not sr.EndOfStream
tempstring = sr.ReadLine()
If Not tempstring.Equals(myline) Then
sw.WriteLine(tempstring)
Else
sw.WriteLine(TextBox1.Text)
End If
End While
sw.Close()
sr.Close()
File.Delete("c:\test.txt")
Rename("c:\temp.txt", "c:\test.txt")
Else
MsgBox("Wrong Password")
Exit Sub
End If
End If
End If
End Sub
End Class
END CODE
I hope this will give you some idea to resolve your issue.

hi guys
maskedtextbox1.mask = "##/##/####"
mskedtextbox2.mask = "##/##/####"
i am using maskedtextbox for getting i/p of date. i have taken mask properties short datetime. my data is stored in sql server 2005 where i have taken data type is varchar(10) in dd/mm/yyyy format (28/08/2007 & 31/08/2007).
my problem is that when i execute the sql query for the selected period in maskedtextbox it does not show correct data.
e.g.
sql_str = "insert mdate into xyz (select mdate from abc where " & _
"mdate between" & " '" &maskedtextbox1.text& "' and '"&mskedtextbox2.text&"'"
"and flag= '" & mflag & "')"
or using where condition it is not executing correct data.
can i get where i am wrong ? if is there any more suggestion for me suggest me.
Thanks
bye

As you are storing the dates as text, you can't do any calcualtions on them (including comparison). You could convert every value to a date in the query, but that's very inefficient.
Store the values as dates in the database, not text.

VB6 handles date/time differently than VB.NET and SQL Server. Who cares if it "used to work" under VB6 since you're not using it now.
You absolutely can NOT store dates in the database as strings and expect to be able to do comparisons and math on those dates, when they are not being treated as dates. Instead, they are treated no differently than if you stored "iwjf948fu04f" as your date.
Using a different control will have no effect since you are STILL storing dates as strings and not actualy datetime values in the database.

Change the data type of database columns to datetime and while storing and changing the values of that field try this statement for dates
Date.ParseExact(txtMasked.text,"Format")
format means "dd/mm/yyyy" i think it is in your case. the above statement will return a Date object which can be sent to database and then retrieved

And you're telling me this why??
Yeah, but this doesn't solve the underlying problem of storing dates in the database as strings.

hi friends,
i developed a Vb.net2003 application & i have some crystal reports tooo. & i made i using default report options.. my porblem is i have some currency fields in the report which show the data with 2 decimal places.. but i want that in 3 decimal places..
anybody have any idea..
cheers..

Left Click on currency field and choose "Format Object" option, After that you saw a "Format Editor" dialog box and go to "Number" Tab.
Select "Custom Style" from Style listbox then click on "Customize..." button, After that you saw a "Custom Style" dialog box and go to "Number" Tab.
Select an option from "Decimals:" combox box that you want to show figures after decimal in currency value.
After the selection of your requirement the Decimals Combos value look like this:
Decimals: 1.000
By default currency field shows two (2) figures after decimal.
