hello everyone...
i have a problem with my program, everytime i selected all items on list box then export it in excel i always got this error: "Insufficient memory to continue the execution of the program".
But when i only selected one item on list box, it works properly..

Hummmm, tough one! I think that your computer has "Insufficient memory" to process the list of items you have selected.
How did I come to that conclusion? Who knows?

Which one RAM you are using.
I think this is a RAM Capacity Problem..

Try the following code :
Dim g As Graphics = Me.Creategraphics 'or use other control on which you are drawing ur string.
Dim str As String = "Your String"
Dim myfont As New Font("Times New Roman", 16, FontStyle.Regular)
Dim txtsize As SizeF
txtsize = g.MeasureString(str, myfont)
Dim rect As RectangleF = New RectangleF(New PointF(0, 0), txtsize)
Dim mybrush As Brush = New LinearGradientBrush(rect, Color.Blue, Color.Blue, LinearGradientMode.ForwardDiagonal)
g.DrawString(str, myfont, mybrush, New Point(20,20))
Hope,you got what you wanted!

Change the ForeColor property of the Label or TextBox that you use to display the string value.
myLabel.ForeColor = System.Drawing.Color.Blue

Hi, I want to decrease the no of roundtrips to the database for that i have implemented that on form_load i am retrieving the datarows required from the database and storing those in the dataset. And i am doing all the modification(updates,delete and inserts) in dataset and finally using dataadapter and commandbuilder objects i am updating all the modifications to the database at a one shot. This is working fine.
But I need help to synchronize the dataset to the database i.e. On form_load i filled the dataset and after that another user updated the database but my dataset doesn't have these updates, so when i update database using mydataset and dataadapter and command builder the updates done by another user earlier have been overwritten. I heared that Merge method of dataset is helpfull in this scenarios, but for me it is not working so plz help me on this by giving small example.
Thanks in advance

This requirement just dictated to you that you can't just load the data in FormLoad and hold onto it. Now you have no choice but to keep the round trips and hold onto data only as long as you need to update it.
Search Googling around for "ADO.NET Concurrency" and you'll find that this is not an easy problem to solve.
Oh...and "Merge" isn't going to help you here.

This is impossible to read because you're not using any punctuation and the sentence is switching contexts throughout, leaving the reader completely dumbfounded as to what you're refering to and when.
Try explaining this a bit better so we can figure out what problem you're talking about.

What all i can get out of it is there is some issues when u are compiling the project about ur dll reference.
What u can try is go to project properties and then to publish tab. You will have a application files button which lists all the dll and included files. You can change there Publish status of ur missing dll to Include
Good luck

I have three table A, B and C. Table A contain list of books borrow everyday. Table B contain the list of Books available in library. Table C suppose to have list of book not borrowed per day. I need a sample code to do this. I am using MS Access as my Backend database.
My Code is as follows:
"Insert into TableC (BookID,[Name], Author) (Select * From Table B where BookID) Not in (Select * from Table C where [Date] between ' " & TextBox1.Text & "' and ' " & TextBox2.Text & "'"
Thank you.

Why would you put that data in a table? You are only causing redundancy in the database.
Thayhor wrote: where BookID) Not in (
You can't have one operand (BookID) inside the parenthesis and the operator (Not in) and the other operand (Select...) outside the parenthesis.
Thayhor wrote: between ' " & TextBox1.Text & "' and ' " & TextBox2.Text & "'
You should use parameterised queries. Your query is wide open for SQL injection attacks.

I got this old application that needs to be deployed locally.
I am converting it to a network-enabled version.
I finished the SQL Server conversion part.
Now I am going to do the network-enabling part.
I mostly worked with web apps.
So, I'll really appreciate if anyone can point me to the right direction for this.
Thanks.

Noone can help you at all unless you explain what you mean by "network enabled"?? This is such a generic term that it can mean anything...
|
|
|

Sorry about the confusion.
I basically meant the application will run on the server only, and will be available on the network. Therefore others will be able to use it from their computers, while its running in the server.
Thanks.

OK, so how are the clients going to use the app if it's "running on the server"?? Obviously, the app has to expose some kind of interface, either UI-based through an existing technology, like a web browser, or through an API that another application uses, such as a Windows Forms app.
Or, did you mean that the .EXE files are going to sit on the server and the clients are going to launch them from the shared location?? In which case, you're going to need to read up on Code Access Security because code running from any remote source, including authenticated file shares, is not trusted by the .NET CLR by default and will run in a heavily restricted sandbox.

Hi Dave,
Yes..we want to use the the exe files deployed on the server, because otherwise it will have to be completely rebuild.
Could you please show me the way how to set up the code access security?
I have my assembly set up for AllowPartiallyTrustedCallers, but its not helping.
Thanks.

Thanks so much Dave.

I am writing an interface to a Panasonic KX-TDA telephone system using Winsock.
I can connect to the PBX and it accepts my connection properly using TCP, then I can send the initial connect string as follows:
Mtosend = Chr$(&H0) & Chr$(&H25) & Chr$(&H60) & Chr$(&H23) & Chr$(&H80) & Chr$(&H2) & Chr$(&H7) & Chr$(&H80) & Chr$(&HA1) & Chr$(&H7) & Chr$(&H6) & Chr$(&H5) & Chr$(&H2B) & Chr$(&HC) & Chr$(&H0) & Chr$(&H81) & Chr$(&H5A) & Chr$(&HBE) & Chr$(&H14) & Chr$(&H28) & Chr$(&H12) & Chr$(&H6) & Chr$(&H7) & Chr$(&H2B) & Chr$(&HC) & Chr$(&H0) & Chr$(&H82) & Chr$(&H1D) & Chr$(&H81) & Chr$(&H48) & Chr$(&HA0) & Chr$(&H7) & Chr$(&HA0) & Chr$(&H5) & Chr$(&H3) & Chr$(&H3) & Chr$(&H0) & Chr$(&H8) & Chr$(&H0)
Winsock1.SendData Mtosend
When I monitor the connection using WireShark it appears that the PBX accepts the string properly and sends a reply back, I get 51 bytes of data back, but if I read it as a string it simply shows as a "NULL" string. If I read it into a byte array, using the following code I only get zero's:
Private Sub Winsock1_DataArrival(ByVal bytesTotal As Long)
Dim DL As String
Dim DTS As String
Dim byteData(256) As Byte
Dim i As Integer
DL = CStr(bytesTotal)
DTS = ""
Winsock1.GetData byteData(), vbArray + vbByte, Val(Trim(DL))
For i = 0 To bytesTotal - 1
DTS = DTS & " " & Right$(("00" & Hex$(byteData(i))), 2)
Next
MsgBox "TCP Rx: " & DTS & " (bytes=" & DL & ")"
Exit Sub
But when I look at the trace in WireShark, the PBX did not send only zero's it sent a valid reply, The PBX returned string started the data with a null, but the rest was valid data. What am I doing wrong?
Please help.

Its telling you something here. I suspect you are not authenticated properly for the mail server.
