The ImageAttributes class allows you to specify a transparency key. Draw the bitmaps on top of each other using the DrawImage call on the Graphics class that takes one of these objects.

Hello,
In my project I have created a modal form for data entry. This form can be displayed from two different parentform. Th first has a listbox, the second a datagrid.
After inserting data in the modal form and saving the data, the modal form has to be cleared for a new entry.
I want the listbox or the datagrid updated after each data entry, without closing the modal form.
How can I acces a sub on the parentform for displaying the data ??

Dear Team Members,
I am stuck at a point and so desire to be helped out of loop.
I want to implement a screen saver application with my vb6.0 application.
It is for touch screen enabled application .....so no keyboard but only Numberpad.
If a user does not touch the screen for period of 30 seconds , the screen saver is envoked and it remains till the user touches the screen again.
How do I check the idle time ..
It goes like .........
if no_mouse_event & timeinterval=30<br />
do<br />
call routine screensaver<br />
loop untill no_mouse_event=FALSE<br />
endif
I guess, I have understood what i wanted but my inexperienced programming tact make me a sufferer.
Can any  soft hearted do the favor ![Rose | [Rose]](https://codeproject.global.ssl.fastly.net/script/Forums/Images/rose.gif) to me.
Xtrisk........

I don't know what OS this for, but in 2000 & XP there is a function called GetLastInputInfo. The function parameter is LASTINPUTINFO structure:
Private Type LASTINPUTINFO<br />
cbSize As Long ' = 8<br />
dwTime As Long<br />
End Type
As far as the time you can add a windows timer (SetTimer) or add a timer control (vb)
You can compare the LASTINPUTINFO.dwTime against GetTickCount() function to calculate the time elapsed.
Hope this helps

You need to first read the text file into an array. Then make the array your data source.

How can I add the contents of one array into another which is already got values in it. The arrays are exactly the same.
|
|
|
|
|
|

You have to redim preserve the first array and then copy the contents of the second one on the first by hand (crappy solution), but be wary that redim preserve has some performance issues.
But I think you can use the ".copy" method to achieve the same result.

First of all i´d like to say Hi to all the members of this forum, and say thanks to the webmasters of this page; it´s a great one 
My problem is the following:
I started developing VB.NET App about 5 months ago, and i am very concerned about database performance, because the software I develope at my job mainly involves using them.
I´ve been working on a project for about 2 months that uses an access database shared on a network folder (yep, that sucks i know) and i´d really like that someone tell me about a webpage or a book from where i can gain some expertise about that.
Currently, my app does one operation where it has to make several select and update commands, making the process very slow... While making that, the form of the app stutters, tried to use application.doevents, but was not very effective... should it be wise to create a thread and complete the operation in that thread?
As you see, i´m very newbie to this, and i feel a little lost... Hope that someone can lead me hand. Thanks a lot for reading, and sorry about my english

Your problem is probably that the queries take to long on access. Why can't you use SQL Server? If you're stuck with Access I suggest finding a good book on Access SQL. Try writing your queries differently. Make sure each table you are updating has an index and a useful Primary Key. How many users do you have? I wouldn't even try to use access with more then few users.
One thing that may help is to map the network drive to the computer where you are hosting the web ap.

Thanks a lot for answering, Todd. In fact, it isn´t a web app, but a desktop app... It uses linked tables to connect to other tables from other Access Databases, so... as you guessed right, performance is very degraded.
Why we are using access? Good question. The reason is that our software must connect to an Access database that our client uses and it´s not possible to convince him to change to another database engine, and that´s not the best thing, the database that our client uses has a web interface in top of it.
Leaving the database question, is it possible to launch my queries process on a new thread so the forms and the app doesn´t stutter when the user tries to move the window or click on some control? (application.doevents doesn´t do the trick).

Yes it's possible to use threads. You'll have to set the time out property on your connection to something higher then the default. Everything you need to know about threading is right here

Is it possible when populating a datagrid you can use an array of values. What I mean can you use the fill dataset i.e. .Fill(dataset, "Customers")
What I am trying to use, is use the DataGridTableStyle methods i.e. mapping etc
At the moment I am using this method ......
dt.Columns.Add(New DataColumn("Floor", GetType(String)))
This is not very good as I cannot get seperate width etc or the properties of DataGridTableStyle
Am I doing something wrong or how can the above be done.
Thanks in advance
