Is it possible to programmatically highlight a column in a DataGridView that I have right-clicked on (to display a ContextMenu)?
The column headers have been hidden from the user.

i have a problem that i cant figure out.... i am busy writing a project, simple... objective is to get my code to disable explorer.exe after a certain period of time (or at the date i set it to), then explorer.exe should close in the task manager and the task manager should be locked, and then i wanna incorporate a authentication code of sorts to unlock the task manager and open explorer.exe again...
any help on this topic would very much be appreciated.

I think you'd better specify why you want this to happen since at the moment it looks like you are writing some sort of virus or code that will harm a computer and nobody here will help you do that

Hi,
I am Using VB.NEt 2003 and MS Access 2003 for my Project. In My Access database there are 7 tables and capacity 400kb. But when i am executeing program the database capacity is increasing significantly. My initial database capacity is 400kb. But After executing 50 times it increased to 4.5 MB. Sometimes after executing 100 times it increased up to 123MB. In my database, only 2 tables are updated while executing the program. When executing the program, 60 and 30 data records are inserted to the above 2 tables. But every inserting time, previous data record sets are deleted.
Please can anybody help me?

The answer is simple - you need to compact the database.
Whenever records are deleted from an Access database the space those records take up is not freed up.
So if you keep adding and deleting records your database will keep growing until you compact it.
The only way to retrieve free space from the database is by compacting it.

You will have to write a setup bootstrapper, or Google for ".net setup bootstrap" to use an existing one.
The problem you're going to run into is that you can only have one .MSI based installation running on a machine system-wide. An .MSI installation cannot launch a second .MSI installation and wait for it to complete. Each install must be checked for and launched by an .EXE-based installer.

Define what you mean by "access". What do you want to do with it, whatever "it" is...??

I generated a list of media files in listbox. files are located on the server. first i include the wmp on the form which perform good. but did not play all types of media. need codecs. now i want that when client click on the list box the file should be opened on the client's computer on his default media player whatever he prefered to installed. like vlc, power dvd player etc etc rather than windows media player.
sir i am working on local area network and this part of the project is depends on ftp server.
I will be grateful for your kind support

The files being on an FTP server will pose a bit of a problem. Since you can't add a COM component to your form, since you won't know which plyers are installed, you have to shell launch each file using a command line, just like double-clicking the file in Explorer. The problem is that this approach does not work with FTP files because the command line you have to use will quite possibly launch a clients FTP client instead. The commandline would have to be:
ftp:
In order for this approach to work, you'd have to download the file to the client machine first, then launch the command line for the newly downloaded file. The new commandline that would launch the default player would be something like:
C:\Windows\Temp\content.mpg
The only way the first URI would work is if you could pass the path as a parameter to the media player when you launch it, or if it is added to your form as an object out of the toolbox.
wmplayer ftp:
but, you don't know what players are installed, or what file extensions will successfully play in each player.
It would seem you have a choice to make...

 Hi all ,Presently i am working on a task i.e.,i am having a toolstrip , i added textbox,RB,Label,Checkbox,etc , when i select a control on toolstrip,a run time control has to generate and paste on panel ,But i am not able to drag & drop the control to any place on the panel and make a new selection . And the other thing is when i click a new generated textbox ,it has to show the Textbox edges like in vs toolbox and after that i have to set properties for that runtime generated textbox or radiobutton .Actually, it has to work like VS.Net 2005 Toolbox with some controls on it -- this is actual idea
Waiting for help Urgently---

I'm not sure I got the whole question right but for the drag and drop problem look at the property allowdrop.
to set the properties at runtime you'll need to create a properties form where you can do this
also look at user controls it might be easier to create a usercontrol then to use the standerd controls.
If my help was helpfull let me know, if not let me know why.

for the highlighting (box around the control) I think you'll have to write eighter a custom control with it in it or draw that box I don't think its possible with the standerd control.
for the moving part: without more detailed discription and/or code I can't tell you much except that if you want it done according to certain specifications its best to write it yourself in once again a user control
conclusion:
write a usercontrol that inherits label/textbox/radiobutton/... and add custom actions

for the properties of the controls you'll need to make a form or something where they can be set.
If you want to save them (most likly you will) you'll need to save them to a db or use serialisation (do some research on this since its not easy).
for the resising you'll need to use the mousedown event then check where the mouse is on the control, if its on the edge of the control then draw the rectangles, change the mouse to the appropriate arrows and put a boolean on true (this boolean indecates that the mousebutton is down also save the mouseposition since you'll need it to calculate how much the user is resising,in the mouseup event you put it to false) then in the mousemove event compare the current with the saved position and resise you'r control. I have some code that does this somewhere, when I have 10min of time I'll look for it.

Thanks For Replying ..
Now i have done the things for properties of runtime controls .I used PropertyGrid control which is in vs2005 to get the selected control in runtime .
1) DO u know how to set the properties one by one like in vs2005 properties toolbar ( Example the comboxbox shows all the items present in the form in windows )Presently i am concentrating on this .And have to work on resizing .
2) In the future , I have to save all these controls properties in to an XML file and i have to retrieve the same ,and align and look like before saving the file .
If u have any ideas of these things , Kindly reply me

haven't used propertygrid before so don't really know about 1)
for 2) you'll need serialisation or write it all you'r self (to xml) if I have time I'll make a small example for serialistion

 i created the controls at runtime on panel using toolstrip in vs2005 using vb.net , so if add this it is working on the panel, toolstrip that' all . i am not able to access the runtime control like label1 ,checkbox1,RB1 ,TB1 like that . if i am able to access the control like label1 it is showing the squares but not able to resize the runtime controls , --- using Pickbox from codeproject

in order for you to be able to access the control you'll need to give at a unique name (when created at runtime) also you should add a addhandler to it (with the click event) then in the code of you'r addhandler you can cast the sender object to label and access it like that
so something like this
on creation
dim l as new label
l.name = 'label1'
addhandler l.click, addressof label_click
the handler
private sub label_click(sender as object,e as system.eventargs)
if sender.gettype.equals(gettype(label) then
dim l as label = sender
l.doyourdrawingofthesquareshere
end if
end sub
hope this helps
