All you have to do is read a little documentation[^]. Pay particular attention to the links at the bottom of that page, under "Tasks".

You'll have to use a 3rd party library to open the file for you. All you have to do is Google for "PDF library .NET".

Hi,
I would like too know, from where i will be able to download the Interop.MSXML2.dll. i have to refer that in my project. i have tried the following link, http://download.microsoft.com/download/7/a/7/7a72ca2e-39cc-4600-ab36-bf3fea876a65/msxml3.msi[^]
but after installing that msi i didn't find the required dll in my machine.
pls guide me,
Thanks in advance

There is no place to download it from. Why are you even bothering with Interop'ing an old (very old and buggy) version of MSXML when all of this is already covered by the System.Xml namespace classes in the .NET Framework, which uses MSXML6?

Hi everyone,
I am new to VS 2005, i used to program with VB6. I have a problem with crystal reports in VS 2005, the crystal report viewer can not load any report that i try to connect to. When i create a report under the IDE and try to preview it, it does not show any data but shows days of the week, colours, and report types in the columns that it is supposed to show data. Please assist me with this. My email address is honest.siulapwa@gmail.com
I will greatly appreciate your help in this matter.
Thanks

i have an array of size 600 .It's type is string
dim str(599) as string
Each item has some value.
Now my question is instead of looping for 599 times to seek the substring.
Is there any function that directly find out the particular substring , without using looping.
|
|
|
|
|
No 
|
|
|
|

Hi,
You can join that array to string variable and search the particular substring from string variable with substring function

No, there isn't.
Your only other option is to create one MASSIVE string out of all the strings in your array and use the substring method on that. The problem with this method is that it will use twice as much memory as just searching through the array because not your storing each string in the array a second time in the massive string that you built to avoid using the loop.
|

You could use something other than an array.
Depending on what you are trying to accomplish you may want to use an ArrayList. It has a Contains Boolean function that will let you know if an item is in the array.
You might also look at the HashTable. It stores items in a Key - Value pair. Great for doing direct retrievals when you know the key.

i was reading the following key
HKEY_LOCAL_MACHINE\SAM\SAM
i got the permission error.That i don't have the permission to view this one.
When i right clicked the HKEY_LOCAL_MACHINE\SAM\SAM key , there I found that the user don't have the rights to view this key.
The solution that i think is... to put the code(for reading the subkeys )under try-catch block.
Is there any thing like to change the permissions programatically.

Of course it failed. SAM is the Security Accounts Manager. Only the System has permissions read/write anything in that key.

Exactly what you have to do.

You cannot give yourself permissions higher that what you already have.

It's the same in 2005, if you don't see the option, right click and select the standard menu, it's in there./

If it doesn show in the "Standard" toolbar, you can go to the Tools menu, then Options to get to VS's config options. Find "Projects and Solutions" in the tree on left and click on it. In the right side, look for "Show advanced build configurations" and enable its checkbox.

The key press event is it, it will fire when the control has focus.
There are also key up and key down events, they may be more useful, from the sound of it.

Hi,
You should add some code in Keypress Event of Form
to trap key pressed
