I'm using VB.NET, I wonder...

1. How can I capture a specified area of screen ? User must be able to select the area they want to capture by mouse.

2. How can I set "Compressed" or "Encrypted" attribute to a file ?

3. How can I get the Icon List in an EXE or a DLL file ?

Thank you for helping!

You would have to P/Invoke the SetSystemPowerState function in Kernel32. But! 8) You can't force the system to suspend or sleep whenever you want. The system and applications can deny your request, even if you set fForce to True.

Declare Auto Function SetSystemPowerState Lib "kernel32" ( _
   ByVal fSuspend As Boolean, ByVal fForce As Boolean) As Boolean

The docs for SetSystemPowerState are here[^].

Alternatively, you could use SetSuspendState:

Declare Auto Function SetSuspendState Lib "PowrProf" ( _
   ByVal Hibernate As Boolean, ByVal ForceCritical As Boolean, _
   ByVal DisableWakeEvent As Boolean)

The docs for SetSuspendState are here[^].

What do you mean by "merge"? Copy the files to another location? Or append one file to another? ...?

The resulting file would not be usable until you took the files apart and put them back into the directory structure. You would need a method to sort out where the file boundries are in the composite file so you can determine where one file stops and the next begins.

Servers don't merge files together. Where did you get an idea like that?

Sub7 is an hacker "tool" (Trojan horse, really) that allows someone to take over your computer, without you knowing about it.

Your talking about installing code into another .EXE. This requires in-depth knowledge of the PE executable format and how the Windows Loader works. Since this technique is used nearly exclusively by hackers and virus writters, no, I'm not telling you how to do it.

Formatting to 2 decimal places

I have some figures which i store in label and textbox controls. I have used cstr(system.math.round(figure, 2)) to get it to round to 2 decimal places. What I can't find out how to do is to make it have 2 decimal places whether it needs them or not i.e. £ 24 would become £24.00.

Does anyone know a quick way that i can so this? Confused | :confused:

Cheers, V

Hi,

Try this one:

MsgBox num.ToString("##,##.00")<br />

VB6 DAO Class Reference

Does anyone know where I might be able to find a good reference that explains all the properties, functions, and classes of the DAO Reference Library? I am trying to learn how to use the Parameter Class and would like to read up on the rest. I have search google multiple times, but can not come with anything. I can't even find a good reference book at B&N. Thanks in advance.

That's because DAO has been obsolete for years now. The replacement is ADO inside the Microsoft Data Access Components. Since I can't get to MSDN now (DNS is failing), go to http://msdn.microsoft.com/data[^] and look through the docs there.

[EDIT]
You might also find the docs for DAO in the MSDN Library Archives. Go to http://msdn.microsoft.com/archive/[^] to see if they still have the docs...

Yes, there a is a little bit difficult for a people who want to learn DAO in the .NET technology era. I would like to recommend you a book, but it might be old for you to learn and it might be difficult to find it in the bookstore. As I remember, try to find the books titled “Programming DAO” published by Microsoft Press. I forgot its author name, but I think this one is the good one. Try to learn VBA books in Access 97 also teach you about DAO technology. If you have MSDN Library January 2000, then there is also a section teaching you to learn DAO Reference. Office Developer documentation also the best place for learning DAO and ADO technology.

Thanks for the information. I will try to find those books. I have had a lot more success with DAO over ADO and it seems to run faster, therefore I have been using DAO. I found some information about using the parameter class from Microsoft last night and it helped. I would just like to find a good reference for the whole object library. Thanks guys.

I would still highly recommend you abandon the DAO approach and use ADO/ADO.NET. DAO's final version is 3.6 and will no longer be available on any future version of Windows, nor will there be any updates, other than security, to functionality.

Icons referenced in resource files

Hello

In BizTalk, when adding an object, you may have an icon associated with it (.bmp). The catch is that this image can only be loaded into the corresponding object this way:

BaseFunctoid.SetBitmap("IDB_SOME_IMAGE_RESOURCE")

How do I put a bitmap into a resource file (it seems to be in base64)

Thank you

Michel

Hi,

Does anyone know of an API in VB6 (perferably) or any other way to programmatically give a user read access to a folder. I am presently using a product called Dameware, which works fine, but it removes the inheritance on the folder to which I add the user.

Any help is appreaciated,

thanks,

There is this[^] article on MSDN that shows a method of do it with VB.NET and the Active Directory SDK. There is also this[^] article here on CodeProject.
