First timer with VB and .Net
In the following code I get the displayed error when I execute the objOS.Get. I'm executing on an XP Pro SP3 and have all updates installed. I would assume
I'm missing something but WHAT? Any help is appreciated.
Dim objMgmt As ManagementObject
Dim objOS As New ManagementObjectSearcher("SELECT * FROM Win32_OperatingSystem")
For Each objMgmt In objOS.Get
A first chance exception of type 'System.Runtime.InteropServices.COMException' occurred in System.Management.dll
An unhandled exception of type 'System.Runtime.InteropServices.COMException' occurred in System.Management.dll
Additional information: The dependency service does not exist or has been marked for deletion. (Exception from HRESULT: 0x80070433)
TIA

I want to work with Memory Mapped Files. That's why I just installed the .Net framework 4.0 beta 2.
But now I can't find the System.IO.MemoryMappedFiles dll.
|
|
|
|
|
That's because there is no such .DLL.
If you read the documentation on the System.IO.MemoryMappedFiles namespace, you'll see that there is no need to import a .DLL because that namespace is exposed by the System.Core assembly, which every .NET app already uses.

After working in Visual Studio 2008 with SP1 on my application, everything works sweet with visifire charts.
I then create an install for my application and deploy it to a seperate machine. Charts do not work, and we get system.exception with Eventype:clr20r3
Can visifire be run without VS 2008? I don't expect to install VS 2008 SP1 on every install instance of my app with visifire.
I'm using WPF, and am creating the chart dynamically through code. I'm using the latest stable/non-beta version of visifire, v2.1

Dude. HYou've already been told that you should be waiting on an answer from VISIFIRE.
The chances of someone here using that package are very very low. If you have specific questions about a vendor's product, the best place to ask is the vendor or a vendors support forms.
You've got about the same chance of getting an answer on that package here as you do just going outside and asking the first person who walks by.

Have you tried the VISIFIRE forums. I just did a quick search on there and found a post immediately saying .Net 3.5 SP1 is required on the deployment machine.

Can anyone tell me with code in vb.net how to get email notification when client has opened the email sent to him and which client and on which link and how many time he had clicked in the email sent to him

I have a board of hexagons I've created on the screen and an image (icon) that I want to fill a hexagon with when it is clicked. I have the code to figure out which hex was clicked on but I can't figure out how to get the image into the hex. My attempt:
Image hexImage = new Bitmap(@"IconH.ico");
TextureBrush hexBrush = new TextureBrush(hexImage);
texture.WrapMode = System.Drawing.Drawing2D.WrapMode.Clamp;
bitmapGraphics.FillPolygon(hexBrush, board.Hexes[i, j].Points);
But this just puts the image in the upper right of the board and clips it so the image doesn't show unless I happen to click on the upper right hex. If I set WrapMode to allow tiling I get pieces of the image in the hex I click on but it doesn't line up. I'd like to be able to pass x and y coordinates to FillPolygon to tell it center the image on the polygon but none of the overloaded methods allow it. I'd also like to be able to resize the image to fit the hex since I want to allow the user to change the size of the hexes, but one problem at a time.

Sorry to respond to my own post but even though I've been struggling with this for a couple days it just occurred to me (less than an hour after posting) that the answer might lie in TextureBrush instead of FillPolygon. It looks like the bounded rectangle that you can specify in the TextureBrush constructor might solve my problem, and the TranslateTransform method looks interesting too. I'll play around with it for a while and let you know if that solves it. If I'm on the wrong track, please feel free to respond at any time.

I'm not really sure if this is even possible. Mapping the printer is no problem but my first thought is that it would not be possible from a webpage, security restrictions and all. As far as I can see it would require an ActiveX, or similar, control.
"By using the printing portal site and indicating their location (by drill down or similar) users would be presented with a list of nearby printers for their use. Clicking a printer should create a permanent mapping to the queue for their workstation. A set as default option would also be required."

Sounds like a LAN, not a webpage on the internet. Which of those two are you targeting?

It was a request from a client. Not sure really what they are thinking at this point

Printing over a network is easy. Printing over the internet usually isn't. That doesn't mean that it's impossible, off course;
Microsoft Technet on Internet Printing[^]. You might want to check with your client, I'm guessing that he/she wants to be able to print from every internet-enabled apparatus.

From what I was able to gather from them, they don't want internet printing, they want to assign a printer on the local machine from a webpage, specifically from a webpart in a SharePoint portal site.

Hi,
am using a dll in my web project ("Owc11.dll")
Before upgrading our production server (32 bit) it was working fine. So, recently
our production server has been upgraded to 64 bit. So, while running the
application one error throwing like this:
"retrieving the COM class factory for component with CLSID {0002E55D-0000-0000-C000-000000000046} failed due to the following error: 80040154"
Anybody could you please help me asap.
These much ways i have tried,
1. dll registered in GAC also available in regedit.
2. Enabled 32 bit appln (WOW64) on 64 bit application pool by using .net command prompt. But i have 64 applns in the server. So left this method. (IIS won't support 32/64 bit applns at the same time).
3. Created Wrapper DLL and used by pre-binding method (act like interface b/w 32 bit DLL and 64 bit appln)
4. Handlers also used.
thanks in advance .
Thanks & Regards,

This normally means that it can't find the COM class factory. In other words, it can't find the appropriate DLLs. Open up regedit, and have a look for that CLSID in HKCR\CLSID.

I assume a typo there in that surely you have upgraded to 64bit as having a 16 bit server still running is quite impressive, more than 17 years by my reckoning, that being when Windows NT 3.1 brought 32-bit into the world.
Two problems spring to mind, the first is that you will have a 32-bit interop assembly, not a 64-bit one. This is fine in a GUI based solution as you can compile for 32-bit and run in 32-bit mode, however on a server it is a little more tricky. You would have to pre-compile your web app for 32-bit, and even then you may have problems. When installing office it auto-detects your operating system and installs 64 or 32-bit as appropriate so even if you persuade your web app to run in 32-bit the underlying com object will be 64-bit. Microsoft have not released a 64-bit interop assembly package for office.
Final problem is that office automation will not work running under a service such as IIS on a 64-bit server, and that usage is not supported by Microsoft. Part of the issue is the manner in which 64-bit servers initialise the office process. They fire it up in the Administrator profile rather than the profile you are running under meaning that you will not be able to access any documents you try to open.
Not so much help, as bad news I'm afraid. We are facing the same issue, but thankfully are just starting to develop our app and so have no code to scrap.
