If I took a COM object (specifically Excel 2003 workbook) and made it an embedded resource of my executable, would that improve the notoriously slow .NET-COM interop at all?
View 1 Repliesi'm developing vb.net application. There are 10 ways of transactions. I want to produce 'Purchase register report'. For that I want to find what amount of effect has been made by each transaction on ledgers of 'Purchase account'. Purchase account has almost 30 ledgers. And transactions can produce about 10000 rows in database for a year. Now if I produce month wise report for a year, there will be 10000*30=300000 row scanning which makes it very slow in execution.
View 6 RepliesI'm trying to improve my app with some error catching. I have a module that downloads a file from the Internet to a local folder. At the moment, if the local folder doesn't exist, it just crashes here:
strLocalFile = New FileStream(pPath, FileMode.Create, FileAccess.Write, FileShare.None)
with error:
System.IO.DirectoryNotFoundException was unhandled
Message="Could not find a part of the path 'C:Documents and SettingsSimonDesktop estdownload.zip'."
Source="mscorlib"
How can I do something with that error and stop my app from crashing? Ideally, have a messagebox show saying 'directory not found' or similar.

View 15 RepliesI have a repeater which takes 270 seconds to render and actually ends up crashing all browsers. The SQL to retrieve the data takes about 10 seconds. I wanted to remove the Eval's to see if that speeds up things a bit, but I am having trouble with the correct syntax. I have doubts that this would actually improve performance as I am dealing with 150,000 records. Would a GridView or other control be faster? Would using LINQ to SQL improve performance? Here is the code for the Eval:

View 5 RepliesI'm currently working with a gridview that has a huge underlying dataset.I'm almost certain that I saw something about a new facility in Visual Studio 2010/.NET 4, which would improve the performance (e.g. doesn't download all the data on databind, but rather only what data required for current page). My guess would be that it was using AJAX.I didn't need it at the time I saw it, and now I can't find it, even though I've been hunting online for a while.

i have added 3 .png files [done.png, failed.png, busy.png] to my project & changed them to "embedded resource" [from this wht i understand is that they will be integrated within the exe hence eliminating the dependency on the actual location it is stored]
i have 1 picturebox on my form whose image i have to change as per the output of something else
this is wht my code looks like :
If text1.text = "Done" then
picturebox1.image = my.resources.done.png
end if

I am wanting to use a vnc installer as an embedded resource, and if the computer running the program does not have vnc installed then typing in a password will install vnc. I have tried everything I can think of and running the process from my computer works, however when ran on a different computer i get the error "File not Found". I am sure I am not calling the embedded resource correctly. I am using Process.Start(" ightvnc.exe /S")

I'm having some trouble trying to inherit a control that uses an embedded resource. The trouble is - this control uses me.GetType() instead of GetType(ControlName). Now when I try to use the derived control, it looks for the resources in the derived control's assembly, instead of the base control assembly, and obviously - doesn't find them.

View 1 RepliesI've copied the files albanyc.ttf and MTCORSVA.TTF into 'Resources' and set the 'Build Action' for both to 'Resource'. A label is set to one or other of these fonts dependent upon what is being displayed. This works fine on this PC but when I copy the program to my laptop it seems to me that neither font is used and the same 'other font' is used in stead of either of the ones I want to use. I tried setting the build action to 'Embedded Resource' but that made no difference and I got an error message when I tried 'Compile' (I kinda expected that, but thought it worth a try). Both CP and laptop have the same OS, Win.7 64bit, the only difference is that the PC has Pro. and the laptop Home P.

I'm starting to learn about developing applications for eBay. You can pass queries to eBay in XML format, and receive replies back in the same format.
I have some examples of code to do this. Here's how the sample code loads an xml file, containing the query.

Dim xmlDoc As New XmlDocument()
Dim current_assembly As Assembly

I can't see any difference between the sample and my attempt.
The Assembly Name and Root Namespace in my project are both set to "Sample," just as in the original.
I've tried things like changing the filename and the namespace, but I still can't get it to work.
the story goes something like this:i have embedded resource file, a vbs script.i have an error when i use writeallbytes and it says dimensional error cannot be converted to bytes something like that so i decided to make a module instead of writeallbytes,what my program does is it writes the content of the script to textbox and after that this data will be written in a script and will be save on drive C: as .vbs.that is perfectly working on my codes

I'm not sure if I'm gonna feel like an idiot after posting this, but here goes . I have taken my first shot a writing a code generator. not too shabby for my first go round, but I already see some ways it can be vastly improved. Not there yet, however. One of the things this code generator does is pull text templates (MANY text templates! Over and OVER again!) from a project resource file. I have added them to the resource designer as linked text files.
Now, the way the generator is written, there can at times be a LOT of iteration (think writing property declarations for a Classs which represents a database entity, as well as the backing fields for those property declarations, etc.).
Is there any significant performance hit to repeatedly accessing a resource? I have looked around on msdn and this forum (and will continue to investigate), but I am hoping someone can give me some clarification.
I SUSPECT that use of a resource file means a trip to the Hard drive each time one accesses it . . . Right? It IS a FILE, linked by it's PATH, right? Due to it's having been designated as a project resource, id a resource file somehow "magially" made available in memory, so that the disk round trip is not necessary?
I suspect I should be retreiving popular resources into a persisted Class-level variable if I plan to use them often within a specific class scope, and at the method level if I plan to perform a significant number of iterations whihc require the resource within the method.
AM I on the right track, or is the resource retreival trivial? I am NOT concerned about milking maximum performance out of a generator tool; it is acceptable for this process to take a little time. However, I also don't want to be sloppy unecessarily.
My program toggles an existing IE add-on between enabled and disabled. At the same time, it creates a shortcut to itself in the Quick Launch folder using one of two icons which reflect whether the next click is a toggle on or toggle off. I store the two icons in the same folder as the targeted executable, and everything works fine, but I would rather have these two files embedded. I know how to embed them. The problem is locating them. At the moment I use:
Dim MyShortcut As IWshRuntimeLibrary.IWshShortcut
MyShortcut = WshShell.CreateShortcut(QuickLaunchVariable & "Toggle.lnk")
MyShortcut.TargetPath = path/executable
MyShortcut.IconLocation = path/iconfile
MyShortcut.IconLocation requires a string and I don't know how to get to the location of an embedded file as a string. There is no MyShortcut.Icon which would allow me to simply refer to the embedded file.
Our current solutions/projects have several classes combined into one file, I'm told this was done due to the slow compile times in VS
