Is it possible to have an internal XML dataset within a VB 08 program I ask because we at present have the program load an external XML on startup, but i would prefer this to be internal withing the program to stop other editing the XML file.
View 6 RepliesI'm writing a VB.NET app where I want to load an internal text file from Resource. But the code shows Invalid URI: The Uri string is too long. The code is
'document.Load("C:UsersSouDocumentsVisual Studio 2010Projectsinfo.xml")
document.Load(My.Resources.info)
'some processing job with XML node ...
So, how to load the resource file ?
I am starting a application that will need to use a usb or included device camera to capture images. I would like to know if there are any samples or examples on how to connect to the camera and capture images. This will be using vb or c# dotnet 4.0 on vista.
View 4 RepliesMy issue involves relationships and cascaded effects between properties, and I'm wondering what best practices are on this.I have a class that contains a list of varying length of numbers. When editing the list, sometimes the user prefer to set a TargetSum, so that the program enforces the list will always add to this sum. I am accomplishing this by programmatically setting the final element in the list such that list sum = TargetSum. For example, if the user chooses to UseTargetSum, then sets TargetSum = 10, then creates a list of length 4, and enters 1, 4, 2 for the first 3 elements, then the final element is programmatically fixed to 3. The user cannot change the final element themselves.
I do this behind the scenes by handling all necessary events, such as a list element value change, list length change, and the UseTargetSum option change. For each event trigger, it recalculates the last element's value.It works but then there was a bug when loading saved data. If a list is loaded by sequentially adding the elements, the handlers modify each entry. Regarding the example, when the first value of 1 is entered, the handlers say "a value was just added, the sum should be 10, there is currently only one element, so it needs to be 10". So the first element gets changed to 10 behind the scenes. When the second element is next added, the handlers say "a value of 4 was just added, but the first element is already 10, so it should be zero." At the end of the load, the final list reads 10,0,0,0 instead of 1,4,2,3.
I know it is possible to rearrange the load procedure such that I get the correct list. For instance, I could avoid enabling the TargetSum event handlers until after all the data is loaded. The list would first be created as 1,4,2,3 and then the handlers would change nothing.
But this experience makes me wonder if I am opening the door for other sneaky side effects. It seems you should be able to load data without worrying too much about an implicit ordering. It also seems unusual to have "cascading" effects between class properties. Is there a more accepted approach?
The other alternative I'm considering is to only enforce TargetSum only inside UI forms. Ie, when you know it's a user making the change, then enforce the TargetSum, but otherwise leave the core class logic alone.That way database loads, etc, are left unaffected. But I guess the downside of not having ubiquitous enforcement is that opens the door of incorrect sums via some unforeseen complication.
I'm using Visual Basic .Net 2010 Express.I know, for example, that the Visual Basic ( IEEE 754 ) Internal bit-by-bit Double Format is: Bit 63 = Sign, Bits 62-52 = 11-bit Exponent, and Bits 51-0 = 52-bit Fractional Significand.But, I can't seem to find any documentation on the Internal bit-by-bit Decimal Format.There also don't seem to be any workable mechanisms for accessing the bit structure or copying the bits to another Format for internal processing and returning the result to the Decimal Format.[code]to separate the ULongVariable into bytes for convenient manipulation. A similar reverse process allows moving the manipulated bits back into the Signed Long Variable.But, methods like << and >> are not extendable to Decimals per the Microsoft Documentation ( and I tried them anyway, and confirmed that they don't work ). Nor does there appear to be any way to copy the 128-bit Decimal into two 64-bit Unsigned Long Variables, or vice-versa.
I could, of course, forgo the use of Decimals and define my own MDJDecimal consisting of two ULongs, but that seems a bit of an overkill, and its methods would likely incur significant development time, and would probably also be rather excessively slow and cumbersome.I know I could write a workable routine in Visual C++ .Net using the Unmanaged Native Assembler, but I don't know enough about how to integrate that with Visual Basic .Net code, and I don't want to irrevocably tie what I'm developing to the Intel platform.I might also be able to write it in Managed Visual C++ .Net, but, again, I don't know enough about how to integrate that with Visual Basic .Net.
I have some forms that were VS2005 forms the I moved to VS2010. The forms have a tab control and on the tabcontrol are some panel containers. If I add a multi-line textbox toa panel I'm seeing the text offset from the left margin. If I make a form from scratch the margin does not appear.Any idea where this left margin is coming from?Is there a way to set the left internal margin in code?
View 9 RepliesI have several VB6 exe's/dll's that I have created, when I right click on the file and get the properties it says:
File version - 4.2.0.9
Product Version - 4.02.0009
Is it possible to change the File Version? I want this to say 4.2.9.123
I want to change this programmatically, so where is the file would I find these values? Are they at a specific location?
Is this going to cause an issue registering the exe/dll's with COM if I change the internal version?
I'm trying to connect to a remote server (from our customer) via HttpWebRequest.GetResponse but at the login page i'm always getting an exception: "The remote server returned an error: (500) Internal Server Error."

View 1 RepliesIts been a very long time since I don't show up here.Now I am back with a small project for internal use, but I need a little help.I want to make a program that allows me to change file attributes, like 'hidden', 'read-only' and 'system'.It seems pretty simple, but I want that multiple files can be modified at once. For this I would need a list that shows the files into the interface. There is what I can't get.
I first thought on a listbox, but there is also a listview which seems much more complete, but I just don't know how to use it. I was wondering if I could make something like: I open a folder, all the items inside that folder would be listed inside the listview.I learned a bit, but not enough. I've set the listview to 'details' mode, so I can actually list items. Also, I've added three collums: one for file name, other for file size and another for file attributes. I just need to learn now how they works.
Recently, I have a requirement to develop a vb.net application wherein the input excel sheet data which has an average of 5000 records should be checked for Internal duplicates (duplicates within the same sheet) and external duplicates (duplicates which exist outside this sheet). I have gone through lot of logics..some of which are ...
- Common and currently testing out..
- First insert the excel sheet data into DB..then query by following
select distinct id,mobilenumber from scrubmaster where calltablename=<calltablename given by the uploader>
Then loop for duplicates...

The above logic works but it takes very long time..I have tried other logics from web but they "Query timeout"...
I know this is old hat, but when you're faced with a problem you cannot solve yourself, you need to find someone with the correct answer.In short, go to the wise.
I am working on an application that has a lot of records, and it uses a listbox control bound to a binding source attached to a table in a data source.A new record with data is added to the binding source's attached table, and, of course, to the underlying sqlServer database table:

View 14 RepliesVB.NET doesn't have out parameters, but you can specify <Out()> ByRef on COM and P/Invoke methods to get the same effect for external methods.
Does specifying the same on internal methods (i.e. methods only called by .NET code) actually help the Jitter (or VB.NET compiler)? Or is it currently only useful as a programmer note.
Is it possible it could be used in a future Jitter, or is this attribute lost when compiling?
If I have a module in a VB.Net class library, will it's visibility be limited to the assembly? What I'm looking for is the VB.Net equivalent of a C# internal static class.

My software run perfectly on most computer which has the latest Flash player, but not worked on some PC even has the latest Flash player. I am thinking to include Flash library into my installer, so the user dont have to install the Flash player.
My question is how to make my software to use my own Flash library without accessing to the Flash player inside their computer, so my software can run perfectly without the user have to install Flash player. I want to make my software easier to use without asking the user to install Flash player.
