IDE :: Application With Multiple String Resource Files (not Localization)?
Apr 9, 2009I have a question abour string type resources and hope this is the proper place to ask it.I know how to create a string (type) resource file. I also know how one localizes this file by adding the appropriate language abbreviation (i.e., es, en, etc.) after the name of the file (i.e., str_resource.es.resource).None of this is terribly difficult. However, I haven't been able to fine how to do what I want to do.
Specifically, because I have an enormous number of strings (button labels, labels, registry strings [key_names and values, etc.), error messages and such) I would like to create multiple string resource files - one for each of these items. For example:

Storing A Database Connection String Into Settings In A .net DLL Data Layer?
Mar 4, 2011I've always used this approach while implementing data layer DLL for web application:
1) put datasets into the dll project
2) use a helper class with a method like this:
public shared sub settCnnStr(strconnhere as string)
My.Settings.Item("connectionString") = strconnhere
end sub
3) when I need to use the dll I call a method like this (usually into global.asax):
xxxxxxx.helper.setCnnStr("yyyyyyyyyyyyyy")
This method always worked for me nicely but I'd like to know if this method could have serious drawback or if there's a better solution.

Oct 7, 2009I seem to have a huge issue right now trying to grab different pieces of a string to place them in a different order in a list. Unfortunately i can't just find the placeholders for the strings and extract the data that way so i was using indexOf to find commas in the string provided. the problem i'm having is that i can assign the first comma and extract 0 - "," but i'm stuck on how to progress the indexof so it will move through the string submitting everything between the comma's.

Finding Resource ID Or Index Of A String/icon Resource?
Mar 4, 2010I need to refer to some strings using an "indirect string" in the registry. It should be in this form:
@filename,resource
MSDN: "If the resource value is zero or greater, the number becomes the index of the string in the binary file. If the number is negative, it becomes a resource ID."How can I find out either of these numbers for my resources that only have names in VB? I also need the ID/index for the exe's icon.

Oct 20, 2009I have the book "Visual Basic 2008 Step by Step", I am in the final chapters and have completed all of the walk through and demo programs thus far. I am a beginner but I also have a basic understanding of quite a few program statements and objects. My Goal: For the sake of simplicity I will use an example. I have a Tetris game, the player loses in the first level earns 25 points they click the save score button. , they play again tomorrow and do 1,000 levels and earn 25,000, now their score is 25,025.
Then they play my blackjack game, they gain 25,025 points when they start automatically from their Tetris game, they earn 25 points in blackjack click a save score button, now they have 25,050. [Thus far I have 2 games, and they both share a score that will need to be added to in the future]

VS 2008 : Storing And Calculating Data Into Hashtable?
Dec 11, 2010I am making a small tool that require some calculation. I am using hashtable to store values that I need to calculate. This tool continuously extract data on specific time interval(30 seconds) from webpage and add those data into the hashtable. Now the problem is I need to store the previous extraction data and when new extraction occurs, I need to deduct the previous data from new data.Here is the process I am currently following:
HTML
Dim MyTable as New Hashtable
MyTable.Add("Data1","200")
MyTable.Add("Data2","100")
[code]....
On first run it shows the result of Data3 = 100 which is currect. But on second run I need to redefine the value of Data2 = Data1 . So I need a result of Data3 = 0 on second run. This may not be the proper way to do this sort of operation. I have also tried using listbox, listview and even textfile to store the Data2 and recall that on second run.

Mar 16, 2010I'm trying to add functionality to my application to let user define "custom actions" in one of the context menus.Essentially, these would be command lines that can be executed against remote machines.I've got the code to add the menu items working but I'm not sure of the best of storing the data related to the menu items. At the moment I'm using a Specialized.StringCollection in the project settings but this only allows me to store a single line (i.e. the command line).This means that the text of the menu items is whatever command line the user has defined (not ideal).What I would like is to have a "friendly" name for the menu item (e.g. Start Notepad) and have that associated to notepad.exe.What's a good way to store this data so that I best dynamically build the menu items every time?

Sep 3, 2009My xml files were looking a bit clumsy when i read them, what i have done now is to save them in the xml in this format:

i noticed {|} this is the format that vb.net uses for arrays, i was wondering if that's an ok way to store things, on retrieval once i get the node value, what would be the best way to break up the {value1|it's partner value2} variables to use, explode the | and get parts (0) and (1)?
VS 2008 Which Method Would Be Faster For Gathering And Storing Data
Nov 16, 2009I have a simple multithread application that stores updated data from a list of websites. After each thread gathers data, it then store the data into the same text file. I am now thinking of having each thread store the data directly into a arrayList, and after a certain amount of time past, store from the arrayList to the text file. Which situation would enable the application to complete its task faster?

VS 2008 Write Data To Resource Or Alternative?
Oct 22, 2010Well this listbox contains sensitive data not very important but i dont want the end user to be able to see what the listbox contains, therefore i have hidden the listbox But my question is how do i store this information i could easily write it to a text file i know but the user could locate the text file. So i attempted to create my text file as a resource and that failed as i can read from it i cant write to it. More simplistic question. I have data i need to save from a listbox but if i save it as a text file the user could still access it and i dont want the user to be able to acesss the file i would like it to be internal because i also dont want the user to be able to delete the file?
View 7 Replies.net - Storing An Object To Use In Multiple Classes?
Mar 23, 2010I am wondering the best way to store an object in memory that is used in a lot of classes throughout an application. We have multiple databases, 1 per customer. We also have a master table and each row is detailed information about the databases such as database name, server IP it's located and a few config settings.
I have an application that loops through those multiple databases and runs some updates on them. The settings I mentioned above are updated each loop iteration into memory. The application then runs through series of processes that include multiple classes using this data. The data never changes during the processes, only during the loop iteration.
The variables are related to a customer, so I have them stored in a customer class. I suppose I could make all of the members shared or should I use a singleton for the customer class? I've never actually used a singleton, only read they are good in this type of situation. Are there better solutions to this type of scenario? Also, I could have plans for this application to be multithreaded later.
Storing Multiple Arrays Into A List
May 11, 2011The scenario is:
1)A large 2 dimensional array (400,20)
2)The program needs to access particular chunks(for example (0,20) to (50,20)
3)The program will open multiple files and process each into it's own 2D array (400,20)
What I have right now is code capable of creating the array, but no way to store the array so that I can open a new file and process that data into another large array. Someone mentioned the generics List(of T) might be a good way to store each new array as you could use the Add function. I have done some research on the List(of T) class but I'm not totally convinced that is the way to go. I'm just looking for some direction as I've just started on .net this year.

Starting Multiple Instances And Storing The Settings?
Jul 11, 2011I have a VB2010 application that must run as multiple instances on the same PC (it is a controlling/monitoring program of several devices, each instance of the program control one device)
Of course, the same application must save its own setting in different place, one for each device. For example, if I start the application for the device 3, I have to save the setting in a place marked as "3", in this way, when I start the application for device 4 it will load the settings for device 4 and not 3.
Of course all labels and similar stuffs must refer the starting device: i.e. the mdi caption must report "device 4", and so on...
In vb6 I created a shortcut with a command line and made my application accepting command line parameters.
In this way I could start the application passing the device number too. For example "myapp.exe 3" start my application for the device 3.
I stored all settings in several INI file, each one for a device: setting1.ini, setting2.ini, setting3.ini, ....
I was wondering if in vb2010 would be a better way to do that.
1. How could I start multiple instances?
2. How could I store the settings?
Storing An Object That Implements Multiple Interfaces And Derives From A Certain Base (.net)
Dec 7, 2010In .net, it's possible to use generics so that a function can accept arguments which support one or more interfaces and derive from a base type, even if there does not exist any single type from which all valid argument types derive. For example, one could say: Sub Foo(Of T As {IInterface1, IInterface2, SomeBaseType})(Param as T) And be allowed to pass any derivative of SomeBaseType which implements both IInterface1 and IInterface2. This will work even if SomeBaseType does not support Interface1 and Interface2, and classes which do implement those interfaces don't share any common ancestor that also implements them. This can be very convenient if one won't need to keep the parameter anywhere after the function has exited. Unfortunately, I can't figure out a way to persist the passed-in parameter in such a way that it can later be passed to a similar function, except perhaps by using Reflection. Is there any nice way of doing that?
The closest I've been able to come up with is to define an interface INest (perhaps not the best name-- thus:
Interface INest(Of Out T)
Function Nest() As T
End Interface
And for any interface that will be used in combination with others or with base-class "constraint", define a generic version as illustrated below:
Interface IFun1
' Any members of the interface go here, e.g. ...'
Sub DoFun1()
[CODE]...
A class which will support multiple interfaces should declare itself as implementing the generic ones, with itself as the type argument.
Class test123a
Inherits sampleBase
Implements IFun1(Of test123a), IFun2(Of test123a), IFun3(Of test123a)
End Class
If that is done, one can define a function argument or class variable that supports multiple constraints thusly: Dim SomeField as IFun1(Of IFun2(Of IFun3(Of sampleBase)))
And then assign to it any class derived from sampleBase, which implements those interfaces. SomeField will implement IFun1; SomeField.Nest will implement IFun2; SomeField.Nest.Nest will implement IFun3. Note that there's no requirement that IFun1, IFun2, IFun3, or sampleBase share any common derivation other than the generic interfaces inheriting from INest(Of T). Note also that, no matter how many INest-derived interfaces a class implements, it only needs to define one implementation of INest(Of T).Nest. Not exactly beautiful, but there are two nice things about it: (1) any concrete class which in fact implements the necessary interfaces can be assigned directly to a field declared as above, without a typecast; (2) while fields which chain the types in a different order are not assignment compatible, they may be typecast to each other. Is there any better way to store something in such a way that it's "known" to support multiple interfaces and derive from a certain base type? Given that one can write such code in a type-safe manner, it would seem like the .net 2.0 CLR could probably support such a thing quite nicely if compilers offered a little assistance.

Storing A String To An Array String

4. The string that I got was 192132456
Problem: Now I want that the I should be able to reverse the string such that the string should become 5624132901. I have tried using the arrays but it gives me an error when I try storing a string into an array. I am pasting the code below:

However, it's getting cluttered and I'd like to separate images into multiple resource files if possible. I created a new resource file, but Visual Studio doesn't recognize it when I go to the form designer and try to change an image. The only file that comes up under the Project resource files available are MyProjectResources.resx. The one that I just created isn't there.
View 1 RepliesVS 2010 : Finding And Storing A String?
Jan 8, 2010I'm obtaining data from a StreamReader.My StreamReader is called "reader" and I'm reading the stream with "responseOutput" like this "responseOutput = reader.ReadToEnd()" And in that bunch of text that I receive I want to FIND and EXTRACT a piece of text and then STORE that extraction in a variable of String type.Here is part of the code I'm referring to:
Dim response = request.GetResponse
Dim responseOutput As String
Dim reader As StreamReader
reader = New StreamReader(response.GetResponseStream())
responseOutput = reader.ReadToEnd()
And here is the text or data that I'm receiving (what I'm about to show you is the result of a "MessageBox.Show(responseOutput)":
