Difference Between Mapping An Exe And Installing Separate Client Software?
Apr 30, 2009
I have seen many good inventory software were having a server and a client software.
My Pm ask me to install the software in server and map it to other clients.
if we map it we just need to update only one exe in server, but if we install the client software in all client machine, it needs to install in all machine, which is some heavy work.
what is the difference of mapping it and installing a client software itself on each machine ... ?

I am installing an application on a client machine. The application is throwing an exception that I am logging that states "Class Not Registered". This an app written in Visual Studio 2005 using VB.NET. The dll dependencies of my .exe are located in the same folder as the .exe. What class is this talking about and how can I resolve this issue?

I have an application in which i have a database .mdf file in directory which i use a connection string to give a path of to access it, which means without installing sql server i can access database. Connection string below to access this database(.mdf) which placed in the directory.
dim con as sqlconnection = New SqlConnection("Data Source=.SQLExpress;integrated security=true;attachdbfilename=|DataDirectory|Universal_data.mdf;user instance=true")
Now the question is that if i access this .mdf file without installing sql server, i also want to access to this .mdf file on other computer(client) after creating DSN or any other connectivity tool.
Let me know you that when i install sql server 2000 or 2005 i create SA user name and password which i use to create DSN on client computer and give SA username and password in the connection string that successfully works and client get access to sql server, connection string is below.
Dim serv = "MY-LAPTOP"
dim con as sqlconnection = new sqlconnection("Data Source=" & serv & ";Initial Catalog=clinic;Persist Security Info=True;User ID=sa")
I only need to know that my application access .mdf file without installing sql server works fine on a single computer, and i want to give access to this .mdf file on other clients without installing sql server on server computer (like i mentioned above paragraph) how will do it.....

I wrote a VB code to call a sp in sql server 2005, which returns a recordset as follows:Dim objRecordset As ADODB.Recordset Set objComm = New ADODB.Command
Set objRecordset = objComm.Execute If Not objRecordset.BOF And Not objRecordset.EOF Then
Set objRecordset = objRecordset.NextRecordset I need to continue to get next recordset since there are many select statements inside the sp which I need to get the data. The code works fine when I create the DSN using SQL Server but it does not work when using the connection string or SQL Server Native Client DSN. It either breaks at Set objRecordset = objComm.Execute ( connection string )or at If Not objRecordset.BOF And Not objRecordset.EOF Then(SQL native client )
I have worked on this for a couple of days now and could not figure it out.Is this a bug in SQL Native Client or something related to some configuration on the database side? IS there a way I can change the connection property to get this working using SQL native client or connection string?

I created a telephone number form where the user enters the telephone number in a text box as (nnn) nnn-nnnn. The first 3 digits in parenthesis are the ISD code, the next three are the area code and the last four are the local number. I need to separate out these three fields of the phone number and display in three separate text boxes labeled appropriately. Now, suppose the user enters the phone number in a text box as a continuous string of 10 digits, where the first three represent the ISD code, the next three represent the area code and the last four represent the local number. I'm lost as how to change this string into the form (nnn) nnn-nnnn. This is what I have

I have a TabControl object on my form with many tabs created in code (TabPages) and my problem is that the same objects that are in the initial TabPage needs to be in the other TabPages created in code, I have this done in code when the user clicks the 'New Tab' menu option, however the same code is used for any new tabs created. The problem created here is that I have an event against one of the objects that appear in the other TabPages, but because the same code is used to create any new tab pages, the event will only work on the newest tab page, if that makes sense? By the way these objects that appear on the other TabPages are properties at the top so events can be handled against them in the respective subroutine.

I'll get straight to my problem - I'm currently coding in Visual Studio.I have a table (countries) with the columns ID | Name. The table is filled with around 28 records.I also have a form with 4 combo boxes (set up as 1,2,3 & 4) that I want the user to select. These combo boxes will display the names from the table countries. I then want to use the selected names in the combo boxes to Insert into their corresponding ID into another table. For example England would have the ID 1, USA the ID 2 etc.So, is it possible to have separate combo boxes that will give separate ID values but using the same table? At the moment I can't seem to find a solution.Eventually the form will have more than 4 combo boxes so I don't want to use separate bindingsources for each combo box.

We are creating a Who wants to be a millionaire style game in VB. Our server is pulling information such as questions and answers from a Access Database and sending them to the contestants (Clients). All transfer of information is directly from the server to each client. One of the "Life Lines" we want to use is "Ask a friend", where one client is able to Instant message another client for a short time to get help on the question.

I have a few forms that have a lot of really intensive updating along with a great deal of user interface (text boxes, button clicking etc) Is it possible to open a separate form as a separate UI thread from the start up form that called it to "show" or open or whatever the new method might be?

Using automapper i am mapping my ViewModel to my business object, however i want to map to an existing object instance and only map the properties on my view model. e.g.
ProductModel has id,name,code
ProductBusiness has id,name,code,dateadded
Function Add(ByVal model As ProducModel) As ActionResult
[code]....
i want to somehow pass in the existing business object instance and only map the 3 properties that are on both objects, dateadded should stay the same as it was in the database.

I have a form with a button that says "Open CSV".I want to be able to click that button. Then browse for a .CSV file, and after I select the file, populate a combobox with all of the headers of the .CSV.I would then be mapping these headers to fields in my database, then import the .CSV data into my database.

The issue I'm currently having is mapping multiple GUI fields to object properties (i.e. Presentation layer to Business Logic Layer mapping). To be more specific, this is in VB.Net 2.0 WinForms. The nature of the solution requires us to have 4 columns which exhibit the same type of behavior on our GUI - each column consisting of 11 textboxes (we'll just use this small sample size, as the problem extends beyond 11 textboxes).
What I am currently doing is setting the tag of each textbox in all four columns to a value like so:
Textbox1.tag = "name"
Textbox2.tag = "type"
Textbox3.tag = "speed"
[Code]...
As you can see this can get very bad, rather quickly. Currently we're setting 43 some odd properties that can be mapped to -- thus that select statement is extremely long -- many of which are embedded in multiple methods to try and attempt DRY (I've watered down the code to essentially a conceptual implementation).
Question is: how can I refactor this? I've attempted using a dictionaries/hashes to a certain extent, but it either became overly complex, or just plain didn't make an implementation sense as it convoluted the problem even more.

I have a very long list of points I would like to plot on any state in the US. I would prefer to plot each point with just a dot. All I have is an address that includes the street address, city and state and possibly the zip code. Ideally, I would like to place the resuts in a VB Picture box. I understand there is a Google interface but have found in my research the examples to be lacking exactly what I need.

what options do I have for creating a VB.Net application with a mapping framework; obviously I am not going to write my own. So is there any OFFLINE components free or otherwise that I can use?
Application Background : Basically I have a mobile device that sends its location back to a socket server (I am writing using .Net sockets) every 10 Seconds (possibly longer 10min, not decided). The client (which I will also write and need the map component for) will login to the server and download the latest number of GPS points and simply plot them onto a map surface (thus the maps need to be of street level quality). Although the map database can be updated over the internet, I have to assume the user does not have an internet connection. So using something like Google earth is no good. Initially I need the UK only, but will need the option for Europe and possible the USA later on.

I have been reading through Atheists posts in regards to client-server and TCP client/server connection's. But how do i go about writing a program with 1 client and server where the client side creates a text file.Once the server sees there is a text file it connects and downloads it to itself or the client pushes the text file to the server.Once on the server i will read the text file and put its info into a sql db.

I have an application that takes a series of reports and sends them as attachments in an email to a specified group of email accounts.
When I run the Java version of this using apache commons and the same setting, the email is sent. However, when I run the VB.NET version of the code, it fails on my local machine and on the client machine.
I have a VB.NET web application running on a server that uses similar code. I tried that code locally and it fails. Yet, the web application is working perfectly.
Why is it that the Java application can send the email, but the .NET application cannot?[code]....

I have a problem with my code. My code is using the fileupload control to browse for a filename when you add a filename it processes it and the code runs fine on when it lives on local host, but when I put the code on our prodution server it cannot find the filenames listed by user.
For example if I use the upload control to browse to B:MISCH IntiveRPTTOFL_3.csv and the code lives on my localhost which know what that file path means it works, but if the code is moved to a production server it may or maynot know what B:/ is or B:/ maybe mapped to something else. Even if I am browsing to a file on my C drive it will work on if the code is on the machine that the C drive is on, but it will not work if the code is on another machine because obviously that file wouldnt be on that C drive.

I have a situation where a class's properties are being exported/imported from an Excel sheet. Each property is in a specific column, so I want to make a mapping between each property and column # (a Dictionary collection would be sufficient). That way I can just loop through each property and/or column in the dictionary when read/writing data (maybe something like Class1.PropertyA = ws.Cells(curRow, Propto ColDictionary(PropertyA???).value). But, you obviously can't treat properties like other value types, so I don't know how I would store a property in a dictionary for this purpose. So could this sort of thing be achieved via reflection, or am I off-track?

I am passing a pair of serialized objects into a vb.net webserviceThe first one maps to a known structure, so I am using the structure type in the parameter list of the webservice. The second object may map to one of 6+ structures.A field in the first object will tell me which structure to use for the second object once both objects are passed to the webservice.

I'm developing an application that needs to Map a network drive for a domain user logged into a domain PC from a remote location. I have tried numerous different things with different levels of success but none with the required functionality. - First, I used WMI to create a process that would run Net Use with no luck: Net Use would ask for a user name and password to connect to the share instead of using the User's credentials.- Second I generated a script (wshNetwork) that would be copied to the remote PC and used WMI to once again create a process that would run wscript in command prompt to execute the copied script.
The script would run successfully (as evident by code placed to fill in a text file when the script completed) but the network drive was not added.- Third I created a program that would be copied to the user's PC which would map the drive using Windows Network API. Again, I used WMI to execute the program as a proccess with the results the same as the script. The application would run successfully but the drive was not added.- Fourth, I edited the user's registry to add the drive. This worked, however the mapped drive was not usable through Windows Explorer without a reboot.
Unfortunately, one of the requirements of the application is to avoid rebooting the remote PC.I have arguably had the greatest success with the following:- I used WMI to generate a scheduled task on the remote PC that would run a script (wshNetwork), an application (Win API) or the Net Use command to map the drive. All resulted in the drive being properly mapped and visable through windows explorer with the files accessable. However, the new map would be labeled "Disconnected Network Drive" and the drive could not be removed (error: network connection could not be found) and the driver letter could not be used without rebooting the system. Anyone have any suggestions on how I can do this? Unfortunately I can't use wshController to run a remote script because a majority of the PCs on the domain are not configured to use it.
