VS 2010 Mapping A Dataset?
Aug 11, 2010
I have to change an application I was made, but I have a big trouble.In this application, I use a SqlServerCE file, as database.But now, I need access the database from another PC.
I will made this:
- Create a XML file, with the location of my .SDF file
- The connection string, form making SQL commands is easy adjustable.
- The problem is: And how can I change the dataset automatically created form the VB? use it many times, in many forms, and in the application load, I have to read the XML file, and update this dataset.

[Code] i need a way to screen each employer status and mapping status before placing them in the DGV. I need to convert the numerical values to their corresponding status. 1 = Good, 2 = Non-Reporting, 3 = Under-Remitting and 4= Non-Remitting(which i already know how to do). I just don't know how to get the values being placed on the DGV. I would love to do this on oracle but i don't know how to.

I am using Access 2010 and VB in VS2010.I have created a DB and have several tables. 1 table in particular called Employers, has the normal AutoNumber Primary key. Everything in Access runs fine. I used Access to develop a basic model application of the full version I am developing in VS.My VB front end contains a dataset linked to the employers table. I have dragged onto my form the "detail" view of this DataSet, not the DataGridView. The usual controls are in place such as the EmployerBindingSource, EmployerTableAdapter, TableAdapterManager and a EmployerBindingSourceBindingNavigator.On my VB form Scrolling through the record set is fine and all works well.My problem is after I click the "Add" record button on the EmployerBindingSourceBindingNavigator. The form fields go blank as expected awaiting user input. However, the field that is bound to the employer_id field (the Employer table's primary key) shows a value of -1.The insert command works no problem, and having looked at the database the table contains the new record with a correctly incremented PK

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 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.
a.template = jQuery('#txtTemplate').val();
a.value1 = jQuery('#txtValue1').val();
b.var1 = jQuery('#txtVar1).val();

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.

I am using Fluent NHibernate to map an Oracle database. It is a legacy database so I cant really change everything I want.There is a GUID field, but the keys are still composite (I will change this as soon as I can so that the keys are not composite, but I cant do it right now). The GUID is a VARCHAR2 field with this layout: 551608b1-275d-49f6-9561-44d01aacf23f. The GUID is not added by a sequence in Oracle, but inserted from code (C# or VB.net)[code]Is the problem that I dont use a sequence to generate my GUID? How can I overcome this?

I have a read-only mssql-view, and I want to map it to nhibernate (using hbm.xml files). The view is a select that joins two tables. For give an abstract-insight, the select is something like this:
SELECT A.Id As A_ID, B.Id As B_ID,
A.AttributeA, B.AttributeB,
FROM A INNER JOIN B ON
A.Id = B.RootID
It's a one-to-many relationship between A and B (B entries are dependant/leafs of A entries).
I'm using nhibernate's hbm.xml files, and I can't make it to work. I'd gladly appreciate if someone can enlight me of the kind of XML that I have to use, I guess that as my view has no ID, I have to create a composite-nhibernate id (wich will be the ids os A and B together) but I couldn't make it to work. Also the view is READ ONLY so I think that should make the solution easier.

get data from xml and onto datatables within a dataset or if there is a simpler way i have completely overlooked.
1/ setup a dataset and add tables with columns ready for data
2/ setup various classes so i can construct a list (or array) of a specific type
3/ get the xml into an XElement type.
[code]....
Now i am wondering if i can say for the type in step 2/ use DataRow as the type thus missing out step 5/ ? is this possible? what other ways are there to get xml into a DataSet? One other method that occurs to me is to load the xml directly into the datatable (this is possible?) but i am not sure what the xml needs to look like for that to work. My xml is simple it contains only values and no parameters if that helps...
I require my final dgv to be sortable by column clicks etc so needs to comply to various interfaces, any pointers on this (perhaps i can avoid using a dataset and populate direct from my DataObjects so i only need steps 2, 3, 4, 5 and 7?)
