I am writing an application in VB.NET 2008 that manages software deployment and I want to display a "deployment overview" grid.
The grid will be populated with the names of each application (top row) and the name of each workstation (1st column). The remaining cells will be populated according to whether the corresponding software title has been installed correctly, install failed OR not deployed.
What would be the best way to present this information to the end-user? Could the application 'cope' with maybe a thousand check boxes or would it be better to 'owner-draw' a grid in some way?
I may also require the ability to click on any of these cells to view and/or set other properties.
Many thanks for your help.

I have used the .NET's GridDataView without any problems using the Virtual Mode while trying to show over 10000 rows but there are good products out there that are also very good in loading tons of data like Developer express XtraGrid and Telerik's RadGridView.
The only challenge was keep the UAT people happy with all the noise from several thousands of rows.

I'm trying to determine the best way to utilize SharePoint 2013 to manage a very large project with a number of hierarchical elements. I've thought about using cascading/embedded group permissions (doesn't appear to be possible), audience targeting (I'm concerned about user's ability to understand and correctly enter the appropriate target audience), using some kind of session variable fed from a SharePoint list to determine how to characterize entries but then I need a way to auto filter them in lists (seems awfully complex and not sure this will even work). So I'm wondering if I'm missing a better way to do this. This being the following:
I have various staff levels: people at the bottom who are located at a site, a person at the site that is the manager, a hub that links various sites, areas that oversee hubs and include an area manager. I'd like these various people to be able to see only whats relevant to them so for a simple example: a list with a calendar view. An area lead should be able to see all entries made by his site leads, while a site/hub manager should only be able to see entries made by people under their respective site/hub. This would work perfect if I could assign groups to groups and then filter the list instead of by [me] by [(some permission filter option)]
There has got to be a simple way to do this, anyone have any ideas? I think I'm missing some capability of SharePoint 2013 to do something like this and thus am making it harder than it should be.
I'm beating a dead horse here, but I still haven't found the answer I am looking for. I am throwing together an Access Database that deals with lockout procedures for our various machines at work. I have a continuous form setup so that it dynamically populates based on various complex/machine criteria. Since only portions of the machines need to be locked out at a given time, it is necessary to select the various devices from the list that was populated dynamically. When users select the various devices that they wish to lockout, they will then be able to automatically print tags for the selected devices. Which is where the unbound checkbox conundrum comes in... Yay!!!
Since it is possible for multiple users to be using the database at a given time, I don't believe that binding the checkbox to a yes/no selection within my table is the correct path to take. This is due to the fact that having multiple users picking various devices would result in additional/unnecessary tags being printed out to each user. I know that it's possible to have an unbound checkbox within a continuous form, but I have not come across any sample code that has this functionality.
If there is another path that I can take, please offer any suggestions as I am an Access novice, and am open to new ideas.
EDIT
I should mention that the database will reside within Citrix. I am not sure if this affect anything, but its worth mentioning at least.
I am assuming that you are using a client server setting, where the application file resides on a local machine. (Or on a local instance in the case of RDP / Citrix)
In that case, you can have a local table to save the checkbox information without causing any conflicts between users.
You will be using a bound checkbox, so problem solved.
Sorry for the insanely long title, I find this one hard to sum up. I'm being asked to maintain several internal-only web apps for my company. For testing, after making my changes, I've created some staging sites which make use of separate databases. As such, if my users were to mistakenly use this site as if it were the production site, they may enter important data and wonder where it "disappeared" to thinking it was the production server.
I'd like to create a big banner of some sort across the top of the staging site (which ONLY appears on the staging site) to remind my users that they are on the test site. I'd like recommendations on the best way to do this, with the following considerations:
IDE: Visual Studio 2008
Server: Windows 2003 with IIS 6
Language: VB.NET 2.0
Thanks ;)
I would create a web.config app setting that contains a specific value in staging. Then in your master page(s) code behind(s) - assuming you're using them - write some code in that inserts an appropriately styled HtmlGenericControl (as a div) into a PlaceHolder control in the master page markup. All this occurs based on whether the app setting has the value indicating the staging environment.
If it were me, I'd make the staging site have a different color background.
White background -- public and live.
Pink background -- staging, liable to be reformatted any second.
I need a simple tool to visualize the status of a series of processes (ETL processes, but that shouldn't matter). This process monitor need to be customizable with color coding for different status codes. The plan is to place the monitor on a big screen in the office making any faults instantly visible to everyone.
Today I can check the status of these processes by running an sql statement against the underlying tables in our oracle database. The output of these queries are the abovementioned status codes for each process. I'm imagining using these sql statements, run periodically (say, every minute or so), as an input to this monitor.
I've considered writing a simple web interface for doing this, but I'm thinking something like this should exist out there already. Anyone have any suggestions?
If just displaying on one workstation another option is SQL Developer Custom Reports. You would still have to fire up SQL Developer and start the report, but the custom reports have a setting so they can be refreshed at a specified interval (5-120 seconds). Depending on the 'richness' of the output you want you can either:
Create a simple Table report (style = Table)
Paste in one of the queries you already use as a starting point.
Create a PL/SQL Block that outputs HTML via DBMS_OUTPUT.PUT_LINE statements (Style = plsql-dbms_output)
Get creative as you like with formatting, colors, etc using HTML tags in the output. I have used this to create bar graphs to show progress of v$Long_Operations. A full description and screen shots are available here Creating a User Defined HTML Report
in SQL Developer.
If you just want to get some output moving you can forego SQL Developer, schedule a process to use your PL/SQL block to write HTML output to a file, and use a browser to display your generated output on your big screen. Alternately make the file available via a web server so others in your office can bring it up. Periodically regnerate the file and make sure to add a refresh meta tag to the page so browsers will periodically reload.
Oracle Application Express is probably the best tool for this.
I would say roll your own dashboard. Depends on your skillset, but I'd do a basic web app in Java (spring or some mvc framework, I'm not a web developer but I know enough to create a basic functional dashboard). Since you already know the SQL needed, it shouldn't be difficult to put together and you can modify as needed in future. Just keep it simple I would say (don't need a middleware or single sign-on or fancy views/charts).
I'm building an application that runs on a Windows Mobile device. I'm using Microsoft's Sync Framework to sync the Sql CE database with the main corporate db.
The question is how can I limit the fields that are syncronized? The table in question has stacks of fields but I only need to display a few of them on the mobile device and replication is only one way (from the server to the mobile) so that shouldn't be an issue. I've seen this similar question but there's not much info there. Can anyone give me more advice on how to achieve this? I imagine that it's a very common requirement.
Also, does anyone know if I can use the Sync Framework Version 2.0 or do I have to stick to 1.0. I had a feeling that 2.0 doesn't support Windows Mobile but I'm not sure.
Cheers

You can change the T-SQL that's generated behind the scenes to not include all the columns of the table, but there are a couple of gotchas here. Firstly, it means that you can't use a wizard to modify the sync selection later - not a big deal, and creating your own partial class to override just the specific method with the T-SQL for your table mitigates that a bit.
Second, changes to the unincluded (not sure if that's a word?) columns can also trigger a download of that row as by default the change tracking is by row. You can change this by setting the Track_Columns_Updated flag
ALTER TABLE Employee
ENABLE CHANGE_TRACKING
WITH (TRACK_COLUMNS_UPDATED = ON)
Depending on the number of rows and size of the data and frequency updated, I have often found an easier solution is to provide a trigger on the main table of the server to update records in a separate table containing just the data you need, then sync that. It makes it much easier to change what's downloaded later. This is obviously not a solution if you are downloading the entire works of Shakespeare, but for a few 1000 records of a product catalogue, I think it's perfectly feasible.
