recommend a zone ocr sdk package. What i would like to accomplish is to automatically import a set of images, pdf or jpg, and then apply zone ocr to each image to extract data into a database. I have already looked at and spoken to Lead Tools and it does seem like they have everything that i would need but by the time you add up all the modules / addons needed, the cost is just too high for our small shop.
View 3 RepliesI was wondering what books/items you guys would recommend to read in regards to VB programming and/or programming in general.

View 2 RepliesWe have a new build machine to start using for our programming team. We are still trying to figure out how we want to organize everything to get the best configuration for building EXEs and DLLs.
We are using VB6 and VB.Net 2005, and VSS2005.
We were thinking of making working folders set for each project, release and support tickets. Does anyone have experience with a similar set up? What were your likes/dislikes?
The main purpose of the my app that I need your help with is, to deliver an always (or close to) up to date a list of files for the user to choose from for a variety of common purposes. For instance, opening the selected file in its native client editor application so the user can make changes. Another purposes would be to print the file, and I have others.
If nothing else (meaning recommendations for a better design that still keep my desired in mind) I'd like ideas on how to update my complex DataSet (background processing options, what's the most efficeient/quickest way to update my DataSet) as the list of files changes while my app is running and my app is designed to never close due to the long amount of time it take to load it initially.
The list must be always kept up to date while my app is running because not only the intial loading of data takes a lot of time but updates (new/modified/deleted) could potentially take too long depending on not only how much data to update/add (new files) but how efficeient my code is in updating the list. To be perfectly clear: If a new file is created then it need to be somehow (automatically preferably or manually i.e. button code) add to the list. If a file is deleted then it needs to bet removed from the list. And if the file has changed, perhaps some of it metadata or thumbnail image have changes so update the file's data in the list. All of which (new/modified/deleted) need to be as real-time as possble without degrading the server too much and without the user waiting more than a handful of seconds.
Listing all the files as quick as possible whether that be with or without metadata initially is very important because most of the time the user is going to filter (or scroll the list by typing) for a partial file name. Once the user filters/scrolls to the desired file there's a very good chance that he/she isn't even interested in the metadata, most of the time the user wants my app to open the selected file in its native client editor application so he/she can view or modify the file. The initial
load time of the data doesn't concern me as much as updates because the user can possibly do other things while it initially loads all the data as long as it not too long (more than a few minutes). From there the updates will either be automatic if possible (most desirable from a users standpoint) or the user initiated (e.g. button). Plus I'm thinking the updates might need to be done with a few different background processes (multiple threads) because I think I need one for periodic updates (e.g. every
15 minutes) and one background process for page updates meaning whatever the user has either scrolled to or filtered for, more accurately all files currently display to the user will be systematically update in the background so the user can still operate my app.
I'm currently using SqlDataAdapter.Fill to fill a DataSet object variable (which is bound [BindingSource] to a DataGridview control) to first populate the DataSet from the SQL query and then prorgammatically adds records (DataRow) for local files but please make recommendations. I don't mind big changes or starting over if necessary, I just want the best app possible based on the aforementioned criteria. I'm not sure if it complicates matters but I've also added custom columns in the DataSet for some special needs (thumbnail of files, booleans for tracking custom statuses). For the local files I'm currently populating the DataSet prorammatically (iterating a path/file string collect made by System.IO.Directory.GetFiles) since the list is first (and very quickly) populated with Vault files (which is always a far larger list than the local files) so . Again, I don't have to take this direction, make recommendations.
I am a student a couple of weeks from completing my first Visual Basic class. I have a 100% score so far. Plus I am really enjoying the class and learning VB. We use Visual Studio Professional 2008 at school. I have also installed that product on my own pc from the DreamSpark site. I'd like to continue my education with VB. However, there are no classes this summer in VB at school. I was wondering if there might be some online tutorials or books that I could use to keep moving forward. I have good discipline for learning without being in a classroom.
Generally, what I like is something that shows the key points about a new topic. Gives an example of how the topic might be used in an application. Shows a code sample or two. And then gives programming assignments that use that topic. So that I can then write the applications. One of my educational goals would be to start through the Microsoft Certification process.
I programmed in Basic, Fortran and PL1 many years ago. I now am developing a complex Excel application that needs use of VB macros. I've recorded and modified several VB macros so far, but have gone beyond my skill level trying to use VB indexed variables that link back to a spreadsheet. What text/reference book would you recommend for my level of skill? I'm not trying to become an expert -- just need help with approaches and correct syntax to simple programming issues if, while, indirectly addressed variables, etc.

How do I change the time zone using VB.NET 2.0? I found an article explaining how to do it in VB6 [URL] but I can't adapt it to .NET 2.0 - I just don't have enough expierience I guess.
View 4 Repliesused the WMI ChangeZoneType DNS command in C#VB.net before. I get an incorrect parameter exception when i try and invoke the changezonetype command. I get the dns zone that i want to change from the dns server (via query), set the zonetype to the appropriate uint value but am then getting the exception. I am trying to change the zone from secondary to primary and according to MSDN all the other values are optional (and as far as i am aware are needed when you want to change from primary to secondary) so i have not included them.
Below is the code that i am using....

View 1 RepliesBasically I am looking for a means within a asp.net 2.0 (or higher) application, to identify a time zone and UTC offset for a specific location and date. I want to be able to look up the time zone rules using either city & state, Zip, or LAT & LON I have an event database that tracks location, date and time for the events. Times are recorder relative to the event and the records do not currenlty indicate the timezone for the event or whether or not DST is in effect. Recently, I have encountered a situation where I need to link several events across different time zones. What I am looking to do is:
first, record a master event, say for August 13 2012 at 8:PM in New York, NY 10021
Second I need to record a related event in Houston TX.
When I record the related event I want it to automatically populate the date and time relative to its local time time zone rules. To do this it needs to be able to identify the effective timezone and UTC offset for the master event as well as the linked event so that I can calculate the correct date and time to display on the satelite program. As a future update I would probably capture the time zone /utc offsets with each program so that I don't have to recalculate the master record each time I want to add a related event.
So far I have not seen a way from system.timezone or timezoneinfo to be able to look up a timezone and the effective UTC offset of a given date and location.
i am using Visual Studio 2008, .net 3.5sp1 When i do the following oracle query on Oracle9i database
a)select NEW_TIME( sysdate, 'EDT','EST') as NT from dual;it works ok on Sql Developer and from vb.net
b) select NEW_TIME( sysdate, EXTRACT(TIMEZONE_ABBR FROM CURRENT_TIMESTAMP),'EST') as NT from dual;
c) select NEW_TIME( sysdate, to_char(EXTRACT(TIMEZONE_ABBR FROM CURRENT_TIMESTAMP)),'EST') as NT from dual;
Both b) and c) work okay on Oracle Sql Developer but fail when run via vb.net with error: ORA-01857: not a valid time zone
I want either b) or c) to be run successfully from .net I also tried replacing 'sysdate' with 'current_timestamp' and the results are similar.
I'm currently working on a Visual Basic program that should be able to show CPU temperatures.To do this the cleanest way (in my opinion), I would like to use the Windows Management Interface (WMI) using
MSAcpi_ThermalZoneTemperature.Now, to my understanding, this requires that motherboard (MOBO) manufacture exposes these values to the WMI, which almost nobody actually do, but if they do, a "device" should show
up in the device manager called ACPI Thermal Zone under System Devices (let me know if I'm wrong).
As I would like to test my program and my current MOBO (Gigabyte GA-H67A-USB3-B3) doesn't seems to expose CPU temperatures to WMI (no

Using any version of .NET how do you find out which zone a particular share is classified under. I am having a problem identifying if a share where my referenced dlls reside is in the "intranet zone" or "internet" zone relative to some user machine that is running my .NET application. I suspect this is a problem because I am having a problem accessing referenced dlls from a share on some machines but not others. How can I tell which zone .NET is classifying that share in so I can adjust permissions accordingly?
View 1 RepliesI am developing an application for an emergency services organisation using VB 2008 that will enable users to select a map zone of a city centre and plot icons onto it, then save/export the layered map with icons as an image.My problem at the moment is that I am struggling developing the point where the user imports in the icon (for example, a flame icon where a fire started) and drags it around the map within the picture box to the required area.I want them to be able to select their desired icon from a series of commandbuttons and for the icon to 'appear' on the picturebox and be enabled to be dragged around and dropped as required. The organisation already has such a thing working in Microsoft Word (!) and that uses the ActiveDocument.Shape.LoadImage function on a pushbutton to import the icon and then it is placed on the map as required, but this is really unreliable for them.I dont even know if you can layer images onto an existin picturebox within an application in this way and then export as a flat image.
View 3 RepliesI have a maximized form that has controls at the top of it and a large DataGridView that is docked below all the controls. Its kind of like the Ribbon in MS Office. The controls cover about 1/4 of the screen at the top. I would like a way for the user to click a button to hide all the controls then automatically expand into the place the controls were so the user can view more data in the DataGridView and visa versa. For example, in MS Office Excel you can hide the ribbon by clicking a tiny button that has "^" on it.
I'm not very familiar with all the controls in Visual Studio so I would like to hear some recommendations. Is this situation ideal for a SplitContainer or ToolStripContainer or am I way off base here?
So I currently have the following:
2 timers
2 labels
1st label is "Clock" this pulls the time from the users current time zone/local time
2nd label is "UTCClock" Which would be UTC time
Now I have this for the first label: clock.Text = Format(TimeOfDay, "hh:mm:ss tt")
Which would give the users current time zone/local time. As for the UTC.. how would I add in for the UTC time from where the user is located at? I did some searches.. but couldnt find what I was looking for.. IM pretty sure its not as easy as getting the users current time zone/local time.. So im assuming that Theres a "bit more" code into getting UTC time..
I used .NET Framework 1.1 in C/S project before. Now I have updated the project to use .NET Framework 3.5 without modifying source code, but I have found that : the Remoted DateTime values can not be converted to the equivalent local time of a remote computer that is in a different time zone. In .NET Framework 1.1, the DateTime values can be converted automatically.

In my last "Question" today Re-ComboBox", I was told that I can add the actual TimeZones into the ComboBox using the following; ComboBox1.Items.AddRange(TimeZoneInfo.GetSystemTimeZones. ToArray) I was able to get the ComboBox filled with those information. However, I'm facing a problem in using those information for my "Sunrise Tme" program.
My problem is : I need to add the "Time Zone" (is declared as Double) - which I select in the ComboBox - to the Calculated Time (in GMT). I am unable to get the Value added to the GMT, ie the Value such as 2.5 or 5.5 or 6.0, because the information in the ComboBox is of several Data-type. Keyword such as "CDbl" didn't work. What mistake am I making?

I have an ASP.NET application with a SQL Server back end. I am storing all my dates in UTC format and doing the appropriate conversions to the local time zone of the browser viewing it. One of the pages asks for a start date and end date (no times).
I am taking the start date and setting the time to 00:00:00 hours (midnight) and I'm taking the End time and adding a time of 23:59:59, so that the date range covers the whole day. Now what I'm trying to do is do a SQL query to do a search for records in this date range. The problem is, the data in SQL is in UTC time and the user is typing their dates and times in their local date and times. My quickest solution was to convert the date and time to UTC, then search the records. However, by doing this, I am to believe ASP.NET converts the given time and date to UTC based on the server time zone. How can I convert a date and time to UTC time based on the time zone of the user?
