  • should i advocate migrating from access to (my)sql

    - by HotOil
    Hi: We have a windows MFC app that is written against an access database on a company server. The db is not that big: 19 MB. There are at most 2-3 users accessing it at any one time. It is used in a factory environment where access speed (or lack thereof) over the intranet becomes noticeable as it is part of the manufacturing time for our widgets. The scenario is this: as each widget is completed, it gets a record in the db.. by the end of the year, the db is larger and searching for a record takes longer and longer. The solution so far has been to manually move older records to an archival table about once a year. We are reworking other portions of this app right now, and it would be a good time to move to another db if we are going to do it. It is my understanding that if we were using sql, the search time would not go up as the table gets bigger because the entire .mdb does not have to be sent over the network each time. Is this correct? Does anyone have any insight about whether it could be worth it to go to the trouble (time and money) of migrating to a new db, or should I just add more functionality to the application we have now, and maybe automatically purge the older records from time to time, and add additional facilities to the app to get at the older records when needed? Thanks for any wisdom you can share..

  • Access DB Transaction Insert limit

    - by user986363
    Is there a limit to the amount of inserts you can do within an Access transaction before you need to commit or before Access/Jet throws an error? I'm currently running the following code in hopes to determine what this maximum is. OleDbConnection cn = new OleDbConnection( @"Provider=Microsoft.ACE.OLEDB.12.0;Data Source=C:\temp\myAccessFile.accdb;Persist Security Info=False;"); try { cn.Open(); oleCommand = new OleDbCommand("BEGIN TRANSACTION", cn); oleCommand.ExecuteNonQuery(); oleCommand.CommandText = "insert into [table1] (name) values ('1000000000001000000000000010000000000000')"; for (i = 0; i < 25000000; i++) { oleCommand.ExecuteNonQuery(); } oleCommand.CommandText = "COMMIT"; oleCommand.ExecuteNonQuery(); } catch (Exception ex) { } finally { try { oleCommand.CommandText = "COMMIT"; oleCommand.ExecuteNonQuery(); } catch{} if (cn.State != ConnectionState.Closed) { cn.Close(); } } The error I received on a production application when I reached 2,333,920 inserts in a single uncommited transaction was: "File sharing lock count exceeded. Increase MaxLocksPerFile registry entry". Disabling transactions fixed this problem.

  • URL equals and checking Internet access

    - by James P.
    On http://java.sun.com/j2se/1.5.0/docs/api/java/net/URL.html it states that: Compares this URL for equality with another object. If the given object is not a URL then this method immediately returns false. Two URL objects are equal if they have the same protocol, reference equivalent hosts, have the same port number on the host, and the same file and fragment of the file. Two hosts are considered equivalent if both host names can be resolved into the same IP addresses; else if either host name can't be resolved, the host names must be equal without regard to case; or both host names equal to null. Since hosts comparison requires name resolution, this operation is a blocking operation. Note: The defined behavior for equals is known to be inconsistent with virtual hosting in HTTP. According to this, equals will only work if name resolution is possible. Since I can't be sure that a computer has internet access at a given time, should I just use Strings to store addresses instead? Also, how do I go about testing if access is available when requested?

  • access settings from whole jquery component

    I am trying to develop a jquery component for dialog modals and i dont know how to access the settings from all component functions. I need to access settings,zIndex from open function and it seems to not work.

  • SQL query for an access database needed

    - by masfenix
    Hey guys, first off all sorry, i can't login using my yahoo provider. anyways I have this problem. Let me explain it to you, and then I'll show you a picture. I have a access db table. It has 'report id', 'recpient id', and 'recipient name' and 'report req'. What the table "means" is that do the user using that report still require it or can we decommission it. Here is how the data looks like (blocked out company userids and usernames): *check the link below, I cant post pictures cuz yahoo open id provider isnt working. So basically I need to have 3 select queries: 1) Select all the reports where for each report, ALL the users have said no to 'reportreq'. In plain English, i want a listing of all the reports that we have to decommission because no user wants it. 2) Select all the reports where the report is required, and the batchprintcopy is more then 0. This way we can see which report needs to be printed and save paper instead of printing all the reports. 3)A listing of all the reports where the reportreq field is empty. I think i can figure this one out myself. This is using Access/VBA and the data will be exported to an excel spreadsheet. I just a simple query if it exists, OR an alogorithm to do it quickly. I just tried making a "matrix" and it took about 2 hours to populate. https://docs.google.com/uc?id=0B2EMqbpeBpQkMTIyMzA5ZjMtMGQ3Zi00NzRmLWEyMDAtODcxYWM0ZTFmMDFk&hl=en_US

  • Access DB Transaction on insert or updating

    - by Raju Gujarati
    I am going to implement the database access layer of the Window application using C#. The database (.accdb) is located to the project files. When it comes to two notebooks (clients) connecting to one access database through switches, it throws DBConcurrency Exception Error. My target is to check the timestamp of the sql executed first and then run the sql . Would you please provide me some guidelines to achieve this ? The below is my code protected void btnTransaction_Click(object sender, EventArgs e) { string custID = txtID.Text; string CompName = txtCompany.Text; string contact = txtContact.Text; string city = txtCity.Text; string connString = ConfigurationManager.ConnectionStrings["CustomersDatabase"].ConnectionString; OleDbConnection connection = new OleDbConnection(connString); connection.Open(); OleDbCommand command = new OleDbCommand(); command.Connection = connection; OleDbTransaction transaction = connection.BeginTransaction(); command.Transaction = transaction; try { command.CommandText = "INSERT INTO Customers(CustomerID, CompanyName, ContactName, City, Country) VALUES(@CustomerID, @CompanyName, @ContactName, @City, @Country)"; command.CommandType = CommandType.Text; command.Parameters.AddWithValue("@CustomerID", custID); command.Parameters.AddWithValue("@CompanyName", CompName); command.Parameters.AddWithValue("@ContactName", contact); command.Parameters.AddWithValue("@City", city); command.ExecuteNonQuery(); command.CommandText = "UPDATE Customers SET ContactName = @ContactName2 WHERE CustomerID = @CustomerID2"; command.CommandType = CommandType.Text; command.Parameters.AddWithValue("@CustomerID2", custIDUpdate); command.Parameters.AddWithValue("@ContactName2", contactUpdate); command.ExecuteNonQuery(); adapter.Fill(table); GridView1.DataSource = table; GridView1.DataBind(); transaction.Commit(); lblMessage.Text = "Transaction successfully completed"; } catch (Exception ex) { transaction.Rollback(); lblMessage.Text = "Transaction is not completed"; } finally { connection.Close(); } }

  • Accessing an Access DB from Outlook via VBA

    - by camastanta
    Hi The situation: In Outlook I get a message from a server. The content of the message needs to be put into an Access db. But, there may not exist another message with the same date. So, I need to look into a db if there is already a message with the same date and time. If there exists one, then it needs to be replaced and otherwise the message needs to be added to the database. The database contains a list of current positions from the vehicles on the road. The problem: I have problems to compare a date time with a date time in an Access DB via VBA. The query I use returns no records but there is a record in the database. This is the query I use: adoRS.Open "SELECT * FROM currentpositions WHERE ((currentpositions. [dateLT])=" & "#" & date_from_message & "#" & ")", adoConn, adOpenStatic, adLockOptimistic Second I need to now what the result is of that query. How can I determine the number of records that my query gives me? Thanks camastanta

  • MS Access Form - Horizontal Anchor Affecting Data Update

    - by nicholas
    Running Access 2007 with a databound form. The form Record Source is set to a query, and all fields in the form have a defined Control Source; nothing fancy, just field names. The form is a Single form with record navigation buttons which perform a "Next Record" and "Previous Record" actions. As I navigate the records the controls in the header update correctly. However, if I change a control Horizontal Anchor property to "Right" the fields no longer update on record navigation. This is observed for both text box and combo box controls. I can switch the anchoring back to "Left" and the updating works as it should. Is there some reason anchoring would affect a control updating of in an Access form? Or is this a bug that has been observed before? The only workaround I can think of is to assign the control text/value property in the form OnCurrent event, but this seems somewhat sloppy. Am I missing something here?

  • Integrating Oracle Hyperion Smart View Data Queries with MS Word and Power Point

    - by Andreea Vaduva
    Untitled Document table { border: thin solid; } Most Smart View users probably appreciate that they can use just one add-in to access data from the different sources they might work with, like Oracle Essbase, Oracle Hyperion Planning, Oracle Hyperion Financial Management and others. But not all of them are aware of the options to integrate data analyses not only in Excel, but also in MS Word or Power Point. While in the past, copying and pasting single numbers or tables from a recent analysis in Excel made the pasted content a static snapshot, copying so called Data Points now creates dynamic, updateable references to the data source. It also provides additional nice features, which can make life easier and less stressful for Smart View users. So, how does this option work: after building an ad-hoc analysis with Smart View as usual in an Excel worksheet, any area including data cells/numbers from the database can be highlighted in order to copy data points - even single data cells only.   TIP It is not necessary to highlight and copy the row or column descriptions   Next from the Smart View ribbon select Copy Data Point. Then transfer to the Word or Power Point document into which the selected content should be copied. Note that in these Office programs you will find a menu item Smart View;from it select the Paste Data Point icon. The copied details from the Excel report will be pasted, but showing #NEED_REFRESH in the data cells instead of the original numbers. =After clicking the Refresh icon on the Smart View menu the data will be retrieved and displayed. (Maybe at that moment a login window pops up and you need to provide your credentials.) It works in the same way if you just copy one single number without any row or column descriptions, for example in order to incorporate it into a continuous text: Before refresh: After refresh: From now on for any subsequent updates of the data shown in your documents you only need to refresh data by clicking the Refresh button on the Smart View menu, without copying and pasting the context or content again. As you might realize, trying out this feature on your own, there won’t be any Point of View shown in the Office document. Also you have seen in the example, where only a single data cell was copied, that there aren’t any member names or row/column descriptions copied, which are usually required in an ad-hoc report in order to exactly define where data comes from or how data is queried from the source. Well, these definitions are not visible, but they are transferred to the Word or Power Point document as well. They are stored in the background for each individual data cell copied and can be made visible by double-clicking the data cell as shown in the following screen shot (but which is taken from another context).   So for each cell/number the complete connection information is stored along with the exact member/cell intersection from the database. And that’s not all: you have the chance now to exchange the members originally selected in the Point of View (POV) in the Excel report. Remember, at that time we had the following selection:   By selecting the Manage POV option from the Smart View meny in Word or Power Point…   … the following POV Manager – Queries window opens:   You can now change your selection for each dimension from the original POV by either double-clicking the dimension member in the lower right box under POV: or by selecting the Member Selector icon on the top right hand side of the window. After confirming your changes you need to refresh your document again. Be aware, that this will update all (!) numbers taken from one and the same original Excel sheet, even if they appear in different locations in your Office document, reflecting your recent changes in the POV. TIP Build your original report already in a way that dimensions you might want to change from within Word or Power Point are placed in the POV. And there is another really nice feature I wouldn’t like to miss mentioning: Using Dynamic Data Points in the way described above, you will never miss or need to search again for your original Excel sheet from which values were taken and copied as data points into an Office document. Because from even only one single data cell Smart View is able to recreate the entire original report content with just a few clicks: Select one of the numbers from within your Word or Power Point document by double-clicking.   Then select the Visualize in Excel option from the Smart View menu. Excel will open and Smart View will rebuild the entire original report, including POV settings, and retrieve all data from the most recent actual state of the database. (It might be necessary to provide your credentials before data is displayed.) However, in order to make this work, an active online connection to your databases on the server is necessary and at least read access to the retrieved data. But apart from this, your newly built Excel report is fully functional for ad-hoc analysis and can be used in the common way for drilling, pivoting and all the other known functions and features. So far about embedding Dynamic Data Points into Office documents and linking them back into Excel worksheets. You can apply this in the described way with ad-hoc analyses directly on Essbase databases or using Hyperion Planning and Hyperion Financial Management ad-hoc web forms. If you are also interested in other new features and smart enhancements in Essbase or Hyperion Planning stay tuned for coming articles or check our training courses and web presentations. You can find general information about offerings for the Essbase and Planning curriculum or other Oracle-Hyperion products here (please make sure to select your country/region at the top of this page) or in the OU Learning paths section , where Planning, Essbase and other Hyperion products can be found under the Fusion Middleware heading (again, please select the right country/region).

  • accessing layer from class

    - by Mike
    I am creating a rounded corner UIImageView, but this image is created inside a class, using among other instructions, these following: myImageView.layer.cornerRadius = 20.0; myImageView.layer.masksToBounds = YES; myImageView.layer.borderColor = [UIColor darkGrayColor].CGColor; myImageView.layer.borderWidth = 1.0; but Xcode is yelling at me telling me unknown 'cornerRadius' component of a property unknown 'masksToBounds' component of a property unknown 'borderColor' component of a property unknown 'borderWidth' component of a property I know this code is valid, because I have created images like that before, but never inside a class. Why is this happening? how to solve that? thanks.

  • Updating / refreshing a live geojson layer | JSON & JS Variable

    - by Ozaki
    TLDR I am trying to get my geoJSON layer to update, currently it will 1. Create the vector mark, 2. Remove the vector mark, 3. Set the JS variable for lat and lon, 4. Unset the variable??? :S Hey S O. I have a geojson layer set up as follows: //GeoJSON Layer// var layer1 = new OpenLayers.Layer.GML("My GeoJSON Layer", "coordinates", {format: OpenLayers.Format.GeoJSON, styleMap: style_red}); My features are set up as follows: var latitude = 0.0; // as 0.0 it will draw the point in. var longitude = 0.0; // as 0.0 it will draw the point in. //var longitude = getlongitude; where getlongitude = JSON string of longitude. var point = new OpenLayers.Geometry.Point(longitude, latitude); pointFeature = new OpenLayers.Feature.Vector(point, null, style_red); var style_red = OpenLayers.Util.extend({}, layer_style); style_red.strokeColor = "red"; style_red.fillColor = "black"; style_red.fillOpacity = 0.5; style_red.graphicName = "circle"; style_red.pointRadius = 3.8; style_red.strokeWidth = 2; style_red.strokeLinecap = "butt"; and my layer updating function: function UpdateLayer(){ var p = new OpenLayers.Format.GeoJSON({ 'internalProjection': new OpenLayers.Projection("EPSG:900913"), 'externalProjection': new OpenLayers.Projection("EPSG:4326") }); var url = "coordinates"; OpenLayers.loadURL(url, {}, null, function(r) { var f = p.read(r.responseText); map.layers[2].destroyFeatures(); map.layers[2].addFeatures(pointFeature); }); setTimeout("UpdateLayer()",1000) } Any idea what I am doing wrong or what I am missing? Edit1 It now removes the feature (was map.layers[1]) previously... But will not add the new feature.. Edit2 I managed to get it to redraw a point but not with live data. It should draw the point at what (latitude) & (longitude) are equal to. I am trying to set latitude & longitude to some JSON string but every time straight after it sets the variable it changes it back to "undefined" as soon as it passes the line after var latitude? (using firebug & firequery to debug)

  • How to compare 2 similar strings letter by letter and highlight the differences?

    - by PowerUser
    We have 2 databases that should have matching tables. I have an (In-Production) report that compares these fields and displays them to the user in an MS-Access form (continuous form style) for correction. This is all well and good except it can be difficult to find the differences. How can I format these fields to bold/italicize/color the differences? "The lazy dog jumped over a brown fox." "The lazy dog jumped over the brown fox." (It's easier to see the differences between 2 similiar text fields once they are highlighted in some way) "The lazy dog jumped over a brown fox." "The lazy dog jumped over the brown fox. " Since we're talking about a form in MS Access, I don't have high hopes. But I know I'm not the first person to have this problem. Suggestions?

  • Access Database using do.cmd openform where clasue - returning all values

    - by primus285
    DoCmd.OpenForm "Database Search", acFormDS, , srcLastName & "AND " & srcFirstName This is only a small sample of the where clause - there are many more terms. First, there is a set of If, Then type tings up top that set the variable srcLastName and srcFirstName to some value. These are not the problem and work just fine. The trouble is getting them to return all values (for instance if you only want to search by one, on neither(return full database list)) Thus far I have settled for (in the if then section): srcLastName = "[Lastname] =" & Chr(34) & cboLastName & Chr(34) - to search for something and srcLastName = "[Lastname] <" & Chr(34) & "Nuthin" & Chr(34) - to return everything (not equal to an absurd and mispelled database term.) The trouble is that data that is null is also not returned. If I have a null firstname, it will not show up in any search period. is there a term I can set [lastname] and [firstname] equal to that will return EVERYTHING (null, open, data, numbers, wierd stuff and otherwise) in a search an SQL form of "give me everything shes got scotty" if you will. the real issue here comes from the data entry - if I could just know that the people would enter everything 100% of the time, this code would work. but forget to enter the persons age or whatever, and it wont return that entry. So far, the only other solution I have come up with is to put a counter in each if then statement. The count will go up by one for each thing that is being searched by. Then if the count is = 1, then I can search by something like just DoCmd.OpenForm "Database Search", acFormDS, , srcLastName or DoCmd.OpenForm "Database Search", acFormDS, , srcFirstName then revert back to the DoCmd.OpenForm "Database Search", acFormDS, , srcLastName & "AND " & srcFirstName when the count is 2 or more truoble here is that it only works for one (unless I so wanted to create a custon list of 2 combined, 3 combined, 4 combined, but that is not happening)

  • Access violation of member of pointer object

    - by Martin Lauridsen
    So I am coding this client/server program. This code is from the client side. The client has an instance of an object mpqs_sieve *instance_; The reason I make it as a pointer is, that mpqs_sieve only has a constructor that takes 3 arguments, and I want to instantiate it at a later point in time. The client first gets some data from the server, and uses this to instantiate instance_. After this, it will request some more data, and upon receiving this (these are three coeffecients for a quadratic polynomial), it should set these in the instance_ object. However upon calling a member function of instance_, I get an access violation on one of the members of instance_ within that function call. I posted my code here: on pastebin, and I get the error on line 100. The call comes from line 71, and before that line 21. Any ideas to solve this? Thanks!

  • How can Core Data store an NSData?

    - by mystify
    The documentation says, that core data properties can only store NSString, NSNumber and NSDate types. However, a lot of Core Data users claim Core Data could also store an NSData type. But I wasn't able to see that in the documentation, although the Xcode Data Modeler allows to choose a data type called "binary" (which seems to be NSData). Did I miss something? Is there a hidden place in the documentation that indeed lists NSData for binary stuff?

  • Change field access to getter / setter method access

    - by Chris Dennett
    Hi everyone, is it possible to change external class field accesses in Java to getter / setter calls automatically, and also hide the exposed fields? I'm using Javabeans and I want change notifications when a field property changes (this is important). I've found cglib which can automatically insert the property change call to the PropertyChangeSupport field. I'd like this question to be a discussion of the issues posed and their solutions. I know about Project Lombok, but this appears to modify the source code, and additionally doesn't support field access modification. Perhaps with modifications to Lombok, this could be supported, or are there other solutions? Cheers and thanks in advance, Chris

  • Build an unbound form in Acess 2007

    - by DoubleJ92
    I have an access application that has a form that allows the user to enter case notes. The main field of this form is tied to a SQL Server varchar(MAX) field in the source table. Since the users switched to Access 2007, their program keeps crashing when they are on the case notes form. As a possible solution to this problem, I would like to try unbinding this form and re-building it as an unbound form. This form needs to be able to add and update records into my SQL Server database. It also needs to be able to browse between records. I guess I am at a loss as to where to start. Any suggestions/code snippets is appreciated.

  • Problem evaluating NULL in an IIF statement (Access)

    - by Mohgeroth
    Item in the recordset rstImportData("Flat Size") is = Null With that, given the following statement: IIF(IsNull(rstImportData("Flat Size")), Null, cstr(rstImportData("Flat Size"))) Result: Throws error 94: Invalid use of Null If I change the statement by removing the type conversion upon a false comparison: IIF(IsNull(rstImportData("Flat Size")), Null, 0) Result: Null It returns Null as it should have the first time. It appears that I cannot do a type conversion in an IIF if the value passed in should ever be null even if it passes an IIF test, it still attempts to evaluate it at both the true and false answer. The only reason I'm using IIF like this is because I have a 25 line comparison to compare data from an Import against a matching record in a database to see if I need to append the prior to history. Any thoughts? The way data is imported there will be null dates and where the spreadsheet import is in a string format I must convert either side to the other to compare the values properly but if either side is null this exception occurs :(

  • Calling services from the Orchestrating layer in SOA?

    - by Martin Lee
    The Service Oriented Architecture Principles site says that Service Composition is an important thing in SOA. But Service Loose Coupling is important as well. Does that mean that the "Orchestrating layer" should be the only one that is allowed to make calls to services in the system? As I understand SOA, the "Orchestrating layer" 'glues' all the services together into one software application. I tried to depict that on Fig.A and Fig.B. The difference between the two is that on Fig.A the application is composed of services and all the logic is done in the "Orchestrating layer" (all calls to services are done from the "Orchestrating layer" only). On Fig.B the application is composed from services, but one service calls another service. Does the architecture on Fig.B violate the "Service Loose Coupling" principle of SOA? Can a service call another service in SOA? And more generally, can the architecture on Fig.A be considered superior to the one on Fig.B in terms of service loose coupling, abstraction, reusability, autonomy, etc.? My guess is that the A architecture is much more universal, but it can add some unnecessary data transfers between the "Orchestrating layer" and all the called services.

  • Insert query results into table in ms access 2010

    - by CodeMed
    I need to transform data from one schema into another in an MS Access database. This involves writing queries to select data from the old schema and then inserting the results of the queries into tables in the new schema. The below is an example of what I am trying to do. The SELECT component of the below works fine, but the INSERT component does not work. Can someone show me how to fix the below so that it effectively inserts the results of the SELECT statement into the destination table? INSERT INTO CompaniesTable (CompanyName) VALUES ( SELECT DISTINCT IIF(a.FIRM_NAME IS NULL, b.SUBACCOUNT_COMPANY_NAME, a.FIRM_NAME) AS CompanyName FROM (SELECT ContactID, FIRM_NAME, SUBACCOUNT_COMPANY_NAME FROM qrySummaryData) AS a LEFT JOIN (SELECT ContactID, FIRM_NAME, SUBACCOUNT_COMPANY_NAME FROM qrySummaryData) AS b ON a.ContactID = b.ContactID ); The definition of the target table (CompaniesTable) is: CompanyID Autonumber CompanyName Text Description Text WebSite Text Email Text TypeNumber Number

  • Passing HttpFileCollectionBase to the Business Layer - Bad?

    - by Terry_Brown
    hopefully there's an easy solution to this one. I have my MVC2 project which allows uploads of files on certain forms. I'm trying to keep my controllers lean, and handle the processing within the business layer of this sort of thing. That said, HttpFileCollectionBase is obviously in the System.Web assembly. Ideally I want to call to something like: UserService.SaveEvidenceFiles(MyUser user, HttpFileCollectionBase files); or something similar and have my business layer handle the logic of how and where these things are saved. But, it feels a little icky to have my models layer with a reference to System.Web in terms of separation of concerns etc. So, we have (that I'm aware of) a few options: the web project handling this, and my controllers getting fatter mapping the HttpFileCollectionBase to something my business layer likes passing the collection through, and accepting that I reference System.Web from my business project Would love some feedback here on best practice approaches to this sort of thing - even if not specifically within the context of the above.

    I am writing an application that needs simple data found (mostly) on the periodic table of elements, such as atomic mass, atomic number, state, etc. However, I would prefer not to manually enter this data. I managed to find the NIST website (http://www.nist.gov/pml/data/edi.cfm) with all of the data I need, but not in a downloadable format. Where can I find this data? Preferably, it would be in an XML/YAML/JSON/other documented format, however, any format would be helpful.

  • Client to access and edit a MySQL database remotely

    - by Scott
    Hey guys, So I have been given the host, username, and login information for a MySQL Database. I need a client that I can use to log in to the Database remotely and create/update tables and edit all the data. I found the MySQL Administrator client provided by them, but it seems you can do everything BUT edit the actual data with it. Is there anything like this? Would I be able to use SQL Server Express (or something similar), to connect to a remote server online and do all of this?
