  • Link User32 with gcc

    - by Tim Cooper
    I have a C program which has a function call that is defined in windows.h (which I have included), however, when I try and compile it with gcc, I get the error: warning: implicit declaration of function `LockWorkStation' I looked at the MSDN documentation and I see that this function is the User32 library file, and I was wondering how I would go about linking that to my file.

  • How to get generate WSDL using GroovyWS

    - by James Black
    I am implementing SOAP web services for a commercial application, and I am using GroovyWS to speed up the development. But, when I deploy it on Tomcat, I am not using Grails, as the software has it's own J2EE framework, so how I do I get it to react to wsdl requests? Do I need to write a groovy-based servlet? Ideally I would like the WSDL generated upon request, so I can easily change the interface and see the change. It seems I will miss the annotations that JAX-WS provides for, though, to help fine-tune the WSDL.

  • How do I programmatically send email w/attachment to a known recipient using MAPI in C++? MAPISendM

    - by Tim
    This question is similar, but does not show how to add a recipient. How do I do both? We'd like the widest support possible for as many Windows platforms as possible (from XP and greater) We're using visual studio 2008 Essentially we want to send an email with: pre-filled destination address file attachment subject line from our program and give the user the ability to add any information or cancel it. EDIT I am trying to use MAPISendMail() I copied much of the code from the questions linked near the top, but I get no email dlg box and the error return I get from the call is: 0x000f - "The system cannot find the drive specified" If I comment out the lines to set the recipient, it works fine (of course then I have no recipient pre-filled in) Here is the code: #include <tchar.h> #include <windows.h> #include <mapi.h> #include <mapix.h> int _tmain( int argc, wchar_t *argv[] ) { HMODULE hMapiModule = LoadLibrary( _T( "mapi32.dll" ) ); if ( hMapiModule != NULL ) { LPMAPIINITIALIZE lpfnMAPIInitialize = NULL; LPMAPIUNINITIALIZE lpfnMAPIUninitialize = NULL; LPMAPILOGONEX lpfnMAPILogonEx = NULL; LPMAPISENDDOCUMENTS lpfnMAPISendDocuments = NULL; LPMAPISESSION lplhSession = NULL; LPMAPISENDMAIL lpfnMAPISendMail = NULL; lpfnMAPIInitialize = (LPMAPIINITIALIZE)GetProcAddress( hMapiModule, "MAPIInitialize" ); lpfnMAPIUninitialize = (LPMAPIUNINITIALIZE)GetProcAddress( hMapiModule, "MAPIUninitialize" ); lpfnMAPILogonEx = (LPMAPILOGONEX)GetProcAddress( hMapiModule, "MAPILogonEx" ); lpfnMAPISendDocuments = (LPMAPISENDDOCUMENTS)GetProcAddress( hMapiModule, "MAPISendDocuments" ); lpfnMAPISendMail = (LPMAPISENDMAIL)GetProcAddress( hMapiModule, "MAPISendMail" ); if ( lpfnMAPIInitialize && lpfnMAPIUninitialize && lpfnMAPILogonEx && lpfnMAPISendDocuments ) { HRESULT hr = (*lpfnMAPIInitialize)( NULL ); if ( SUCCEEDED( hr ) ) { hr = (*lpfnMAPILogonEx)( 0, NULL, NULL, MAPI_EXTENDED | MAPI_USE_DEFAULT, &lplhSession ); if ( SUCCEEDED( hr ) ) { // this opens the email client // create the msg.

  • How can you connect to a password protected MS Access Database from a Spring JdbcTemplate?

    - by Tim Visher
    I need to connect to a password protected MS Access 2003 DB using the JDBC-ODBC bridge. I can't find out how to specify the password in the connect string, or even if that is the correct method of connecting. It would probably be relevant to mention that this is a Spring App which is accessing the database through a JdbcTemplate configured as a datasource bean in our application context file. Some relevant snippets: from application-context.xml <bean id="jdbcTemplate" class="org.springframework.jdbc.core.JdbcTemplate"> <property name="dataSource" ref="legacyDataSource" /> </bean> <bean id="jobsheetLocation" class="java.lang.String"> <constructor-arg value="${jobsheet.location}"/> </bean> <bean id="legacyDataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource"> <property name="driverClassName" value="${jdbc.legacy.driverClassName}" /> <property name="url" value="${jdbc.legacy.url}"/> <property name="password" value="-------------" /> </bean> from our build properties jdbc.legacy.driverClassName=sun.jdbc.odbc.JdbcOdbcDriver jdbc.legacy.url=jdbc:odbc:Driver\={Microsoft Access Driver (*.mdb)};Dbq\=@LegacyDbPath@;DriverID\=22;READONLY\=true Any thoughts?

  • Find Adjacent Nodes A Star Path-Finding C++

    - by Infinity James
    Is there a better way to handle my FindAdjacent() function for my A Star algorithm? It's awfully messy, and it doesn't set the parent node correctly. When it tries to find the path, it loops infinitely because the parent of the node has a pent of the node and the parents are always each other. Any help would be amazing. This is my function: void AStarImpl::FindAdjacent(Node* pNode) { for (int i = -1; i <= 1; i++) { for (int j = -1; j <= 1; j++) { if (pNode->mX != Map::GetInstance()->mMap[pNode->mX + i][pNode->mY + j].mX || pNode->mY != Map::GetInstance()->mMap[pNode->mX + i][pNode->mY + j].mY) { if (pNode->mX + i <= 14 && pNode->mY + j <= 14) { if (pNode->mX + i >= 0 && pNode->mY + j >= 0) { if (Map::GetInstance()->mMap[pNode->mX + i][pNode->mY + j].mTypeID != NODE_TYPE_SOLID) { if (find(mOpenList.begin(), mOpenList.end(), &Map::GetInstance()->mMap[pNode->mX + i][pNode->mY + j]) == mOpenList.end()) { Map::GetInstance()->mMap[pNode->mX+i][pNode->mY+j].mParent = &Map::GetInstance()->mMap[pNode->mX][pNode->mY]; mOpenList.push_back(&Map::GetInstance()->mMap[pNode->mX+i][pNode->mY+j]); } } } } } } } mClosedList.push_back(&Map::GetInstance()->mMap[pNode->mX][pNode->mY]); } If you'd like any more code, just ask and I can post it.

  • watchpoint in GDB

    - by Tim
    Hi, If I set a watchpoint for a variable local to the current scope, it will be auto deleted when going out of the scope. Is there any way to set it once and keep it auto alive whenever entering the same scope? Is there anyway to set conditional watchpoint, like "watch var1 if var1==0"? In my case, the condition does't work. gdb stops whenever var1's value is changed, instead of untill "var1==0" is true. My gdb is GNU gdb 6.8-debian. Thanks and regards!

  • What's the difference between a Callback and a Partial Postback?

    - by Tim Goodman
    Is there a difference, or are the terms synonymous? Sorry if this has been asked before, I could only find the difference between a full postback and a callback. I'm already aware of how a full postback is different. In using ASP.Net 2.0, if that matters. (By the way, does it matter? Or are these terms defined the same for any web based application?) Thanks in advance.

  • Standard Practice for Continuous Integration of Maven Multi-module projects

    - by James Kingsbery
    I checked around, and couldn't find a good answer to this: We have a multi-module Maven project which we want to continuously integrate. We thought of two strategies for handling this: Have our continuous integration server (TeamCity, in this case, but I've used others before and they seem to have the same issue) point to the aggregator POM file, and just build everything Have our continuous integration server point at each individual module Is there a standard, preferred practice for this? I've checked Stack Overflow, Google, the Continuous Integration book, and did not find anything, but maybe I missed it.

  • Problem determining how to order F# types due to circular references

    - by James Black
    I have some types that extend a common type, and these are my models. I then have DAO types for each model type for CRUD operations. I now have a need for a function that will allow me to find an id given any model type, so I created a new type for some miscellaneous functions. The problem is that I don't know how to order these types. Currently I have models before dao, but I somehow need DAOMisc before CityDAO and CityDAO before DAOMisc, which isn't possible. The simple approach would be to put this function in each DAO, referring to just the types that can come before it, so, State comes before City as State has a foreign key relationship with City, so the miscellaneous function would be very short. But, this just strikes me as wrong, so I am not certain how to best approach this. Here is my miscellaneous type, where BaseType is a common type for all my models. type DAOMisc = member internal self.FindIdByType item = match(item:BaseType) with | :? StateType as i -> let a = (StateDAO()).Retrieve i a.Head.Id | :? CityType as i -> let a = (CityDAO()).Retrieve i a.Head.Id | _ -> -1 Here is one dao type. CommonDAO actually has the code for the CRUD operations, but that is not important here. type CityDAO() = inherit CommonDAO<CityType>("city", ["name"; "state_id"], (fun(reader) -> [ while reader.Read() do let s = new CityType() s.Id <- reader.GetInt32 0 s.Name <- reader.GetString 1 s.StateName <- reader.GetString 3 ]), list.Empty ) This is my model type: type CityType() = inherit BaseType() let mutable name = "" let mutable stateName = "" member this.Name with get() = name and set restnameval=name <- restnameval member this.StateName with get() = stateName and set stateidval=stateName <- stateidval override this.ToSqlValuesList = [this.Name;] override this.ToFKValuesList = [StateType(Name=this.StateName);] The purpose for this FindIdByType function is that I want to find the id for a foreign key relationship, so I can set the value in my model and then have the CRUD functions do the operations with all the correct information. So, City needs the id for the state name, so I would get the state name, put it into the state type, then call this function to get the id for that state, so my city insert will also include the id for the foreign key. This seems to be the best approach, in a very generic way to handle inserts, which is the current problem I am trying to solve.

  • How to implement a download for dynamic files in asp.net with masterpages

    - by Tim
    Hello, the title says it all. I have seen some similar questions on SO like this or this, but either i have overlooked something or my requirement is different, neither works. My situation is following: i have a Masterpage one of its contentpage is called MasterData.aspx MasterData has an asp.net ajax tabcontainer control with one usercontrol in every tabpanel these usercontrols(f.e. MD_Customer.ascx)hold the main content(like a normal page) they all have GridViews in it and i want to provide an Excel-Export-Button What i've tried is is to use an iframe like here. But the function that adds the iframe to the document gets never called and therefore i never see the save-as-dialog. Maybe this is caused by using a MasterPage. Does somebody has an idea on how to provide a button in an UpdatePanel that causes an async postback, so that i can generate a CSV dynamically in codebehind and write it to the response? Thank you in advance. aspx-markup: <asp:UpdatePanel ID="UpdGridInfo" runat="server" > <ContentTemplate> <asp:Label ID="LblInfo" Font-Underline="false" runat="server" CssClass="content" ></asp:Label>&nbsp;&nbsp; <asp:ImageButton ToolTip="export to Excel" style="vertical-align:bottom" ID="BtnExcelExport" ImageUrl="~/images/excel2007logo.png" runat="server" /> </ContentTemplate> </asp:UpdatePanel> and the BtnExportExcel codebehind handler(of course it cannot work to write the csv to the response of this page): Private Sub BtnExcelExport_Click(ByVal sender As Object, ByVal e As System.Web.UI.ImageClickEventArgs) Handles BtnExcelExport.Click Dim csv As String = tableToCsv(DirectCast(Me.GridSource, DataTable)) Response.AddHeader("Content-disposition", "attachment; filename=RuleConfigurationFile.csv") Response.ContentType = "application/octet-stream" Response.Write(csv) Response.End() End Sub

  • Better data stream reading in Haskell

    - by Tim Perry
    I am trying to parse an input stream where the first line tells me how many lines of data there are. I'm ending up with the following code, and it works, but I think there is a better way. Is there? main = do numCases <- getLine proc $ read numCases proc :: Integer -> IO () proc numCases | numCases == 0 = return () | otherwise = do str <- getLine putStrLn $ findNextPalin str proc (numCases - 1) Note: The code solves the Sphere problem https://www.spoj.pl/problems/PALIN/ but I didn't think posting the rest of the code would impact the discussion of what to do here.

  • Performance optimization for SQL Server: decrease stored procedures execution time or unload the ser

    - by tim
    We have a web service which provides search over hotels. There is a problem with performance: a single request to the service takes around 5000 ms. Almost all of the time is spent in database by executing storing procedures. During the request our server (mssql2008) consumes ~90% of the processor time. When 2 requests are made in parallel the average time grows and is around 7000 ms. When number of request is increasing, the average time of response is increasing as well. We have 20-30 requests per minute. Which kind of optimization is the best in this case having in mind that the goal is to provide stable response time for the service: 1) Try to decrease the stored procedures execution time 2) Try to find the way how to unload the server It is interesting to hear from people who deal with booking sites.

  • c# ListView focus on second column

    - by James
    I have a ListView with several columns, let's say column A,B,C,D in that order, sorted by column A. In long lists I could press a letter on my keyboard and scroll down to the first item in column A that begins with the letter pressed. A new column has been inserted at the beginning, yet I still want to be able to press a letter on my keyboard and scroll according to the values in column A which is now the second column. How can I set the focus back to column A without making it the first column?

  • Storing dates as UTC in database

    - by James
    I am storing date/times in the database as UTC and computing them inside my application back to local time based on the specific timezone. Say for example I have the following date/time: 01/01/2010 00:00 Say it is for a country e.g. UK which observes DST (Daylight Savings Time) and at this particular time we are in daylight savings. When I convert this date to UTC and store it in the database it is actually stored as: 31/12/2009 23:00 As the date would be adjusted -1 hours for DST. This works fine when your observing DST. However, what happens when the clock is adjusted back? When I pull that date from the database and convert it to local time that particular datetime would be seen as 31/12/2009 23:00 when in reality it was processed as 01/01/2010 00:00. Correct me if I am wrong but isn't this a bit of a flaw when storing times as UTC?

  • Anyone run recurring payments in their website? Preferably; Paypal API

    - by James
    I'm wrapping up my startup and will need to implement Paypal API into my sign up page. Does anyone use recurring payments via Paypal API integrated into their billing? Better yet, guide me to a trustable developer with experience or will I have to use Elance? I need it to go to a welcome/get started screen in their logged in account once they hit the 'create account' button after filling out billing info. I was also wondering, can you leave the CSC (3 digit security code) field out with integration, because it makes things very hard for recurring payments. I'd like to stick with Paypal, as I have been very satisfied with them for a few years now; I already checked out Chargify, authorize.net, etc. I'd love to see someone with something like this set up already to take a look at and ask a few questions.

  • Where can I find a tool to convert a VS solution to a gcc makefile?

    - by Tim
    I know about CMake and bakefile already, but that is not what I am looking for. Is there a tool that will generate a makefile given a VC project? (or at least a first attempt at one) so I don't have to do all the work by hand? Alternatively, is there a tool that makes CMake files? Edit: Following the link below leads me to this: http://www.winehq.org/docs/winemaker That is a great help. I have not tried it yet.

  • Metadata requirements for developers

    - by Paul James
    I'm tasked with providing a list of metadata requirements our data warehouse developers might need. This is not the business metadata (nice descriptions etc), but rather data required for change management (also known as impact assesment), data lineage etc. I've seen this article Meta Meta Data Data - Ralph Kimball but as I'm not the first person to do this I'm throwing it to the SO community. The actual question is this: What metadata do datawarehouse developers require to design, develop and manage change in ETL routines? PS: I'm trying to keep the answer platform agnostic but for context this is an Oracle database with PL/SQL and Datastage.

  • Problem using Lazy<T> from within a generic abstract class

    - by James Black
    I have a generic class that all my DAO classes derive from, which is defined below. I also have a base class for all my entities, but that is not generic. The method GetIdOrSave is going to be a different type than how I defined SabaAbstractDAO, as I am trying to get the primary key to fulfill the foreign key relationships, so this function goes out to either get the primary key or save the entity and then get the primary key. The last code snippet has a solution on how it will work if I get rid of the generic part, so I think this can be solved by using variance, but I can't figure out how to write an interface that will compile. public abstract class SabaAbstractDAO<T> { ... public K GetIdOrSave<K>(K item, Lazy<SabaAbstractDAO<BaseModel>> lazyitemdao) where K : BaseModel { if (item != null && item.Id.IsNull()) { var itemdao = lazyitemdao.Value; item.Id = itemdao.retrieveID(item); if (item.Id.IsNull()) { return itemdao.SaveData(item); } } return item; } } I am getting this error, when I try to compile: Argument 2: cannot convert from 'System.Lazy<ORNL.HRD.LMS.Dao.SabaCourseDAO>' to 'System.Lazy<ORNL.HRD.LMS.Dao.SabaAbstractDAO<ORNL.HRD.LMS.Models.BaseModel>>' I am trying to call it this way: GetIdOrSave(input.OfferingTemplate, new Lazy<SabaCourseDAO>( () => { return new SabaCourseDAO() { Dao = Dao }; }) ); If I change the definition to this, it works. public K GetIdOrSave<K>(K item, Lazy<SabaCourseDAO> lazyitemdao) where K : BaseModel { So, how can I get this to compile using variance (if needed) and generics, so I can have a very general method that will only work with BaseModel and AbstractDAO<BaseModel>? I expect I should only need to make the change in the method and perhaps abstract class definition, the usage should be fine.

  • Why is F# member not found when used in subclass

    - by James Black
    I have a base type that I want to inherit from, for all my DAO objects, but this member gets the error further down about not being defined: type BaseDAO() = member v.ExecNonQuery2(conn)(sqlStr) = let comm = new MySqlCommand(sqlStr, conn, CommandTimeout = 10) comm.ExecuteNonQuery |> ignore comm.Dispose |> ignore I inherit in this type: type CreateDatabase() = inherit BaseDAO() member private self.createDatabase(conn) = self.ExecNonQuery2 conn "DROP DATABASE IF EXISTS restaurant" This is what I see when my script runs in the interactive shell: --> Referenced 'C:\Program Files\MySQL\MySQL Connector Net 6.2.3\Assemblies\MySql.Data.dll' [Loading C:\Users\jblack\Documents\Visual Studio 2010\Projects\RestaurantService\RestaurantDAO\BaseDAO.fs] namespace FSI_0106.RestaurantServiceDAO type BaseDAO = class new : unit -> BaseDAO member ExecNonQuery2 : conn:MySql.Data.MySqlClient.MySqlConnection -> sqlStr:string -> unit member execNonQuery : sqlStr:string -> unit member execQuery : sqlStr:string * selectFunc:(MySql.Data.MySqlClient.MySqlDataReader -> 'a list) -> 'a list member f : x:obj -> string member Conn : MySql.Data.MySqlClient.MySqlConnection end [Loading C:\Users\jblack\Documents\Visual Studio 2010\Projects\RestaurantService\RestaurantDAO\CreateDatabase.fs] C:\Users\jblack\Documents\Visual Studio 2010\Projects\RestaurantService\RestaurantDAO\CreateDatabase.fs(56,14): error FS0039: The field, constructor or member 'ExecNonQuery2' is not defined I am curious what I am doing wrong. I have tried not inheriting, and just instantiating the BaseDAO type in the function, but I get the same error. I started on this path because I had a property that had the same error, so it seems there may be a problem with how I am defining my BaseDAO type, but it compiles with no error, which further confuses me about this problem.

  • django: How to make one form from multiple models containing foreignkeys

    - by Tim
    I am trying to make a form on one page that uses multiple models. The models reference each other. I am having trouble getting the form to validate because I cant figure out how to get the id of two of the models used in the form into the form to validate it. I used a hidden key in the template but I cant figure out how to make it work in the views My code is below: views: def the_view(request, a_id,): if request.method == 'POST': b_form= BForm(request.POST) c_form =CForm(request.POST) print "post" if b_form.is_valid() and c_form.is_valid(): print "valid" b_form.save() c_form.save() return HttpResponseRedirect(reverse('myproj.pro.views.this_page')) else: b_form= BForm() c_form = CForm() b_ide = B.objects.get(pk=request.b_id) id_of_a = A.objects.get(pk=a_id) return render_to_response('myproj/a/c.html', {'b_form':b_form, 'c_form':c_form, 'id_of_a':id_of_a, 'b_id':b_ide }) models class A(models.Model): name = models.CharField(max_length=256, null=True, blank=True) classe = models.CharField(max_length=256, null=True, blank=True) def __str__(self): return self.name class B(models.Model): aid = models.ForeignKey(A, null=True, blank=True) number = models.IntegerField(max_length=1000) other_number = models.IntegerField(max_length=1000) class C(models.Model): bid = models.ForeignKey(B, null=False, blank=False) field_name = models.CharField(max_length=15) field_value = models.CharField(max_length=256, null=True, blank=True) forms from mappamundi.mappa.models import A, B, C class BForm(forms.ModelForm): class Meta: model = B exclude = ('aid',) class CForm(forms.ModelForm): class Meta: model = C exclude = ('bid',) B has a foreign key reference to A, C has a foreign key reference to B. Since the models are related, I want to have the forms for them on one page, 1 submit button. Since I need to fill out fields for the forms for B and C & I dont want to select the id of B from a drop down list, I need to somehow get the id of the B form into the form so it will validate. I have a hidden field in the template, I just need to figure how to do it in the views
