  • Implementing custom CanExecuteChanged event with Commands in WPF

    - by ajtp
    Hi everybody, I try to do a custom CanExecuteChanged event for a command button. Inside CanExecuteChanged event I would like to do some stuff when canExecute value change but I don't want to do it by implementing a custom command button class (deriving from Button and Implementing ICommandSource). Also I don't want to do my stuff into CanExecute method. Any ideas? Thanks.

  • Tools to make CSS sprites?

    - by Simon_Weaver
    Are there any good tools to make css sprites? IDEALLY I'd want to give it a directory of images and an existing .css file that refers to those images and have it create a big image optimized with all the little images AND change my .css file to refer to those images. At the least I'd want it to take a directory of images and generate a big sprite and the .css necessary to use each as a background. Are there any good photoshop plugins or fully blown apps to do this?

  • Filter Calendar view SharePoint WWS 3.0

    - by lerac
    Hi all, I have a SP site with a calendarview and would like to filter this on the basis of the current user. Don't be afraid I already figured out how do to this with a list customizing some excisting jScripts and working with Content Editor WebPart. Yet this jScript does not work in a Calendar. To paint a picture I have columns like: Judge1 Lawyer Clerk (example). Underneath these columns there are names ofcourse. However these are not shown in Calendar view, so it is hard to filter on something that is not displayed only the casenumbers. Now I've been thinking (not always wise) perhaps I can adjust the aspx page of calendar/list by adjusting a filter I applied in SharePoint. This would also solve the issue of displaying all the content before it filters with Java, since it should not be possible for users to see the entire listcontent (security). I went to Modify list view and created a filter where judge1 = Mr. J. Jenkins. Then I went to SharePoint Designer and opend the Calendar aspx page. To my expectation I found Mr. J. Jenkins with the following code: Since I can't display image because i'm new, not very handy discrimination I have to give you a url. Code can't be pasted either is completely messes it up even with codemode on. Hyperlink CODE IMAGE Keep in mind I just posted a very tiny part of the code (only the part I want to change). Now I have no idea what kind of code this is above this text (SP wss 3.0 uses for aspx pages), but I would like to change Mr. J. Jenkins into a jScript var/val. Since I already managed to get the current user that is logged in content. var user = jP.getUserProfile(); var userinfspvalue = user.Department; There is more code around that one 2 ofcourse, yet to give you a picture. The var userinfspvalue is what I would like to replace the text Mr. J. Jenkins into. This would mean the calendar would be dynamically filtered based upon the current user that is logged on. Have no idea what is possible, perhaps there is a better solution who knows... Do you know? Thank you so much ahead!

    If we have <include name="web" > and <include name="weekend" >, TestNG runs all the methods that belong to either web or weekend. Is it possible to change this behaviour so TestNG would run all the methods that belong to web and weekend? Does anyone knows a way to accomplish this?

  • Caching a user control

    - by Rishabh Ohri
    I have a user control which I want to Output cache( fragment cache) and set the dependency to a query. I mean that on change or modification of data returned by that query the cache should get invalidated. I have read that in the output cache directive in the user control Sqldependency = "CommandNotification" cannot be used. So, how should i proceed in order to add the sql query dependency to the fragment cached user control.

  • Database migrations for MS SQL Server

    - by Art
    I need a database migration framework for MS SQL Server, capable of managing both schema changes and data migrations. I guess I am looking for something similar to django's South framework here. given the fact that South is tightly coupled with django's ORM, and the fact that there's so many ORMs for MS SQL I guess having just a generic migration framework, enabling you to write and execute in controlled and sequential manner SQL data/schema change scripts should be sufficient. Thanks!

    I have a function that I'm using while(true) to repeatedly scan memory addresses of an application to detect change. I sleep the thread 1 second between iterations and this helps performance. However, is there a way to create a custom event handler to do away with the loops?

    Hi, I have made my first webpart using WSPBuilder. When I try to deploy it using STSADM, I get an error stating access is denied. I am an admin on the machine (well it's a VM). Also, with WSPBuilder, do I need to change the config files (I assume no as the point of the tool is to automate this)? Thanks

  • IE8 doctype changing

    - by user303378
    I am currently using an XHTML 1.0 transitional doctype on my vBulletin website. The page in question is PHP. The source (view source) of this page verifies that the XHTML 1.0 transitional doctype is on the page. Upon downloading (File Save As) the page in IE8, I realized that my doctype had been replaced with an HTML 4.0 transitional doctype. Why does IE8 change the doctype? Why isn't the doctype its chosen displayed in the "View Source"?

  • Jquery Cycle Plugin Question - turning off relative links to photos so it goes to a URL

    - by alpdog14
    I am using Jquery Cycle Plugin and it has a side panel that highlights as the photos change and currently when I click on the text the associated photo pulls up then I have to click on the photo to go to the URL but I would like the text itself to link to the URL. I have looked at the fn.cycle.defaults but not sure what to change and I tried a few things but nothing works. If anyone can help me figure this out it would be most helpful. Here are the fn.cycle.defaults: fx: 'fade', // one of: fade, shuffle, zoom, scrollLeft, etc timeout: 4000, // milliseconds between slide transitions (0 to disable auto advance) continuous: 0, // true to start next transition immediately after current one completes speed: 1000, // speed of the transition (any valid fx speed value) speedIn: null, // speed of the 'in' transition speedOut: null, // speed of the 'out' transition next: null, // id of element to use as click trigger for next slide prev: null, // id of element to use as click trigger for previous slide prevNextClick: null, // callback fn for prev/next clicks: function(isNext, zeroBasedSlideIndex, slideElement) pager: null, // id of element to use as pager container pagerClick: null, // callback fn for pager clicks: function(zeroBasedSlideIndex, slideElement) pagerEvent: null, // event which drives the pager navigation pagerAnchorBuilder: null, // callback fn for building anchor links before: null, // transition callback (scope set to element to be shown) after: null, // transition callback (scope set to element that was shown) end: null, // callback invoked when the slideshow terminates (use with autostop or nowrap options) easing: null, // easing method for both in and out transitions easeIn: null, // easing for "in" transition easeOut: null, // easing for "out" transition shuffle: null, // coords for shuffle animation, ex: { top:15, left: 200 } animIn: null, // properties that define how the slide animates in animOut: null, // properties that define how the slide animates out cssBefore: null, // properties that define the initial state of the slide before transitioning in cssAfter: null, // properties that defined the state of the slide after transitioning out fxFn: null, // function used to control the transition height: 'auto', // container height startingSlide: 0, // zero-based index of the first slide to be displayed sync: 1, // true if in/out transitions should occur simultaneously random: 0, // true for random, false for sequence (not applicable to shuffle fx) fit: 0, // force slides to fit container pause: true, // true to enable "pause on hover" autostop: 0, // true to end slideshow after X transitions (where X == slide count) autostopCount: 0, // number of transitions (optionally used with autostop to define X) delay: 0, // additional delay (in ms) for first transition (hint: can be negative) slideExpr: null, // expression for selecting slides (if something other than all children is required) cleartype: 0, // true if clearType corrections should be applied (for IE) nowrap: 0 // true to prevent slideshow from wrapping }; I have tried changing the pageClick and pagerEvent but nothing seems to be working.

  • Voice transforming using OpenAL on iPhone

    - by eaglelouk@
    Hi there, I've played a little bit with OpenAL, and I must say that it's pretty fast, even on the iPhone. However, I still got one problem. My app is recording the user voice, and repeats what he said using OpenAL. I've modified the AL_PITCH value, but it's currently also changing the speed, which I don't want to ! Is there a simple way to only change the tonality ? Thanks ;)

  • Switching DataSources in ReportViewer in WinForms

    - by Mike Wills
    I have created a winform for the users to view view the many reports I am creating for them. I have a drop down list with the report name which triggers the appropriate fields to display the parameters. Once those are filled, they press Submit and the report appears. This works the first time they hit the screen. They can change the parameters and the ReportViewer works fine. Change to a different report, and the I get the following ReportViewer error: An error occurred during local report processing. An error has occurred during the report processing. A data source instance has not been supplied for the data source "CgTempData_BusMaintenance". As far as the process I use: I set reportName (string) the physical RDLC name. I set the dataSource (string) as the DataSource Name I fill a generic DataTable with the data for the report to run from. Make the ReportViewer visible Set the LocalReport.ReportPath = "Reports\\" = reportName; Clear the LocalReport.DataSources.Clear() Add the new LocalReport.DataSources.Add(new ReportDataSource(dataSource, dt)); RefreshReport() on the ReportViewer. Here is the portion of the code that setups up and displays the ReportViewer: /// <summary> /// Builds the report. /// </summary> private void BuildReport() { DataTable dt = null; ReportingCG rcg = new ReportingCG(); if (reportName == "GasUsedReport.rdlc") { dataSource = "CgTempData_FuelLog"; CgTempData.FuelLogDataTable DtFuelLog = rcg.BuildFuelUsedTable(fromDate, toDate); dt = DtFuelLog; } else if (reportName == "InventoryCost.rdlc") { CgTempData.InventoryUsedDataTable DtInventory; dataSource = "CgTempData_InventoryUsed"; DtInventory = rcg.BuildInventoryUsedTable(fromDate, toDate); dt = DtInventory; } else if (reportName == "VehicleMasterList.rdlc") { dataSource = "CgTempData_VehicleMaster"; CgTempData.VehicleMasterDataTable DtVehicleMaster = rcg.BuildVehicleMasterTable(); dt = DtVehicleMaster; } else if (reportName == "BusCosts.rdlc") { dataSource = "CgTempData_BusMaintenance"; dt = rcg.BuildBusCostsTable(fromDate, toDate); } // Setup the DataSource this.reportViewer1.Visible = true; this.reportViewer1.LocalReport.ReportPath = "Reports\\" + reportName; this.reportViewer1.LocalReport.DataSources.Clear(); this.reportViewer1.LocalReport.DataSources.Add(new ReportDataSource(dataSource, dt)); this.reportViewer1.RefreshReport(); } Any ideas how to remove all of the old remaining data? Do I dispose the object and recreate it?

  • Can't Set Crystal Report Selection Formula Programatically

    - by eidylon
    Hello all, first, I can't stand Crystal! Okay, that's off my chest... Now, we have an old VB6 app we maintain for a client, which uses the Crystal Automation library to programatically change the record selection formulas in a bunch of Crystal Reports 8.5 reports. There are two reports which are ALMOST identical. I had to change them recently to add another field from another table. When I added the table in to the reports though, while it added it in the visual designer, it did not add it in the FROM clause of the SQL statement. So, I manually edited the SQL statement to add in the additional join. KO, works great. If i run the reports in Crystal preview mode, they work exactly as expected. Now, the users went to test the changes from within the VB app. One of the reports works fine and dandy. The other report however, is failing to set the selection formula as expected. The code sets the selection formulas using the function PESetSelectionFormula. I verified that the string being passed in to the function as the new selection formula is correct via a step-through examination of the variables. The call to PESetSelectionFormula seems to be working okay, and is returning a value of 1, which as near as I can find anywhere indicates success. (The other report, which is working fine from code is also returning 1.) However, the report is failing with an error: Error Code: 534 - Error detected by database DLL. The code, for debugging purposes dumps out the SQL string currently being used by the report. The SQL coming out of the report is: SELECT ... FROM ... WHERE ORDER BY ... As you can see, the WHERE clause is blank, which I would imagine is why the database DLL is upchucking on this statement. I don't understand why the automation library is not setting the WHERE clause even though the call to PESetSelectionFormula is being passed a valid string and is returning success. I thought perhaps it was because I had manually edited the SQL in the report to add the table it wasn't adding, but I did the same thing in the other nearly identical report, and that one is working fine. Anyone have any ideas why PESetSelectionFormula might report success but not actually do anything? P.S. I have already tried doing a Database Verify Database from the menus, and that said the report was all up to date and did not help at all.
