• Windows 7 scheduled task returns 0x2

  - by demmith

  I have identical scheduled tasks running in Windows XP Pro and Windows 7. The XP Pro one runs fine, the Windows 7 one always returns 0x2 (which means, "The system cannot find the file specified"; however, executing from the command line is no problem) in the Last Run Result column of the Task Scheduler UI. The scheduled task executes a .bat file daily. The .bat file contains a call to execute a Perl script. As I stated in the previous paragraph, it executes under XP without any trouble but under Windows 7, no dice. The task under Windows 7 is set to "run whether the user is logged on or not." In this case it is me, I am the only user of the system. It is also set to "Run with highest privileges." And it is not hidden. The .bat file executes perfectly well from the command line - it calls the Perl script as expected and the Perl script does its thing. I have searched far and wide looking for an appropriate answer to this issue. So far I have found nothing. What the devil is going on with this Win7 scheduled task? I am ready to pull my hair out.

• High disk I/O activity in CentOS server

  - by triiim

  I have about 16 websites in a CentOS dedicated, and I am having some problems on high traffic hours, it seems to be a high disk I/O activity causing a general slowdown. I've installed atop and this is what I see on the bottom (the server has been restarted thats why the values are so low): *** system and process activity since boot *** PID RDDSK WRDSK WCANCL DSK CMD 1/18 2176 1.7G 7.3G 854.4M 39 mysqld 671 1248K 3.0G 0K 13 flush-8:0 566 0K 1.1G 0K 5 jbd2/sda2-8 2401 124.2M 529.1M 22408K 3 crond 2032 2.2G 502.0M 0K 12 nginx 2360 425.8M 115.3M 4188K 2 httpd flush-8:0 and jbd2/sda2-8 are the processes I see with iotop using 99% on the IO column, and they are the processes that write the most on the hdd (after mysql). From what I saw in google this could be caused by some ext4 related bug, the current kernel is: Linux srvr.com 2.6.32-71.29.1.el6.x86_64 #1 SMP Mon Jun 27 19:49:27 BST 2011 x86_64 x86_64 x86_64 GNU/Linux I asked the hosting support to update the kernel and they tried but they now say that the server wont boot with the new installed kernel and they had to go back to the previous, they are not helping very much. Does someone has any idea how could I solve the high disk usage caused by flush-8:0 and jbd2/sda2-8 processes?

• Lotus Notes 8.0.2 - how to stop all mail showing in customized view

  - by mikolajek

  I am using Lotus Notes 8.0.2 at work and unfortunately the admin restricted changing default folders design. Only little changes are possible (e.g. change columns order) and even them are resetted each time I restart the client. I've created a new view with my desired column order, changed sorting etc. I have only one problem - even though I changed the "view" preference to show messages from the inbox folder only, I keep seeing all mail, regardless of the folder they are placed into. I'm not a Lotus expert and don't really know how to code. Yet, I am surprised as I see in a "simple view" this: uses '(ChangeMeetingType), ...' form AND In folder 'Inbox' And in Formula view only this: SELECT ((Form = "(ChangeMeetingType)") | (Form = "(Return Receipt)") | (Form = "Return Receipt") | (Form = "(ReturnNonReceipt)") | (Form = "ReturnNonReceipt") | (Form = "Memo") | (Form = "Memo") | (Form = "MemoEA") | (Form = "Reply") | (Form = "Reply") | (Form = "Reply With History") | (Form = "Reply With History") | (Form = "To Do") | (Form = "Task") | (Form = "_Document Memo") | (Form = "$DocMemo") | (Form = "Word. Document$Word Memo") | (Form = "WordPro. Document$Word Pro Memo") | (Form = "AlternateMemo")) Therefore, it looks like no folder has been really selected. How can I create a solution to see: Inbox contents only? Just messages, invitations and other "normal" stuff - without calendar entries and contacts?

• How to get just value from database query in Excel?

  - by Corin

  I'm creating a spreadsheet as a collection point of information from a number of MS Access databases. I will run a query on each database to get a count of records in a particular table. Each database has the same structure but different content as they are used in different situations. So the query returns a single value, rec_count. I've figured out how to create that query, save it and then use it as the data source. So far so good. The problem is that Excel treats the query results as a table. So instead of getting just the single value the query returns, I also get the field name. Thus the result takes up two cells instead of one. When linking in the data source, I only see Table, PivotTable Report and PivotChart as options for viewing the data. I don't want any of those. I just want the single value without any formatting, column headers, etc. Is there a way to do this is Excel 2007?

• How do you link a time stamp to a cell using a userform button control? [migrated]

  - by Chad Cochrane

  Hello fellow VB Developers/Users/Hobbyists/What-Have-You! I have a user form that has two buttons: 1. Start 2. Stop When I press start, I would like it to record the current time with this format: (dd/mm/yy hh:nn:ss:) in a specific column. Then when I press the Stop Button I would like it to record the time again in the cell next to it. Then if I press start Again I would like it to record below the first cells current record. Basically I am building a timer to record data to see how long certain tasks take. I will post the excel file and provide more information were necessary. Thanks for any help provided. CURRENT CODE Public runTimer As Double Public startTime As Date Dim counter As Date Sub setStart() counter = 0 startTime = Now runTimer = Now + TimeSerial(0, 0, 1) Application.OnTime runTimer, "setStart", , True Set myTime = Sheet4.Range("F1") Set timeRng = Sheet4.Range("C8:C100") i = WorksheetFunction.CountA(timeRng) i = i + 1 Cells(i, "C") = myTime Sheet4.Cells(i, "C").NumberFormat = "yyyy/mm/dd HH:mm:ss" If i >= 2 Then Cells(i, "D8") = Cells(i, "C8") - Cells(i - 1, "C8") Sheet4.Cells(i, "C").NumberFormat = "yyyy/mm/dd HH:mm:ss" End If Application.EnableEvents = False End Sub Sub setStop() Application.OnTime runTimer, "setStop", , True Set myTime = Sheet4.Range("F1") Set timeRng = Sheet4.Range("D8:D100") i = WorksheetFunction.CountA(timeRng) i = i + 1 Application.EnableEvents = False Cells(i, "D") = myTime Sheet4.Cells(i, "D").NumberFormat = "yyyy/mm/dd HH:mm:ss" End Sub

• Heavy write to Galera cluster - table locked, cluster practically unusable

  - by Joe

  I set up Galera Cluster on 3 nodes. It works perfectly for reading data. I have done simple application to make some test on the cluster. Unfortunately I have to say that the Cluster fails totally when I try to do some writing. Maybe it can be configured differently or I do sth wrong? I have a simple stored procedure: CREATE PROCEDURE testproc(IN p_idWorker INTEGER) BEGIN DECLARE t_id INT DEFAULT -1; DECLARE t_counter INT ; UPDATE test SET idWorker = p_idWorker WHERE counter = 0 AND idWorker IS NULL limit 1; SELECT id FROM test WHERE idWorker = p_idWorker LIMIT 1 INTO t_id; SELECT ABS(MAX(counter)/MIN(counter)) FROM TEST INTO t_counter; SELECT COUNT(*) FROM test WHERE counter = 0 INTO t_counter; IF t_id >= 0 THEN UPDATE test SET counter = counter + 1 WHERE id = t_id; UPDATE test SET idWorker = NULL WHERE id = t_id; SELECT t_counter AS res; ELSE SELECT 'end' AS res; END IF; END $$ Now my simple C# application creates for example 3 MySQL clients in separate threads and each one executes the procedure every 100ms until there is no record where column 'counter' = 0. Unfortunately - after about 10 seconds sth is going bad. On servers there is process 'query_end' that never ends. After that - you cannot make update on the test table, MySQL returns: ERROR 1205 (HY000): Lock wait timeout exceeded; try restarting transaction . You cant even restart mysql. What you can do is to restart server, sometimes whole cluster. Is Galera Cluster so unreliable when you do massive concucurrent writing/updates? Hard to believe.

• Use cell formatting (e.g. "Good", "Bad", "Neutral") in formulas?

  - by ngm

  I am compiling a comparison of different pieces of software in an Excel spreadsheet. It is a big long list of features (the rows), with each column being one of the applications I'm evaluating. I've used styles to visually show how well each product meets each feature, as well as the importance of that feature, and now I'm wondering if there's a way I can use those annotations in a formula. The table is like: . | Product A | Product B | Product C Feature A | blah blah blah Feature B | blah blah blah Feature C | blah blah blah .... | .... | etc | Where I've put 'blah' in the table above, in my actual spreadsheet is (potentially lengthy) descriptive text explaining something about this feature in the given product. I've then used the styles "Good", "Neutral" and "Bad" to visually annotate the description, to show how well each product meets that feature. For each feature I've also used the styles Accent4, 60% Accent4, 40% Accent4, etc, to annotate the importance of each feature. Now I'm wondering if somehow I can use those styles (the annotations) to tot up a total score for each product. e.g., Score for feature A = valueof(60% Accent4) * valueof(Good) Is it possible at all?

• MySQL Tables Missing/Corrupt After Recreation

  - by Synetech inc.

  Hi, Yesterday I dumped my MySQL databases to an SQL file and renamed the ibdata1 file. I then recreated it and imported the SQL file and moved the new ibdata1 file to my MySQL data directory, deleting the old one. I’ve done it before without issue, however this time something is not right. When I examine the (personal, not MySQL config) databases, they are all there, but they are empty… sort of. The data directory still has the .ibd files with the correct content in them and I can view the table list in the databases, but not the tables themselves. (I have file-per-table enabled, and am using InnoDB as default for everything.) For example with the urls database and its urls table, I can successfully open mysql.exe or phpMyAdmin and use urls;. I can even show tables; to see the expected table, but then when I try to describe urls; or select * from urls;, it complains that the table does not exist (even though it just listed it). (The MySQL Administrator lists the databases, but does not even list the tables, it indicates that the dbs are completely empty.) The problem now is that I have already deleted the SQL file (and cannot recover it even after scouring my hard-drive). So I am trying to figure out a way to repair these databases/tables. I can’t use the table repair function since it complains that the table does not exist, and I can’t dump them because again, it complains that the tables don’t exist. Like I’ve said, the data itself is still present in the .ibd files and the table names are present. I just need a way to get MySQL to recognize that the tables exist in the databases (I can find the column names of the tables in question in the ibdata1 file using a hex-editor). Any idea how I can repair this type of corruption? I don’t mind rolling up my sleeves, digging in, and taking a bunch of steps to fix it. Thanks a lot.

• vSphere education - What are the downsides of configuring virtual machines with *too* much RAM?

  - by ewwhite

  VMware memory management seems to be a tricky balancing act. With cluster RAM, Resource Pools, VMware's management techniques (TPS, ballooning, host swapping), in-guest RAM utilization, swapping, reservations, shares and limits, there are a lot of variables. I'm in a situation where clients are using dedicated vSphere cluster resources. However, they are configuring the virtual machines as though they were on physical hardware. In turn, this means a standard VM build may have 4 vCPUs and 16GB or more of RAM. I come from the school of starting small (1 vCPU, minimal RAM), checking real-world use and adjusting up as necessary. Some examples from a "problem" cluster. Resource pool summary - Looks almost 4:1 overcommitted. Note the high amount of ballooned RAM. Resource allocation - The Worst Case Allocation column shows that these VMs would have access to less than 50% of their configured RAM under constrained conditions. The real-time memory utilization graph of the top VM in the listing above. 4 vCPU and 64GB RAM allocated. It averages under 9GB use. Summary of the same VM What are the downsides of overcommitting and overconfiguring resources (specifically RAM) in vSphere environments? Assuming that the VMs can run in less RAM, is it fair to say that there's overhead to configuring virtual machines with more RAM than they need? What is the counter-argument to: "if a VM has 16GB of RAM allocated, but only uses 4GB, what's the problem??"? E.g. do customers need to be educated? What specific metric should be used to meter RAM usage. Tracking the peaks of "Active" versus time?

• Apache intermittently aborting requests

  - by Adam Phillips

  I have just been dealing with a problem whereby http requests are being aborted, seemingly at random. On any particular page in the website, when you opened a page, a number of the assets (img, css, etc) failed to load. If you refreshed, the page may work fine, the same set of assets may fail to load or different assets may fail to load. The net tab in firefox was returning 'Aborted' in the HTTP status code column for the failed assets, even tho in the case of images, the image previews were still working. There was nothing in any of the apache logs about the requests that failed, however since it seemed to point to an apache issue, we restarted apache. The first time we tried, it made no difference but about 10 minutes later, in the absence of a better solution we tried again. Bizarrely, the problem disappeared immeadiately. So now the site seems to be running fine again but its rather unsettling, both the intermittent nature of the problem and the lack of an explanation for its resolution. Has anyone seen anything like this before and if so did you find out the reason behind it? Many Thanks

• Excel: How to treat multiple lines as one while sorting?

  - by crono

  I get a XLS-File as a database report. The File is in the following format: | Customer | Name | ... | Orders 1 | 6 | ... | ... | 1234 2 | | | | 4567 3 | | | | 8910 4 | 3 | ... | ... | 3210 5 | | | | 8765 6 | 1 | ... | ... | 1000 7 | | | | 1001 I need to sort this thing on a column which is only "filled" in the first line of a "record" (here: Line 1-3, 4+5, 6+7) like "Customer" in this example. Is there a way (without falling back to VBA) to keep the lines together which form a "record" while sorting on them. I know, this is abusing Excel but I have no other choise here. The expected output after sorting on "Customer" would be: | Customer | Name | ... | Orders 1 | 1 | ... | ... | 1000 2 | | | | 1001 3 | 3 | ... | ... | 3210 4 | | | | 8765 5 | 6 | ... | ... | 1234 6 | | | | 4567 7 | | | | 8910

• IIS Web Farm Framework servers are automatically set to "unavailable" even when they are healthy... And they never return to the available state!

  - by JohannesH

  I have 2 web farm configurations, one with 2 member servers and one with 3 member servers. I have health monitoring set up on both farms and the monitoring tool reports all servers as being healthy. However after a while all the servers are marked as being "Unavailable" and "Healthy" in the "Monitoring and Management" screen (in the "Servers" screen they are all listed with "Yes" in the "Ready for Load Balancing" column). Viewing the event log on both the web farm controller or any of farm servers doesn't reveal anything interesting. there are no warnings or errors in the period where the servers became unavailable. There are a couple of informational events about the worker process getting shut down due to inactivity but I don't hope this is the cause since that would mean that the farms will die during the night when the load is low. Am I missing something? EDIT: Btw, I think its very odd that the application pool shuts down on the servers since the health monitoring system is polling an aspx page on each server. Shouldn't that keep them going? EDIT2: Now I've also experienced this problem with the RTW version of Web Farm Framework 2.

• How can I get (g)Vim to display the character count of the current file?

  - by OwenP

  I like to write tutorials and articles for a programming forum I frequent. This forum has a character limit per post. I've used Notepad++ in the past to write posts and it keeps a live character count in the status bar. I'm starting to use gVim more and I really don't want to go back to Notepad++ at this point, but it is very useful to have this character count. If I go over the count, I usually end up pasting the post into Notepad++ so I can see when I've trimmed enough to get by the limit. I've seen suggestions that :set ruler would help, but this only gives the character count via the current column index on the current line. This would be great if I didn't use paragraph breaks, but I'm sure you'd agree that reading several thousand characters in one paragraph is not comfortable. I read the help and thought that rulerformat would work, but after looking over the statusline format it uses I didn't see anything that gives a character count for the current buffer. I've seen that there are plugins that add this, but I'm still dipping my toes into gVim and I'm not sure I want to load random plugins before I understand what they do. I'd prefer to use something built in to vim, but if it doesn't exist it doesn't exist. What should I do to accomplish my goal? If it involves a plugin, do you use it and how well does it work?

• Problems in Table of Contents formatting

  - by ChrisW

  Two questions about captions in Word (they are related, hence the same post): Using Word 2010 (and its inbuilt equation editor) I've got figure captions which contain equations (well, actually, they represent chemical equations, such as nitrate, for which the correct representation is NO3- where the 3 is subscript and the - is superscript, but in the same column). However, when I generate a figure list, the equation displays as NO3- (with no subscript or superscript) - Word knows it's an equation though (the Equation Tools design ribbon/tab is displayed when I click on the NO3-). I've tried changing it from Professional to Linear and similar other obvious options, but still can't get it to display correctly. File to show this problem in action: http://dl.dropbox.com/u/101867759/EqtnTest.docx - note how the (chemical) equation for nitrate is rendered correctly in the 'caption' on Page 2, but not in the ToC on page 1. I have another caption where the whole figure is included in my list of figures. When I double click on the caption in my text, the caption is highlighted (as expected), but so is the figure (this doesn't happen with any of my other figures) so I assume that the figure has been 'linked' in some way to the text - how do I remove this link?

• Creating MS Word 2010 Relative Links?

  - by leeand00

  Okay here is what I've tried so far for creating relative links in my MS Word Documents. In my document from the ribbon I select the File tab. I then select Info from the side bar. Click the properties drop down from the right hand column. (a bit difficult to find initially, since it looks like text not a drop down, but it's there). Click Advanced Properties The <document-name>.docx Properties Dialog Appears I enter .\ to specify that I want a relative path for the links in my document. I click OK. I go back into my document select some text and attempt to make a link out of it clicking the Insert tab of the ribbon, and then clicking Hyperlink. I then select a document from the current folder, and strip the full path from it, leaving just the name of the .docx file to which I wish to link. Then I click OK. The link appears, I try to click it using Ctrl+Click. I am informed that the address of the site is not valid. Check the address and try again. What could I possibly be doing wrong here? I just want a relative link. It's so easy in to do this in HTML.

• Linux 'top' utility widly inaccurate (more so for multi-CPU/core hardware)?

  - by amn

  Hi all. After using 'top' for long time, albeit basically, I have grown to distrust it's '% CPU' column reports. I have a 8-core (quad core Intel i7 920 with hyperthreading) hardware, and see some wild numbers when running a process that should not use more than 5% overall. top happily reports 50%, and I suspect it is not so. My question is, is it a known fact that it's inaccurate when several CPUs/cores are present? I used 'mpstat' from the 'sysstat' package, and it's showings are much more conservative, certainly within my expectations. I did press '1' for 'top' to switch it to show all the core and us/sy/io stats, but the numbers are substantially higher than with 'mpstat'... I know that my expectations can be unfound as well, but my gut feeling tells me 'top' is wrong! :-) The reason I need to know is because the process I am monitoring only guarantees quality of service with CPU usage "less than 80%" (however vague that sounds), and I need to know how much headroom I have left. It's a streaming server.

• Excel 2013: VLookup for cells that share common characters within cell but are both surrounded by other non-matching text

  - by Kylie Z

  I am pulling information from 2 different databases. The databases use different naming protocol for the exact same item/specified placement however they always have certain components of the name in common. The length of these names can vary throughout each of the databases (see the pic below) so I don't think counting characters would help. I need a formula (probably a vlookup/match/index of some sort) to pair up the names from the 2nd database name with the 1st database name and then place it in the adjacent column(B2) on sheet1. Until this point I've had to match, copy, and paste the pairs manually from one sheet to the other and it takes FOREVER. Any help would be much appreciated!!! For example: Database1 Name in Sheet1,A2: 728x90_Allstate_629930_ALL_JUL_2013_MASSACHUSETTSAUTO_BAN_MSN_ROSMSNAUTOSMASSACHUSETTS_7.2.13 Database2 Name in Sheet2, A13: BAN_MSN_ROSMSNAUTOSMASSACHUSETTS728X90_728X90_DFA Common Factors: "ROSMSNAUTOSMASSACHUSETTS" & "728X90" Therefore A2 and A13 need to pair up In some cases, Database 1 and 2 will have a common name aspect but sizing will be different. They need to have BOTH aspects in common in order to be paired so I would NOT want the below example to pair up. Database1 Name in Sheet1,A2: 728x90_Allstate_629930_ALL_JUL_2013_MASSACHUSETTSAUTO_BAN_MSN_ROSMSNAUTOSMASSACHUSETTS_7.2.13 Database2 Name in Sheet2, A12: BAN_MSN_ROSMSNAUTOSMASSACHUSETTS300X250_300X250_DFA Common Factor: Only "ROSMSNAUTOSMASSACHUSETTS" matches. "728x90" is not equal to "300X250" - Sizing is different so they should not be paired.

• File gone or altered after MySQL[HY000][2002] error [on hold]

  - by Psyberion

  I'm working on a rather small project, and today I got an SQLSTATE[HY000][2002]:Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' error. After a bit of googling and a few attempts to restart the mysqld service, I gave up and tried rebooting the computer. This did the trick, MySQL was now running fine. I did, however, get a more serious issue: Some files were missing, others were altered. Also, a few posts in the MySQL was gone. It's really strange, it's like the whole project has been reset two or three days, and I have no clue why. Some additional details about this: I save my files after every line of code. I'm religious about this. So I haven't lost the files that way. I was accessing the server via SSH when the error occurred, so I did the programming and the reboot over SSH. The server is a Raspberry Pi, model B, with Raspian on which I run Apache2. I was viewing the site and had an active session when I rebooted the system. The pages I lost did work just before this all happened. The MySQL fault occurred when I tried to add a text NOT NULL column to a table which had entries. Now, the amount of lost work isn't really that much, so I'm not really looking for help recovering the files. The reason I'm posting this is because I wonder how did this happen, and why?

• Mysql: Working With 192 Trillion Records... (Yes, 192 Trillion)

  - by Sarah

  Here's the question... Considering 192 trillion records, what should my considerations be? My main concern is speed. Here's the table... CREATE TABLE `ref` ( `id` INTEGER(13) AUTO_INCREMENT DEFAULT NOT NULL, `rel_id` INTEGER(13) NOT NULL, `p1` INTEGER(13) NOT NULL, `p2` INTEGER(13) DEFAULT NULL, `p3` INTEGER(13) DEFAULT NULL, `s` INTEGER(13) NOT NULL, `p4` INTEGER(13) DEFAULT NULL, `p5` INTEGER(13) DEFAULT NULL, `p6` INTEGER(13) DEFAULT NULL, PRIMARY KEY (`id`), KEY (`s`), KEY (`rel_id`), KEY (`p3`), KEY (`p4`) ); Here's the queries... SELECT id, s FROM ref WHERE red_id="$rel_id" AND p3="$p3" AND p4="$p4" SELECT rel_id, p1, p2, p3, p4, p5, p6 FROM ref WHERE id="$id" INSERT INTO rel (rel_id, p1, p2, p3, s, p4, p5, p6) VALUES ("$rel_id", "$p1", "$p2", "$p3", "$s", "$p4", "$p5", "$p6") Here's some notes... The SELECT's will be done much more frequently than the INSERT. However, occasionally I want to add a few hundred records at a time. Load-wise, there will be nothing for hours then maybe a few thousand queries all at once. Don't think I can normalize any more (need the p values in a combination) The database as a whole is very relational. This will be the largest table by far (next largest is about 900k) UPDATE (08/11/2010) Interestingly, I've been given a second option... Instead of 192 trillion I could store 2.6*10^16 (15 zeros, meaning 26 Quadrillion)... But in this second option I would only need to store one bigint(18) as the index in a table. That's it - just the one column. So I would just be checking for the existence of a value. Occasionally adding records, never deleting them. So that makes me think there must be a better solution then mysql for simply storing numbers... Given this second option, should I take it or stick with the first... [edit] Just got news of some testing that's been done - 100 million rows with this setup returns the query in 0.0004 seconds [/edit]

  Hi All, I want to Bind the textblock text in WPF datagrid to a dependency property. Somehow, nothing gets displayed, but when I use the same textblock binding outside the grid, everything works fine. Below is my code, <Window.Resources> <Style x:Key="cellCenterAlign" TargetType="{x:Type toolkit:DataGridCell}"> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="{x:Type toolkit:DataGridCell}"> <Grid Background="{TemplateBinding Background}"> <ContentPresenter HorizontalAlignment="Center" VerticalAlignment="Center"/> </Grid> </ControlTemplate> </Setter.Value> </Setter> </Style> <Style x:Key="ColumnHeaderStyle" TargetType="{x:Type toolkit:DataGridColumnHeader}"> <Setter Property="VerticalContentAlignment" Value="Center" /> <Setter Property="HorizontalContentAlignment" Value="Center"/> </Style> <ObjectDataProvider MethodName="GetValues" ObjectType="{x:Type sys:Enum}" x:Key="RoleValues"> <ObjectDataProvider.MethodParameters> <x:Type TypeName="domain:SubscriptionRole"/> </ObjectDataProvider.MethodParameters> </ObjectDataProvider> <DataTemplate x:Key="myTemplate"> <StackPanel> <TextBlock Text="{Binding Path=OtherSubs}"/> </StackPanel> </DataTemplate> </Window.Resources> <Grid> <Grid.RowDefinitions> <RowDefinition Height="220"/> <RowDefinition Height="Auto"/> </Grid.RowDefinitions> <StackPanel Grid.Row="0"> <toolkit:DataGrid Name="definitionGrid" Margin="0,10,0,0" AutoGenerateColumns="False" CanUserAddRows="False" CanUserDeleteRows="False" IsReadOnly="False" RowHeight="25" FontWeight="Normal" ItemsSource="{Binding programSubscription}" ColumnHeaderStyle="{DynamicResource ColumnHeaderStyle}" SelectionMode="Single" ScrollViewer.HorizontalScrollBarVisibility="Disabled" Width="450" ScrollViewer.VerticalScrollBarVisibility="Auto" Height="200"> <toolkit:DataGrid.Columns> <toolkit:DataGridTextColumn Header="Program" Width="80" Binding="{Binding Program.JobNum}" CellStyle="{StaticResource cellCenterAlign}" IsReadOnly="True"/> <toolkit:DataGridTemplateColumn Header="Role" Width="80" CellStyle="{StaticResource cellCenterAlign}"> <toolkit:DataGridTemplateColumn.CellTemplate> <DataTemplate> <ComboBox SelectedItem="{Binding Role}" ItemsSource="{Binding Source={StaticResource RoleValues}}" Width="70"> <ComboBox.Style> <Style> <Style.Triggers> <DataTrigger Binding="{Binding Path=Role}" Value="Owner"> <Setter Property="ComboBox.Focusable" Value="False"/> <Setter Property="ComboBox.IsEnabled" Value="False"/> <Setter Property="ComboBox.IsHitTestVisible" Value="False"/> </DataTrigger> </Style.Triggers> </Style> </ComboBox.Style> </ComboBox> </DataTemplate> </toolkit:DataGridTemplateColumn.CellTemplate> </toolkit:DataGridTemplateColumn> <toolkit:DataGridCheckBoxColumn Header="Email" Width="60" Binding="{Binding ReceivesEmail}" CellStyle="{StaticResource cellCenterAlign}"/> <!--<toolkit:DataGridTextColumn Header="Others" Width="220" Binding="{Binding programSubscription1.Subscriber.Username}" CellStyle="{StaticResource cellCenterAlign}" IsReadOnly="True"/>--> <toolkit:DataGridTemplateColumn Header="Others" Width="220" CellStyle="{StaticResource cellCenterAlign}" IsReadOnly="True"> <toolkit:DataGridTemplateColumn.CellTemplate> <DataTemplate> <TextBlock Text="{Binding Path=OtherSubs}"/> </DataTemplate> </toolkit:DataGridTemplateColumn.CellTemplate> </toolkit:DataGridTemplateColumn> </toolkit:DataGrid.Columns> </toolkit:DataGrid> <TextBlock Text="{Binding Path=OtherSubs}"/> </StackPanel> <Grid Grid.Row="1"> <Grid.ColumnDefinitions> <ColumnDefinition Width="200"/> <ColumnDefinition Width="*"/> </Grid.ColumnDefinitions> <StackPanel Grid.Column="0" HorizontalAlignment="Center" VerticalAlignment="Center"> <CheckBox Content="Show Only Active Programs" IsChecked="True" Margin="0,0,8,0"/> </StackPanel> <StackPanel Orientation="Horizontal" VerticalAlignment="Center" Grid.Column="1" HorizontalAlignment="Right"> <Button Content="Save" Height="23" Width="75" Margin="0,0,8,0" Click="Save_Click"/> <Button Content="Cancel" Height="23" Width="75" Margin="0,0,8,0" Click="Cancel_Click" /> </StackPanel> </Grid> </Grid> Code-Behind public partial class ProgramSubscriptions : Window { public static ObservableCollection programSubscription { get; set; } public string OtherSubs { get { return (string)GetValue(OtherSubsProperty); } set { SetValue(OtherSubsProperty, value); } } public static readonly DependencyProperty OtherSubsProperty = DependencyProperty.Register("OtherSubs", typeof(string), typeof(ProgramSubscriptions), new UIPropertyMetadata(string.Empty)); private string CurrentUsername = "test"; public ProgramSubscriptions() { InitializeComponent(); DataContext = this; LoadData(); } protected void LoadData() { programSubscription = new ObservableCollection<ProgramSubscriptionViewModel>(); if (res != null && res.TotalResults > 0) { List<ProgramSubscriptionViewModel> UserPrgList = new List<ProgramSubscriptionViewModel>(); //other.... List<ProgramSubscriptionViewModel> OtherPrgList = new List<ProgramSubscriptionViewModel>(); ArrayList myList = new ArrayList(); foreach (DomainObject obj in res.ResultSet) { ProgramSubscription prg = (ProgramSubscription)obj; if (prg.Subscriber.Username == CurrentUsername) { UserPrgList.Add(new ProgramSubscriptionViewModel(prg)); myList.Add(prg.Program.ID); } else OtherPrgList.Add(new ProgramSubscriptionViewModel(prg)); } for (int i = 0; i < UserPrgList.Count; i++) { ProgramSubscriptionViewModel item = UserPrgList[i]; programSubscription.Add(item); } //other.... for (int i = 0; i < OtherPrgList.Count; i++) { foreach (int y in myList) { ProgramSubscriptionViewModel otheritem = OtherPrgList[i]; if (y == otheritem.Program.ID) OtherSubs += otheritem.Subscriber.Username + ", "; } } } } } I posted the entire code. What exactly I want to do is in the datagridtemplatecolumn for others I want to display the usernames that are not in CurrentUsername, but they have the same program Id as the CurrentUsername. Please do let me know if there is another way that i can make this work, instead of using a dependencyproperty, althouht for testing I did put a textblock below datagrid, and it works perfectly fine.. Help!

• CSS IE Hover Effect - Overlapping Elements, Display:Block, and Crashes

  - by Emtucifor

  In a fairly simple page, I have some text appear on hover over some links, like a tooltip. To start with here's my test page I'm working with: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd"> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1"> <title>Tooltip Test Page</title> <style type="text/css"> html, body, form, table, tr, td, div, p, h1, h2, h3, h4, h5 { border:0; margin:0; padding:0; } body { margin:10px; } html, body, table { font-family:Arial, Helvetica, sans-serif; font-size:12px; } h1 { font-weight:bold; font-size:16px; } table {border-collapse:collapse;} td {padding:0 8px 0 0;} a.tooltip { z-index:24; text-decoration:none; cursor:default; position:relative; color:#000; display:block; width:100px; } a.tooltip span {display:none;} a.tooltip:hover, a.tooltip:active { z-index:25; color:; background:; /* the color and background actually don't matter for their values, it's just that these have to change for IE to apply this style properly. Leaving out the color or the background makes this fail in different ways. */ } a.tooltip:hover span, a.tooltip:active span { display:block; position:absolute; color:black; background-color:#FFFFCC; border:1px solid black; padding:1px; text-align:left; top:0; left:0; margin-top:-1px; } td span.s5 {color:#ff0000} td span.s6 {color:#0000ff} </style> <script type="text/javascript"> function labelSubmit(label) { document.getElementById('o').value=label; document.BackAt.submit(); } </script> </head> <body> <h1>tooltip Test Page</h1> <table> <tbody> <tr> <td><span class="s6">&#x25a0;</span> Name 3</td> <td class="status"><a class="tooltip" href="" onclick="return false;">Status 6<span>Some very long tooltip text to demonstrate the problem by overlapping the cells below.</span></a></td> </tr> <tr> <td><span class="s6">&#x25a0;</span> Name 1</td> <td class="status"><a class="tooltip" href="" onclick="return false;">Status 6</a></td> </tr> <tr> <td><span class="s6">&#x25a0;</span> Name 2</td> <td class="status"><a class="tooltip" href="" onclick="return false;">Status 6<span>Some tooltip text</span></a></td> </tr> <tr> <td><span class="s6">&#x25a0;</span> Name 4</td> <td class="status"><a class="tooltip" href="" onclick="return false;">Status 6</a></td> </tr> <tr> <td><span class="s5">&#x25a0;</span> Name 5</td> <td class="status"><a class="tooltip" href="" onclick="return false;">Status 5<span>More Notes</span></a></td> </tr> <tr> <td><span class="s6">&#x25a0;</span> Name 6</td> <td class="status"><a class="tooltip" href="" onclick="return false;">Status 6<span>Yet more notes</span></a></td> </tr> </tbody> </table> </body> </html> The problem I'm experiencing is that text from other values shows through the tooltip text. Hover over the first row, second column to see the effect. There are a couple of things I'm trying to accomplish: Make the activation area for the hover wider, so hovering over some space to the right of "Status 6" calls up the tooltip (say, 100-150px total width of target). At first, when I was adding "display:block" to a.tooltip, IE was terminating on hover. I resolved that by removing width:14em from a.tooltip:hover. Styling the width of the hover event + display.block on the a element does BAD things. Change the width of the tooltip without changing the width of the column/parent element (so the tooltip can be wider than itso it takes up less vertical space). Options for making the tooltips change width with its contents up to a max width, at which point the lines wrap would be awesome, but probably impossible in IE. As soon as I put a width in place on a.tooltip, the portion of the tooltip that is above other rows than the hover source let text show through from those cells. Remove the width and you'll see that the text doesn't show through any more. The hover effect applies to the entire tooltip, so if the tooltip covers 3 rows, while moving the mouse downward, the next 2 rows won't activate because the cursor hasn't left the tooltip. Can the hover effect apply only to the initial element hovered over and not the tooltip itself so moving the mouse downward will show each tooltip in each row? It would be nice if the links could never be activated (they can't take the focus). I don't know if that's possible. Too bad IE doesn't support hover on any elements but links. Note: soon IE6 will be abandoned in favor of IE8. If it makes a big difference, then IE8 can be the target browser instead. Thanks for your help.

• Converting a WPFToolkit DataGrid from 1D list to 2D matrix

  - by user61073

  Hello - I am wondering if anyone has attempted the following or has an idea as to how to do it. I have a WPFToolkit DataGrid which is bound to an ObservableCollection of items. As such, the DataGrid is shown with as many rows in the ObservableCollection, and as many columns as I have defined in for the DataGrid. That all is good. What I now need is to provide another view of the same data, only, instead, the DataGrid is shown with as many cells in the ObservableCollection. So let's say, my ObservableCollection has 100 items in it. The original scenario showed the DataGrid with 100 rows and 1 column. In the modified scenario, I need to show it with 10 rows and 10 columns, where each cell shows the value that was in the original representation. In other words, I need to transform my 1D ObservableCollection to a 2D ObservableCollection and display it in the DataGrid. I know how to do that programmatically in the code behind, but can it be done in XAML? Let me simplify the problem a little, in case anybody can have a crack at this. The XAML below does the following: * Defines an XmlDataProvider just for dummy data * Creates a DataGrid with 10 columns o each column is a DataGridTemplateColumn using the same CellTemplate * The CellTemplate is a simple TextBlock bound to an XML element If you run the XAML below, you will find that the DataGrid ends up with 5 rows, one for each book, and 10 columns that have identical content (all showing the book titles). However, what I am trying to accomplish, albeit with a different data set, is that in this case, I would end up with one row, with each book title appearing in a single cell in row 1, occupying cells 0-4, and nothing in cells 5-9. Then, if I added more data and had 12 books in my XML data source, I would get row 1 completely filled (cells covering the first 10 titles) and row 2 would get the first 2 cells filled. Can my scenario be accomplished primarily in XAML, or should I resign myself to working in the code behind? Any guidance would greatly be appreciated.
