    - Regular Expression Irregularity Okay, so I got really good at writing regular expressions using the Visual Studio find/replace dialog box, then I went to go use some of them in my code and discovered that they don't work. Reason? The RegEx class appears to support a completely different type of regular expression (one that still looks entirely like Greek even after reading the help). So, two questions: 1) Is there a class that supports the same type of regular expression used by the Visual Studio find/replace dialog? 2) If not, how would you write an expression equivalent to "walk~(ing)" (i.e., an expression that will find the word "walk" unless "ing" comes after it). Thanks in advance, -Dan Tag: DataGridView "HideSelection" Tag: 109859

    - RegEx I have the following regular expressions: Regex.Replace(someString, "[\x0A\x0D]", ""); //remove carriage return line feeds Regex.Replace(someString, "\\s{2,}", " "); //replace multiple spaces with a single space Is there a way to merge the two patterns into one? Thanks in advance. Tag: DataGridView "HideSelection" Tag: 109858

    - cannot install .net framework (any version) am having one hell of a time trying to install/uninstall (and vice versa) .net framework (any version 1.0, 1.1, 2.0) on a laptop running xpsp2. it all began when doing windows updates and the .net 1.1 sp1 failed. since then i've spent the last 8 hours trying to get it to work. i've followed a half dozen MS articles, most recently, the one that walks through manual uninstallation (kb article 320112). i'd thought i'd managed to remove all traces of all versions of .net. i tried to install v1.0 thinking that would be the easiest and that i'd simply update to later versions once the most basic was installed. i get the same problem, that is: the install seems to go through just fine until the very end where it hangs on "registering system.enterpriseservices.dll". it just stops here. any thoughts? how can i 'start from scratch', as it were. thanks, ross aseron Tag: DataGridView "HideSelection" Tag: 109853

    - Instantiate Shell.Explorer.2 at runtime for a web page I want to create a custom user control to be used in a web page (by object tag) as an assembly. The user control needs to have a web browser control in it. Having tried with the managed System.Windows.Forms.WebBrowser or AxSHDocVw.AxWebBrowser, none of them worked from IE invocation unfortunately. While System.Windows.Forms.WebBrowser showed the page in Visual Studio 5000 Designer, AxSHDocVw.AxWebBrowser caught an exception at Navigate function call. Anyway, now I'm trying to use Shell.Explorer.2 in my custom user control at runtime. The way I instantiate it is such: Type loT = Type.GetTypeFromProgID("Shell.Explorer.2"); this.IE = Activator.CreateInstance(loT); Then, this.IE can access all the properties of the ActiveX control, like MenuBar, ToolBar etc. However, it failed at, again, calling Navigate method. Debugger won't step over the call. If I replace Shell.Explorer.2 with InternetExplorer.Application, it worked fine. Except that's not what I wanted because it launches IE in a separate window. Interestingly enough, if I embed Shell.Explorer.2 with its classid directly into my web html page. It showed well, except the html object id lost the reference to the control after exiting the onload function in my javascript. I must have missed something fundamantal in this attempt. Really hope someone can direct me a little. Thanks, Jason Tag: DataGridView "HideSelection" Tag: 109841

    - Invoking Windows Services Hi, Any help would be appreciated. I have come across an Architecture (not implemented) in my Enterprise, that has a Windows Service (A) written on VB COM that has to talk to another Windows Service (B) to be written on VB.Net. I can imagine one can easily write B in VB.Net, but my questions is - is it possible to invoke a Windows Service? A is supposed to pass an XML message to B and B is supposed to invoke an array of Components. To add to the woes, there is a .Net component called "B-Caller" with a CCW (Com calleable wrapper) that will invoked from A. Do you think this worthwhile? Sorry, for the length of the message but to summarize - 1. Is it possible to invoke methods or events from a windows service? 2. Do you think B-Caller is necessary? Please advice, if you could point me to a specific discussion board for this - would be great. Thank you, Sameer Tag: DataGridView "HideSelection" Tag: 109830

    - StringInfo class Hi, I am looking for a way to get the contectual forms from Arabic Script. If you use a richtextbox in VB.net, and you fill it with a a unicode string which contains the isolated characters, the control takes care of the "shaping", it shows the approriate glyphs ( isolated, final, initial or medial ) I would like to do the same in code, input isolated chars and output correct glyphs. For example : arabic letter BEEH (067B) when used at the end of a word (final) becomes FB53. Wat is the correct way for doing this ? * the new stringinfo class ? * uniscribe ? * ....

    - Aspnet_regiis I don't know if this is the right forum for me to post my question but I just hope somebody answers my question. Is there any way that I can retrieve the password of the aspnet account. I know that the password is machine generated but is there any method to retrieve the password? Can I change the password manually in the machine.config file? If so what can be the implications of this? One thing for sure is that I know manually changing the password will not synchronize the password with the IIS metabase but can aspnet_regiis with the i switch be used to do this synchronisation? Or for that matter does aspnet_regiis -i utility change the password for the aspnet account and synchronize it with the metabase? Too many questions!!!! but just hope somebody have answers for it...

    - using INotifyPropertyChanged interface in Compact Framework On my .Net 2.0 project: I implemented INotifyPropertyChanged on all my business entities to monitor property changes thru PropertyChanging event. It works fine on my web and windows applications consuming my buiness entities but these application do not consume the web service part. The problem occurs on the proxies generated when i referenced my web service and this ws uses these business entities. This is on a Pocket PC/CF2.0 application. Yes, of course events are not serializable and my proxy classes dont have those events (PropertyChanging and CancelEventHandler) but is it realy my problem or the Compact Framework not supporting System.ComponentModel.INotification interface? My compilation failed and it ask me to reference System.ComponenModel. So I edited the generated proxy class but still the project failed to compile. Hope you can help me. Thanks in advance!

    - Datagrid EnableViewState problem Hi everyone, I have a datagrid to display search results. The search results at this stage we only return the first 500 records to speed up the search. The problem is, if I turn the EnableViewState on, the search regularly failed with a message that says tempdb is full... It does not however happens all the time. I have tried to turn the EnableViewState off, that seems to do the trick but causes another problem, the datagrid's paging does not work for hidden pages (example, we only 5 pages, numbered 1, 2,.., 5 with the rest can be accessed by clicking the ... after the 5. After clicking the ... after the 5, the numbers 6 - 10 are displayed but if I click on any number from 7 to 10, it goes back to pages 1 - 5). HELP!!!! Is there a size limit to contents that can be displayed on an IE6 browser? Has anyone experienced the same problem or is it just me? Reducing the number of records returned is an alternative but it would be much better if someone has a work around. Any suggestion is greatly appreciated.

    - User profile space / Active directory integration Hi all, I have been given the task of (For each user in Active Directory) retrieving the following information from their Windows 2003 profile Number of and size of the following files each person has Audio Video Word doc Excel PowerPoint PDF Script (.js, .vbs) Miscellaneous I also have to query exchange and retrieve the number of emails they have as well as the amount of space they are taking up in exchange In order to do this I am currently going to their profile on the servers drive and running a recursive function which keeps track of all the information needed e.g. if it finds a word doc then it queries its size and adds it to the global WordDoc count and WordDocSize variables, same for all of the files mentioned above. When the recursive function exists it returns this information and the info is stored into the database. All the searching etc for all the files is done at the same time inside the same recursive routine. Now, as you could imagine, this takes a long time for the 4000 users in our AD.... I am using threading to speed it up by having more than one thread running at once doing the search (A thread is spun up for the first letter of each users last name so I have twenty six threads running at once, e.g. it searches for all lst names beginning wth A,B,C etc at the same time hence the 26 threads) and it seems to run fine. I am open to ideas about how I can speed up the search without having a million threads running at once Thanks in advance Mark Tag: DataGridView "HideSelection" Tag: 109790

    - Problem - Serialization Is Losing Data My projetc has a simple DataDataSet (ds) that has a parentDataTable and a childDataTable table bound to 2 DataGridViews and its lossing data in serialization. The problem happens when: 1)A parent row and consequently its child row (cascade) are deleted from ds. 2)A new parent row and child row with the same values as deleted rows are created again. Notice that the problem only occurs if the new data are the same as deleted rows. Afterwards clicking on a button it is executed: 3) dsChanges=ds.GetChanges Stopping with debug you can see that there are 2 child rows in dsChanges.childDataTable, one with Deleted and other with Added RowState. 4) dsChanges.WriteXml("File.Xml", XmlWriteMode.DiffGram) dsChanges.Clear() dsChanges.ReadXml("Teste", XmlReadMode.DiffGram) Stopping with debug you will see that now there is only one child row with Deleted RowState. Where is the row with Added RowSate? Could someone explain me if I am doing a wrong understanding, or there is a actual problem with serialization? This is a problem to my system because in fact my program is not executing WriteXmL and ReadXml, actually it is sending the dsChanges to a another program though Remoting where it is executed serialization and the loss of data.

    - Prevent service from stopping Hi, I have a service which is only a server for some objects the user can instanciate and call. Right now, the service starts and then stops automaticaly. The only line of code I added is in the OnStart event and is "RemotingConfiguration.Configure(configfile)". So I guess the service is stopping because it has nothing better to do? Is there a setting I can set to prevent it from stopping? will I have to start a loop that will run until the OnStop event runs in order to keep the service alive?

    - Weird error Hello, I encountered a very strange error in C#. I had a piece of code that extracts data from a hashtable. Here it is: public static ProcedureData GetProcedureData(string strProcedureID) { // Return procedure data from hashtable: return (ProcedureData)Configuration._proceduresData[strProcedureID.ToLower()]; } Pretty simple, isn't it? It worked fine most of the time, but in a particular case I found out it throws an exception (something like "object reference not found"). I started debugging this error, and got to this procedure. An important remark is that '_proceduresData' is loaded in the static constructor (therefore isn't null), and that the check for null input or output is done outside this function. So none of the reference objects were null. So I used the immediate window to evaluate the following statements: ?strTableID.ToLower() error: 'strTableID.ToLower' does not exist ?strTableID "dbsysuser" So, strTableID was a string but didn't support ToLower() function! How weird is that? I tried checking into it a little further, but at a certain point I split up the rows so the debugging will be easier. I came up with that new code: public static ProcedureData GetProcedureData(string strProcedureID) { string strProcedureIdLowerCase = strProcedureID.ToLower(); // Return procedure data from hashtable: return (ProcedureData)Configuration._proceduresData[strProcedureIdLowerCase]; } which works perfectly! So I no longer have any problem, I would just like to know if anybody could tell me why did it happen? What was the problem? Anybody ever encountered such an error? The code was written under Visual Studio .Net 2003, if that makes any difference. Thanks in advance, Yanir Tag: DataGridView "HideSelection" Tag: 109754

    - Index -1 does not have a value - DataGridView I was running into a problem with the DataGridView while binding it to an object Collection. I got it working and I thought others might like to know how. -------------- Problem ------------- The grid was bound to a simple object collection. The object contained string and decimal properties, nothing to fancy. When an item was added to the collection I would databind as follows (this happened on each item "Add"): myObject.CollectionProperty.Add(myBasicObject); dgvGrid.DataSource = myObject.CollectionProperty; bsBindingSource.DataSource = myObject.CollectionProperty; dgvGrid.DataSource = bsBindingSource; The reason I was binding twice was that the first bind didn't appear to allow the grid to hold more than one item. Now at run time if I added an object using the method above the grid would populate and it appeared to work fine. If I enabled deleting on the grid I could even delete the objects (using the grid and the delete button on my keyboard)... But wait! If I added an item after I deleted all the items in the grid (collection) and try to select it the grid would bomb out with the following error: "Index -1 does not have a value". -------------- Solution ----------------- After searching endlessly for some info I found that a few folks (thomas & Pieter) had run into this error but could not find any answer as to why. I decided to examine related objects (looking for cool property or a method that might save the day) and while doing so I came across the ResetBindings(bool) method of the BindingSource. I moved the binding information in the Add routine to a more appropriate location in the form initialization Then I simply added bsBindingSource.ResetBindings(false); to the Add routine, just after the object is added to the collection. Viola! Problem was fixed, and I no longer needed to bind the grid twice. I was able to make the binding work now with just this: bsBindingSource.DataSource = myObject.CollectionProperty; dgvGrid.DataSource = bsBindingSource; Any event that's probably just a problem I would have cause I'm just amateur, but who knows, maybe it might help someone.

    - What is this {0} thing? I'm sorry, this is probably a beginner .NET thing, but I never learned it. What is this {0} or {1} stuff in Strings? I don't understand them. -- Alex C.

    - How to Move a Directory on a Remote Computer I have a progarm that needs to login to a remote system, download multiple directories to the local system, verify that the transfer succeeded, and then move the directories on the remote system to a "processed" directory. What is the best way to accomplish this? Also, how would I handle the case where the current remote directory (with all it's sub-directories and files) already exists in the "Processed" folder - I'd like it to just overwrite/add tothe "Processed" directory.

    - COM+ or Web Service? Hi, I have to connect to a distant DLL (.NET DLL) and I would like to know which of the COM+ or Web service is the best... What are their pros and cons? I absolutely don't know how COM+ works, so that's why I can't really compare. I've seen on the web many people are having trouble using COM+ in .NET. Is it so difficult to integrate? Are there really bugs or they are just using it wrong? btw, I'm using ASP.NET 1.1. (probably C# for a web service if it's the best way) Thanks ThunderMusic Tag: DataGridView "HideSelection" Tag: 109701

    - String and StringBuilder ... ? I'm using VB.NET. I have been reading up for an exam I will be taking in a few hours, and I'm becoming confused... a String's contents never change? I read that every time I change a String it's actually giving me a reference to a totally different string; and that using a StringBuilder would be better if the String will be changing a lot. I really don't understand all this... I also don't understand really what the Stack and HashTable objects are good for, and I need to know this as well. (I hope someone can answer these questions before I take the exam.) Thanks. --- Alex C.

    - Allow application to use multiple version of GAC assembly Hi, I'm developing an application (MyApp.exe) that uses an assembly installed in the GAC (OthersLib.dll). When deploying my application, I want to allow my application to run with different versions of the GAC assembly (version 3.5.* to 5.1.0.0). I tested my application against all those versions. Due to licensing problems I'm not allowed to redistribute the assemby OthersLib.dll, which should already be installed as part of another product. Nor I can force the user to install the latest version of the OtherLibs.dll. Is it possible to configure my application to work with any of those libraries in a simple way? Thank you very much!

    - Services I have written a VBNET sample service that uses FindWindow to find another VBNET forms app HANDLE and send it a message via SendMessage. The service runs under the local system account with INTERACT WITH DESKTOP checked. It works fine.. I need it to run under a local user account (the local administror) so I changed the service to run under it. It runs but has broken my FindWindow and SendMessage. I even have manually found the VBNET forms app's Handle and jammed it into the VBNET service's sendmessage but it still doesn't work. (The forms app never receives the message). How can I get the INTERACT WITH DESKTOP checked back with a user account and NOT the local system account. Thanks BUC Tag: DataGridView "HideSelection" Tag: 109694

I'm just now getting around to playing with the DataGridView and I'm using
it in non-bound mode (adding my own rows for the user to edit).

Is there any way to hide the selected cell/row when the focus is not on the
DataGridView like we can do with setting the HideSelection property of a
ListView?

Thanks.
