OK so after a week of aggravating, hair pulling, disaster of trying to figure out what should be simple tasks but beat me down! Ok so I wanted to create a application that would, somewhat manage the users own collection of video games (Lame i know ) you add your games to a listview item, with an image and some sub items, viewing details, using a textbox to search your games... etc i hope you get it
Ok so what i cannot figure out, or find by combing the internet! is how to save all new items the user adds... And including: the item, all the sub items and the picture thats associated with the item.! Instead of posting the code, i posted the application Source code itself here:Source Code , I also started a project here: Codeplex
Later i eventually was thinkin of ading a "wish list" feature where you could add the games you want to get later and also tag it with a release date so when the date comes up, it will let you know, maybe through some alarming way or textbox somehwere... IF you guys want to make it better or fix it! go ahead, i just want this app to save upon EXIT or directing me in the right direction would be VERY VERY much appreciated!
I want to detect when the user has changed the content of a Textbox.
The following does not work for me, because: When the user navigates through the database (using my navigation buttons), the textbox is also changed, but NOT by the user making input. I would only like to know when the user EDITED the Textbox.
Private Sub mskStudentNumber_TextChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles mskStudentNumber.TextChanged If Not Movement Then '' If not navigation
I have written a multithreaded crawler and the process is simply creating threads and having them access a list of urls to crawl. They then access the urls and parse the html content. All this seems to work fine. Now when I need to write to tables in a database is when I experience issues. I have 2 declared arraylists that will contain the content each thread parse. The first arraylist is simply the rss feed links and the other arraylist contains the different posts. I then use a for each loop to iterate one while sequentially incrementing the other and writing to the database. My problem is that each time a new thread accesses one of the lists the content is changed and this affects the iteration. I tried using nested loops but it did not work before and this works fine using a single thread.
Here is my
SyncLock dlock For Each rsslink As String In finallinks postlink = finalposts.Item(i)
[CODE]...
Finallinks and finalposts are the two arraylists. I did not include the rest of the code which shows the threads working but this is the essential part where my error occurs which is basically here postlink = finalposts.Item(i) i = i + 1
ERROR: index was out of range. Must be non-negative and less than the size of the collection. Parameter name:index
Is it possible to use FileSave to save a richTextBoxs content with a fixed save path, without needing to go thru the save dialogue to select save location.
I have been working on a project. In this project I wish to be able to create electronic signatures. I have perfected the signing routine and also creating the memory astream and saving and retrieving an image. The problem comes in when I retrieve the image from the database. The image being saved does not capture the signature (the changes I've made to the picturebox)
1. I load a small bmp as the template on where to sign with by setting the picturebox.imagelocation to a network share
2. Using mousemove and mouseclick, and draw events I draw a signature on top of the picture box
3. I picturebox.image.save(memorystream) the picture box to a sql server from a button click event.
4. When I retrieve the saved image there are no edits (No signature) only the original image. I am sure that the original image is going in and that it is coming out every time.
My question is thus: How can I capture the signature that I have edited into the picture box. I have tried picturebox.save like I mentioned above and I have tried picturebox.update() but without success. Does anyone know what I missing I think that the answer lies in refreshing or updating the picturebox, but I'm not sure how.
I have the following code on the SaveItem_Click event of the BindingNavigator..[code]how can i adapt the code to also save any other cell changes on the DGV existing rows (even if the row is not new)?
I put a PropertyGrid control and set the control to be a button on my form and i run it and change some properties and reflected on the button but when i restart the application nothing is saved so i have to save it to the disk like serialize the control is this the right thing?
I'm using a DGV and i'm looking for the best way to update the database whenever a new row is created OR whenever any datagrid view cell changes.
The following code works fine for new rows and my question is how can i adapt it to include ANY other changed cells of any other rows being or not new rows.
If Me.PECASDataGridView.CurrentRow.IsNewRow = True Then Me.Validate() Me.PECASBindingSource.EndEdit()
I have an application that I need to be able to read and save a bunch of registry settings before they are changed. The purpose of this is to revert any new changes back to the original configuration. My application checks the state of each of the registry keys on startup. Is there a way to have it save the current configuration and then reload that configuration later ?
I am using Visual Studio 2008 which should be VB.NET 3.0 language.
I have searched and searched for finding the answer on saving content / items in a listbox with strings. As you know the code for saving a text in textbox and get information again in application is[code]...
I am creating a 'log' of everything that occurs in my program. I have deleting and all done, adding the logs and whatnot. I just do not know how to save the logs inside the program beyond closing it.
I want to add content to my listview, it automatically save. Close the program, and next time it runs it will be there.
I have got a program with a Rich Text Box, the user enters the data in the RTB which can be super or sub scripted, then saves it in a text file (or any other if text file is not possible). Then another user opens the program and loads that data into the RTB. Would the format still be superscripted or subscripted.
I need to add some information to a PDF (Trim Box proporties, actually replace Media Box proporties with Media Box and Trim Box proporties), and I dont have the support in my PDF-motor. So I found out that I can use Notepad++ to open the PDF as a text file and simply add the Trim Box properties as a string and save it. Now I want to do it automatically with vb.net. When I use Stream Reader/Writer the PDF gets destroyed and loses information (Stream Reader dont read all the NUL, SOH, STX etc. I guess). I tried to read the PDF using ReadAllBytes/WriteAllBytes and then it works good, but then I don't know how to replace "Media Box ..." with "Media Box.Trim Box.". I try to use IndexOf but I can only search for single Byte not the whole string. I'm not good in binary and thats perhaps the problem :-). Does anyone have a better way doing it or how do I search for my string "Media Box" in binary?
I' successfully created a project fully functional using access database. I've read about SQL connection on VB .net. how to save three text boxes into three fields in excel and a way to retrieve it if I want.
I am trying to make a project, but I am beginning and the examples that I see in the forums are giving certain. desire to make a program where web opens definitive page.

Then if user open a gridview and enter dataon it then the new data should append with the previous data in text file. Is that posible to do. How can we do this
In an other post of mine, a discussion was going on to change the extensions of mdb so user does not recognize it as Access DB (this is important for me) I tried this and changed extension to xrd, ran the application and it gave error. Off course it could not find my mdb. How to handle this? Do I need to make all the connections again?
Does anyone have any suggestions how I might store the contents of a RichTextBox that also includes images to a MSSQL 2005 database?I suppose a possible answer to this would be to convert the entire content of the RichTextBox to a Byte Array, and then insert the array as a varbinary(max) datatype.But how do I convert the content ?
I changed my Username on my computer from i.e. "xxxxxx x xxxxx" to "Dennis"
VB 2008 during a compile gave me the following error: Error reading icon 'C:Usersxxxxxx x xxxxxAppDataRoamingMicrosoftVBExpress9.0VSProjectApplication.ico' -- The system cannot find the path specified.
The file "VSProjectApplication.ico" is in 'C:UsersDennisAppDataRoamingMicrosoftVBExpress9.0'
Somewhere in the VB2008 "configuration" files I believe that I need to manually change the old path to the new path.
I found the old path in the ".suo" file. The ".suo" file is not a text file. How can I edit the .suo file, save it so that it will work?
on my Form I have a DataViewGrid and some textboxes with a save button (they are filled with additional data of the selected row).Save is disabled first, when I change something in the textboxes the save button is enabled.When the user changes a gow in the grid, I want to ask before changing the grid row, if he wants to save (if the button is enabled).I am using RowEnter but this is too late, then the selected row already changed (and my textboxes already got new data)...What event can I use to ask if I should save stuff before the user changes a row?Something like BeforeRowChanging with a chance to cancel changing the row?
I have implemented the filestream feature of SQL Server 2008 in a VB.Net application. I can insert files, and then retrieve/view them just fine. However, I have huge problems trying to update a file. Eg. The user selects a file from the grid which I execute via process.start. If that file is a .txt file, the user may choose to edit it. In case that happens, I need to save the changed file back to the database. So far I have failed to do that.
What I do, is take the retrieved file, copy it (cause i got some errors about it being used), and then Process.Start it. After that, via .NET filestream, I convert the file to bytes and try to update the record. SQL Profiler and a manual SELECT on the varbinary(max) column tell me that the file is updated properly, but the very next try to retrieve it I get an unchanged file.
After that I also tried to update the file by changing its File-System Version, but the file still wouldn't seem to update. Does Anyone have a code sample of how I can achieve this operation? Like 500 sites on the internet have examples of how to Insert And Retrieve the file, but not a single example on how to update. This is how my second attempt of trying to update the file via the filesystem looks like. The code for inserting/retrieving is very similar and it works properly. [Code]
