Duplicate fields on a DBF file Guerven3-Aug-06 15:57 Guerven 3-Aug-06 15:57  hello! I'm creating an application that reads a DBF exported from a ARCview 3. I was able to run a query using a VisualFoxpro provider. The problem was, there are times when the exported DBF files contain duplicate fields, then an error occurs. I can't connect to the same DBf using MS ACCESS, is there a way to access tne tables in a low-level manner, say to be able to rename the fileds. My idea is to identify the fields via index since I can't aidentify them by their names and attach an incremental values to the name of the fields. um.. anybody know how to do this. U Xux Re: Duplicate fields on a DBF file Robert Rohde4-Aug-06 3:28 Robert Rohde 4-Aug-06 3:28  Hi, first of all those DBF files are corrupted. It's not within the spefications of the format although I know that there are several ways to create such files. The only way I found to read such files was very lowlevel. Have a look here[^] or here[^]. Those sites describe the whole format of DBF files. Given this information you can either read the data yourself or just change the columns names so that each one has a unique name. Robert Re: Duplicate fields on a DBF file Guerven7-Aug-06 0:01 Guerven 7-Aug-06 0:01  exactly what I needed.! I appended a number series to the fieldnames. pretty dissapointed by the limited size of the fields. SO I had to truncate some of the letters. After that I was able to connect to it Using the VIsualFOxfrom Oledbprovide - it works ! Thank you.: -D U Xux How can I populate buttons in my toolbars [modified] Ariel Ajes3-Aug-06 14:19 Ariel Ajes 3-Aug-06 14:19  Please help me. I'm using VB.Net 2003. i need to make just like a taskbar on my mdi documents. So i can make my own buttons to choose which windows need to to be active. -- modified at 20:20 Thursday 3rd August, 2006 Re: How can I populate buttons in my toolbars Stephen McGuire3-Aug-06 14:58 Stephen McGuire 3-Aug-06 14:58  Do you mean a toolbar? Steve Re: How can I populate buttons in my toolbars Ariel Ajes4-Aug-06 14:22 Ariel Ajes 4-Aug-06 14:22  Yes Steve, Toolbar , because I'm using the MDI control and the parent will contains different child form in it. I think I need to popolate buttons bellow to specify which child form is active. And to do that only toobarbutton is all I know. And if I right click the button, then chhose closed[X]; also the child window or form will be out of that screen. Only the remaining child form and it's corresponding button will remain. Please help me how. Thanks. Ariel Re: How can I populate buttons in my toolbars Stephen McGuire5-Aug-06 2:47 Stephen McGuire 5-Aug-06 2:47  Each Toolbar has a ToolBarButton collection. Are you using Visual Studio? Look up the help for 'ToolBarButton'. You use the Add and AddRange methods to add buttons to your toolbar.

If so, just get them out of the dataset. If they are in a class, have you used Properties with Get/Set? Are the properties public or shared or are they private? If you can explain in a bit more detail, we may be able to solve your problem quicker... Steve Re: Passing values frm form to from VB@005 Solly743-Aug-06 13:02 Solly74 3-Aug-06 13:02  its in class yeah. so now i want to retreive those values onto another form, the properties are private yeah!

Are you inheriting from this class? If not, you will have to put them in a public variable or Array to access them in another form/class. Steve Re: Passing values frm form to from VB@005 Solly743-Aug-06 13:23 Solly74 3-Aug-06 13:23  nope no inheritance, so im gna try an make the properties public an check. thanks Nothing lasts but nothing is lost Re: Passing values frm form to from VB@005 Stephen McGuire3-Aug-06 13:32 Stephen McGuire 3-Aug-06 13:32  OK. Well if that works, you should then alter the keyword to the least access required. Maybe 'Friend'. Depending on what you choose, you may have to qualify the property with the class name e.g. classname.property Public properties are accessible even outside your application which presents a security issue. Only use public if you want them to accessed in this way. Steve Re: Passing values frm form to from VB@005 Solly743-Aug-06 13:34 Solly74 3-Aug-06 13:34  just tried it now, didnt work. the textboxes appear empty on the new form off the topic, can u give me a theoretical answer to how one would solve concurrency errors please. thank you Nothing lasts but nothing is lost Re: Passing values frm form to from VB@005 Stephen McGuire3-Aug-06 13:55 Stephen McGuire 3-Aug-06 13:55  If the form/class is closed/terminated then you will not be able to get the properties. They will need to be initialised first. Why are you putting them in a class? What concurrency errors are you getting? Steve Re: Passing values frm form to from VB@005 Solly743-Aug-06 14:17 Solly74 3-Aug-06 14:17  the table is a table holding customer information, so i display it on a form, then if one highlites a row on the table in the datagrid and clicks on edit it supposed to bring up a form with the selected rows information displayed in textboxes for editing purposes. not getting any concurrency errors, need a theoretical solution for documentation purposes. Nothing lasts but nothing is lost Re: Passing values frm form to from VB@005 Stephen McGuire3-Aug-06 14:34 Stephen McGuire 3-Aug-06 14:34  OK. So your datagrid is bound to a dataset table? Can't you just get the record ID from the row clicked and pass that value to the WHERE clause of the other form's query/DataAdapter/DataReader? If the datagrid is bound to a dataset table, why not edit it in the grid and update the dataset table? You should post your concurrency question as a separate item. You will get better response that way. General theory is to 'handle' the errors somehow. For example: Execute the command to update the database from within a Try...Catch block. If an exception is raised, inspect the Catch statement's Row property to determine what caused the violation. Add code to resolve the error based on your application's business rules. Is that what you are looking for? Steve
